SBR Rubber (Styrene-Butadiene Rubber)

SBR is the most widely used rubber in UK flooring. Made from styrene and butadiene monomers, it is the synthetic rubber of choice for gyms, warehouses, factories, and general commercial applications. Much of the SBR flooring sold in the UK is recycled crumb rubber — reclaimed from used car and truck tyres.

Why SBR Dominates Indoor Flooring

SBR's combination of cost-effectiveness, abrasion resistance, and availability makes it the go-to choice for the majority of UK rubber flooring projects. It performs exceptionally well under constant foot traffic, dropped weights, and rolling loads — the core demands of gym and industrial environments.

✅ Advantages

  • Lowest cost: 20-40% cheaper than EPDM per m²
  • Excellent abrasion resistance: Handles heavy traffic and dropped weights
  • Durable indoors: 10-20 year lifespan under normal commercial use
  • Widely available: Most gym tiles and rolls in the UK are SBR
  • Eco-credentials: Recycled tyre content reduces landfill waste
  • Easy to cut and install: Consistent density, cuts cleanly

❌ Disadvantages

  • UV degradation: Cracks and fades outdoors within 2-3 years
  • No oil resistance: Swells and degrades in hydrocarbon environments
  • Limited colour palette: Typically black or dark grey only
  • Initial odour: New rubber smell lasting 2-4 weeks
  • Not for extreme cold: Can harden below -20°C

Typical SBR Flooring Thicknesses & Uses

Thickness Application Load Type
4mm–6mm Light gym areas, aerobics, corridor matting Light foot traffic
8mm–10mm General gym floors, free weights areas Moderate weights, cardio equipment
12mm–15mm Weightlifting platforms, heavy machine areas Heavy weights, dumbbells to 50kg
18mm–25mm Olympic lifting, powerlifting zones Olympic bars, heavy drops
8mm–12mm Industrial warehouse flooring Forklift-rated (check spec)

Where to Buy SBR Rubber Flooring

SBR rolls, tiles, and sheets are available across our range. Most products sold under descriptions like "gym rubber tiles", "rubber matting rolls", or "heavy duty rubber sheet" will be SBR unless specifically stated otherwise.

EPDM Rubber (Ethylene Propylene Diene Monomer)

EPDM is a high-performance synthetic rubber engineered for outdoor environments. Its molecular structure incorporates diene monomers that create outstanding resistance to UV radiation, ozone, and extreme temperatures — the very conditions that destroy SBR. In the UK, EPDM is the material of choice for playground safety surfaces, rooftop terraces, pool surrounds, and outdoor gym areas.

Why EPDM Is the Only Choice for Outdoors

SBR rubber contains carbon-carbon double bonds in its polymer chain that react with atmospheric ozone and UV radiation, causing oxidation, cracking, and surface breakdown. EPDM's saturated polymer backbone is inert to these attack mechanisms — it simply does not degrade under outdoor conditions the same way.

This is not a marginal difference. SBR installed outdoors in the UK climate will typically show visible cracking and brittleness within 18-24 months. EPDM in the same location will still be performing at full specification after 20 years.

✅ Advantages

  • UV resistant: Does not degrade in sunlight — ever
  • Weather resistant: Handles rain, frost, ozone, heat
  • Extreme temperature range: -40°C to +120°C
  • Full colour range: Vibrant colours that remain stable for decades
  • Long outdoor lifespan: 15-25 years typical
  • BS EN 1177 compliant: Standard for playground safety
  • Low maintenance: Wash down with water, no special treatments

❌ Disadvantages

  • Higher cost: 30-50% more per m² than SBR
  • No oil resistance: Not for hydrocarbon environments
  • Slightly softer: Less abrasion resistance than SBR under very heavy loads
  • Specialist installation: Wet-pour systems require professional laying

EPDM Playground Safety Surfacing

The UK's playgrounds use EPDM in two main forms:

  • Wet-pour rubber: EPDM granules bound with polyurethane binder, poured in-situ. Creates a seamless, fully compliant surface with certified critical fall heights up to 3m+.
  • EPDM rubber tiles: Pre-manufactured tiles for easier installation and replacement. Suitable for school playgrounds, parks, nurseries.

Both forms are tested and certified to BS EN 1177 (Impact Absorbing Playground Surfacing). See our BS EN 1177 Playground Range →

EPDM for Rooftop & Terrace Applications

Commercial and residential rooftop terraces increasingly specify EPDM tiles for foot traffic areas. The combination of UV stability, drainage performance, and temperature resistance makes EPDM ideal where SBR would be structurally unsafe. Typical thickness: 20mm–40mm tiles with drainage profiles.

Natural Rubber (NR)

Natural rubber is harvested from the latex of Hevea brasiliensis trees, primarily in Southeast Asia. It remains the benchmark for elasticity and tear resistance — properties that synthetic rubbers approximate but rarely match. In the UK flooring market, Natural Rubber's stronghold is equestrian and premium gym applications where pure performance justifies the higher cost.

✅ Advantages

  • Superior elasticity: Returns to shape better than any synthetic
  • Excellent tear resistance: Extremely difficult to puncture or rip
  • High resilience: Absorbs and returns energy — ideal for shock absorption
  • Good low-temperature flexibility: Stays pliable in cold stables
  • Premium performance: The professional's choice for demanding applications

❌ Disadvantages

  • UV degradation: Like SBR, fails outdoors
  • Not oil-resistant: Hydrocarbons cause swelling
  • Ozone susceptibility: Surface cracking in ozone-rich environments
  • Higher cost than SBR: Premium pricing reflects raw material quality
  • Latex allergies: Very rare but worth checking in sensitive environments

Natural Rubber for Horse Stable Mats

In equestrian applications, Natural Rubber's elasticity translates directly into horse welfare outcomes. Horses spend 20+ hours per day standing on stable mats — the resilience and cushioning of natural rubber significantly reduces leg fatigue, joint stress, and risk of injury. Our stable mat range uses high-grade natural or SBR/NR blends to deliver both welfare and value.

Nitrile Rubber (NBR) — When You Need Oil Resistance

If your environment involves oils, fuels, greases, or hydraulic fluids, none of SBR, EPDM, or Natural Rubber will work. You need Nitrile Rubber (NBR).

✅ When to Specify Nitrile

  • Automotive garages and service pits
  • Engineering workshops with cutting oils
  • Industrial food processing areas (oil/grease contact)
  • Aviation maintenance facilities
  • Petrol station forecourts
  • Marine engine rooms

Key property: Acrylonitrile content (18-50%) determines oil resistance. Higher ACN = better oil resistance but reduced flexibility at low temperatures.

⚠️ Common Mistake: Specifying "rubber matting" for a garage workshop without checking chemical resistance. Standard SBR, EPDM, and Natural Rubber will swell, soften, and fail rapidly in oil/fuel environments. Always check the product data sheet for chemical resistance and specify Nitrile (NBR) explicitly for oil-contact applications.

Cost Comparison: SBR vs EPDM vs Natural Rubber (UK, 2026)

Prices vary by thickness, format (roll vs tile), and order quantity. These are indicative ranges for commercial-grade material.

Type Format Typical Price Range Notes
SBR 8mm tiles (1m²) £8–£15/m² Most economical indoor option
SBR 15mm tiles (1m²) £18–£28/m² Gym/weightlifting spec
SBR Rolls (per m²) £6–£14/m² Best value for large areas
EPDM 20mm tiles (1m²) £22–£40/m² Outdoor certified
EPDM Wet-pour (installed) £35–£80/m² Includes installation & binder
Natural Rubber Stable mats (17mm) £25–£45/m² Equestrian spec, high elasticity
Nitrile (NBR) Sheet (per m²) £30–£60/m² Oil-resistance premium
💡 Whole-life cost matters: EPDM costs 2-3× more than SBR upfront for outdoor use — but SBR will need replacing every 2-3 years outdoors, while EPDM lasts 15-25 years. Over 20 years, EPDM is dramatically cheaper per year of service life.

Installation: Key Differences Between Rubber Types

Rubber type affects how a product should be installed, maintained, and joined.

SBR — Installation Notes

  • Heavy rolls can be dry-laid (no adhesive needed for gym areas — weight holds them)
  • Tiles can be interlocking (puzzle edge) or straight-edge with adhesive
  • Acclimatise for 24 hours before installation (especially in cold weather)
  • Use contact adhesive for permanent bonded installations
  • Allow 5mm expansion gap around perimeter
  • Clean subfloor thoroughly — dust or debris under rubber causes premature wear

EPDM — Installation Notes

  • Tiles: typically dry-laid or bonded with specialist adhesive
  • Wet-pour: requires professional installation (mixing, pouring, levelling is critical)
  • Seams must be sealed in outdoor applications to prevent water ingress under the surface
  • Slope and drainage design are critical for outdoor EPDM installations
  • Allow full cure time (72 hours min) before opening to traffic

Natural Rubber Stable Mats — Installation Notes

  • Heavy mats (typically 15-17mm) are dry-laid — weight provides stability
  • Interlock with adjacent mats to eliminate gaps (trip hazard, bedding ingress)
  • Stable floor should be level and compacted before laying
  • Clean with mild disinfectant — avoid petroleum-based cleaners

Frequently Asked Questions

What is the difference between EPDM and SBR rubber flooring?
SBR is a cost-effective synthetic rubber best suited for indoor applications — gyms, warehouses, workshops. It has excellent abrasion resistance but degrades in UV light within 2-3 years outdoors. EPDM is engineered specifically for outdoor use — it resists UV rays, ozone, and temperatures from -40°C to +120°C, lasting 15-25 years outside. EPDM costs 30-50% more than SBR but is the only correct choice for permanent outdoor installations.
Can I use SBR rubber flooring outdoors?
SBR can be used outdoors temporarily (1-2 years), but UV radiation will cause it to crack, fade, and degrade. For any permanent outdoor installation — playgrounds, terraces, pool surrounds, outdoor gyms — you must use EPDM. Using SBR outdoors long-term is a false economy: the cost saving is wiped out by early replacement costs.
Which rubber type is best for horse stable mats?
Natural Rubber (NR) is the premium choice for horse stables — it offers superior elasticity, cushioning, and resilience that keeps horses comfortable during long periods of standing. High-grade SBR is the budget alternative for stable mats and performs adequately for most equestrian applications. EPDM is generally not used for stable matting as its primary advantage (UV resistance) is not relevant in covered stables.
What rubber is used for playground safety surfacing?
EPDM rubber is the standard for playground safety surfacing. It withstands outdoor weather year-round, maintains its colour, and meets BS EN 1177 critical fall height requirements. The coloured EPDM granule layer is always the surface material — SBR may be used as the base layer beneath for structural support but would not be specified as the exposed surface outdoors.
Why does new rubber flooring smell and is it safe?
New rubber flooring — especially SBR — releases volatile organic compounds (VOCs) which create a distinctive rubber smell. This is harmless and dissipates within 2-4 weeks with proper ventilation. EPDM generally has significantly less odour than SBR. Natural Rubber has a mild, earthy scent. None of these rubber types are toxic; the VOCs are well below safety thresholds. To speed dissipation: ventilate well, use a fan, and mop with diluted white vinegar.
How long does rubber flooring last?
Lifespan depends on rubber type and environment: SBR indoors lasts 10-20 years under normal commercial use. SBR outdoors lasts only 2-3 years before UV degradation. EPDM outdoors lasts 15-25 years — it's engineered for long outdoor life. Natural Rubber in stable or equestrian use: 8-15 years depending on load and cleaning routine. Nitrile (NBR) in chemical environments: 5-15 years depending on exposure concentration.
Is recycled rubber flooring as good as virgin rubber?
For most applications, yes. Recycled rubber flooring (crumb rubber from used tyres) is SBR-based and offers comparable abrasion resistance, density, and durability to virgin SBR. The environmental benefit is significant — diverting tyres from landfill. The main practical difference is slightly more odour when new, and colour options are limited to black or dark grey. For colour-specific applications or premium equestrian use, virgin rubber is preferable.
Which rubber type resists oil and chemicals?
None of SBR, EPDM, or Natural Rubber offer good oil resistance. For automotive workshops, engineering environments, or anywhere with fuel, oils, or greases, you need Nitrile Rubber (NBR). NBR is specifically formulated with acrylonitrile to resist hydrocarbons. EPDM has moderate resistance to dilute acids and alkalis but is not suitable for hydrocarbon environments. Always specify Nitrile explicitly when oil resistance is a requirement.
