What Is SBR Rubber? UK Guide to Styrene-Butadiene Rubber 2026
What Is SBR Rubber?
SBR (Styrene-Butadiene Rubber) is a synthetic rubber made from a copolymer of styrene and butadiene monomers. It is the most widely used synthetic rubber in the world, accounting for around 25% of global rubber production. In UK flooring applications, SBR is most commonly produced by recycling and re-vulcanising used vehicle tyres — making it the primary material in rubber gym flooring, stable mats, and commercial rubber matting. It offers excellent durability, abrasion resistance and value for indoor use.
SBR Rubber Key Properties
| Property | SBR Rubber Performance |
|---|---|
| Abrasion resistance | Excellent — superior to natural rubber |
| UV resistance | Poor — degrades outdoors; indoor use only |
| Oil resistance | Poor — not suitable for oil/fuel environments |
| Water resistance | Good for liquid water |
| Temperature range | -40°C to +100°C continuous service |
| Shore A hardness | 45–75 depending on formulation |
| Colour | Black (carbon black reinforcement) |
| Cost | Lowest cost rubber for flooring |
| Eco credentials | Up to 100% recycled tyre content |
SBR vs EPDM Rubber: Which Should You Choose?
| Property | SBR Rubber | EPDM Rubber |
|---|---|---|
| UV resistance | Poor — indoors only | Excellent — outdoor rated |
| Cost | Lower | 30–60% more expensive |
| Colour stability | Black only (coloured tops fade) | Stable, wide colour range |
| Best for | Indoor gym, stable, industrial | Outdoor, playground, premium |
| Durability indoors | Excellent (10–20 years) | Excellent (10–20+ years) |
| Recycled content | Up to 100% recycled tyre | Virgin synthetic rubber |
What Is SBR Rubber Used For?
SBR rubber is the workhorse material in UK rubber flooring:
- Gym flooring — interlocking rubber tiles, rolls and mats for home and commercial gyms
- Horse stable mats — 17mm and 22mm solid rubber mats for equestrian use
- Industrial flooring — factory floors, warehouse walkways, workshop matting
- Entrance matting — anti-slip entrance and scraper matting
- Anti-fatigue mats — ergonomic standing mats for workplaces
- Vehicle flooring — van and horsebox rubber flooring
- Anti-vibration matting — machinery isolation pads
Is SBR Rubber Safe for Indoor Use?
Yes — SBR rubber is safe for normal indoor use. The material is non-toxic in solid form and is approved for sports facilities, equestrian environments and commercial workplaces. One consideration: carbon black from recycled SBR can transfer to skin in direct prolonged contact. For barefoot areas (yoga studios, children's play areas) or food-safe environments, specify EPDM or virgin rubber. For gym use with shoes — no concern.
Can SBR Rubber Be Used Outdoors?
No. SBR has poor UV and ozone resistance and will crack, fade and lose structural integrity outdoors within 1–3 years. For any outdoor rubber flooring — playgrounds, patios, outdoor gyms, exposed entrance areas — always specify EPDM rubber, which is UV-stable and designed for permanent outdoor exposure.
How Is SBR Rubber Made for Flooring?
- Used vehicle tyres are collected and shredded into granules
- Metal and fibre are removed through magnetic and air separation
- Polyurethane binder is mixed with the rubber granules
- The mixture is compression-moulded in heated moulds at high pressure
- Heat cures (vulcanises) the rubber into its final form
- Quality testing: density, hardness, slip resistance and dimensional checks
Frequently Asked Questions: SBR Rubber UK
What does SBR stand for in rubber?
SBR stands for Styrene-Butadiene Rubber, referring to its two monomer components — styrene and butadiene — which are copolymerised to create the base polymer. Carbon black is added as a reinforcing filler, giving SBR its black colour and excellent mechanical properties.
Is SBR rubber the same as recycled rubber?
Not exactly — SBR is a rubber compound, and recycled SBR specifically refers to SBR recovered from used tyres (which are predominantly SBR). Virgin SBR is chemically identical but made fresh. For flooring, most SBR products use recycled tyre content, offering cost and environmental benefits.
How durable is SBR rubber flooring?
Indoors, quality SBR gym tiles and stable mats last 10–20 years with normal use. Abrasion resistance is excellent. The limitation is UV exposure — outdoors, SBR degrades rapidly. Used correctly indoors, it is one of the most durable flooring materials available.
Does SBR rubber smell?
New SBR rubber has a characteristic odour from sulphur compounds in the vulcanisation process. This is harmless and temporary, typically dissipating within 2–8 weeks with ventilation. Airing mats outdoors for 24–72 hours before installation speeds off-gassing considerably.
