EPDM vs SBR: Key Differences in Sports Flooring Materials | Bosphorus Sport
In modern sports flooring systems, two main types of rubber materials are used: EPDM (Ethylene Propylene Diene Monomer) and SBR (Styrene Butadiene Rubber).
Both materials are elastic, flexible, and durable, but they differ in UV resistance, color stability, and cost.
At Bosphorus Sport, we select the most suitable system based on surface type, climate, and usage intensity.
As a result, every project achieves optimum performance, comfort, and long-term durability.
1️⃣ What Are EPDM and SBR?
| Material | Full Name | Key Features | Ideal Applications |
|---|---|---|---|
| EPDM | Ethylene Propylene Diene Monomer | High UV resistance, long-lasting, strong color stability | Outdoor tracks, athletics surfaces |
| SBR | Styrene Butadiene Rubber | Cost-effective, flexible, made from recycled rubber | Playgrounds, walking paths |
💡 Typically, EPDM granules are used as the top layer, while SBR is applied as the base layer.
This combination enhances both aesthetics and structural performance, ensuring consistent surface quality.
2️⃣ Technical Comparison: EPDM vs SBR
| Property | EPDM | SBR |
|---|---|---|
| UV Resistance | Very High | Low |
| Color Fading | Minimal | High |
| Elasticity | 400–600% | 250–400% |
| Hardness (Shore A) | 55–65 | 60–70 |
| Recyclability | Partial | Full |
| Cost | Higher | Lower |
EPDM pigments are evenly distributed within the material, ensuring long-term color stability.
Therefore, it performs exceptionally well in outdoor applications with high sun exposure.
Meanwhile, SBR is widely preferred in base layers due to its cost efficiency.
3️⃣ How EPDM and SBR Work Together in Layered Systems
In most professional sports surfaces, a SBR base + EPDM top combination is used.
This hybrid design balances shock absorption, durability, and aesthetic appeal.
Typical Layer Structure:
1️⃣ Concrete sub-base
2️⃣ Primer coating
3️⃣ SBR + binder mixture (base layer)
4️⃣ EPDM + binder mixture (top layer)
5️⃣ Optional UV-protective coating
This configuration ensures water resistance, optimal grip, and enhanced shock absorption.
As a result, the surface remains safe and stable for years.

Frequently Asked Questions (FAQ)
Why is EPDM more expensive?
EPDM is made from pure rubber compounds and offers superior UV resistance and durability.
Can SBR be used outdoors?
Yes, but only as a base layer, since its UV resistance is limited.
Why combine EPDM and SBR?
SBR reduces cost, while EPDM improves durability, safety, and visual quality.
