Modern sports flooring systems require a combination of safety, durability, athletic performance, and cost efficiency. Among the materials used in running tracks and sports surfaces, SBR and EPDM rubber granules are the most common choices.
Although both materials provide elasticity and shock absorption, they serve different functions within a sports flooring system and offer distinct performance characteristics.
SBR (Styrene Butadiene Rubber) granules are primarily produced from recycled truck and passenger vehicle tires.
Key characteristics include:
Excellent shock absorption
High resilience
Cost-effective solution
Sustainable recycling material
Ideal for large-area installations
SBR granules are commonly used as the base shock-absorbing layer of running tracks and sports flooring systems.
EPDM (Ethylene Propylene Diene Monomer) granules are manufactured from virgin synthetic rubber.
Key advantages include:
Superior UV resistance
Outstanding weather resistance
Long-lasting color stability
Excellent durability
Extended service life
EPDM granules are typically used as the top wear layer of running tracks and recreational surfaces.
A standard running track generally consists of:
Asphalt or concrete foundation
SBR granules mixed with PU binder
Functions:
Impact absorption
Energy return
Injury reduction
Colored EPDM granules mixed with PU binder
Functions:
Surface durability
Slip resistance
Athletic performance
Aesthetic appearance
This structure provides an ideal balance between performance and cost.
SBR effectively reduces impact forces on joints and muscles.
SBR is significantly more economical than virgin rubber materials.
Manufactured from recycled tires, SBR supports circular economy initiatives.
SBR performs consistently when combined with polyurethane binders.
EPDM maintains performance under sunlight, rain, heat, and cold.
Unlike many recycled materials, EPDM retains its original color for years.
Ideal for high-traffic sports facilities.
Provides a comfortable, slip-resistant surface for athletes.
| Feature | SBR Granules | EPDM Granules |
|---|---|---|
| Raw Material | Recycled tires | Virgin synthetic rubber |
| Color Options | Mostly black | Multiple colors |
| UV Resistance | Moderate | Excellent |
| Weather Resistance | Good | Excellent |
| Wear Resistance | Good | Excellent |
| Shock Absorption | Excellent | Excellent |
| Service Life | 5–8 years | 8–15 years |
| Cost | Lower | Higher |
| Typical Use | Base layer | Top layer |
Both EPDM and SBR rubber granules play essential roles in modern sports flooring systems.
SBR granules provide cost-effective shock absorption and resilience, making them ideal for the base layer. EPDM granules deliver superior durability, color stability, and weather resistance, making them the preferred top-layer material.
For most running tracks, schools, sports facilities, and community recreation projects, the combination of an SBR base layer and an EPDM wear layer offers the best balance of performance, durability, safety, and cost-effectiveness.
