What Standards Define High-Quality EPDM Granules for Running Tracks?
A high-performance running track starts with premium EPDM rubber granules.
To ensure safety, durability, and athletic performance, EPDM granules must meet strict international standards for elasticity, weather resistance, tensile strength, and environmental safety.
As a professional EPDM manufacturer, our products not only meet these benchmarks but consistently exceed them, delivering superior quality for school, stadium, and community tracks.
Core Standards for High-Quality EPDM Running Track Granules
1. Elasticity & Shock Absorption (Critical for Athlete Safety)• Compression recovery rate ≥ 90%
• Springback value ≥ 20mm
• Hardness: 30–50 Shore A
Elasticity ensures the track cushions impact, reducing strain on athletes’ knees and joints.
A high compression recovery rate means the surface quickly regains its shape after use, preventing permanent deformation.
2. Tensile Strength & Durability (Resists Wear & Tearing)
• Tensile strength ≥ 0.5 MPa
• Tensile elongation ≥ 90%
These metrics measure the EPDM’s resistance to breaking or cracking under tension—critical for withstanding heavy foot traffic, extreme weather, and long-term use.
• UV-stabilized to prevent fading
• Anti-aging properties to avoid cracking in heat/cold
Outdoor tracks face constant sun, rain, and temperature changes. Quality EPDM must maintain color and performance for 10+ years.
4. Environmental & Safety Compliance (Non-Toxic & Eco-Friendly)
• Meets REACH, RoHS, and GB standards
• Non-toxic, odorless, and free of heavy metals
Safe for students, athletes, and the environment—non-negotiable for public spaces.
5. Flame Retardancy (Enhanced Public Safety)
• Flame retardant level ≥ Class I
Prevents combustion and reduces fire risk in high-traffic areas.
How Our Factory’s EPDM Granules Exceed These Standards
We pride ourselves on producing EPDM granules that outperform industry benchmarks in every category:1. Superior Elasticity & Shock Absorption
• Compression recovery rate: 98.5% (vs. standard 90%)
• Springback value: 26mm (vs. standard 20mm)
• Hardness: 47 Shore A (optimal within 30–50 range)
Our granules offer unmatched cushioning, reducing injury risk and enhancing athletic performance.
2. Exceptional Tensile Strength & Durability
• Tensile strength: 1.74 MPa (3.5x the standard 0.5 MPa)
• Tensile elongation: 103.6% (vs. standard 90%)
Resists tearing, cracking, and deformation—even in high-traffic stadiums.
3. Industry-Leading Weather Resistance
Our EPDM uses advanced UV stabilizers and anti-aging additives, maintaining color and elasticity for 15+ years—5 years longer than the standard lifespan.
4. Strict Environmental Compliance
We exceed REACH and RoHS standards with 100% non-toxic, recycled materials. Our granules are odorless and safe for children and athletes.
5. Top-Tier Flame Retardancy
Achieves Class I flame retardancy (meets and exceeds the standard), ensuring maximum safety for public tracks.
