EPDM Running Track Product Data Sheet
Product Introduction
EPDM Running Track is an environmentally friendly sports surface system composed of EPDM (Ethylene Propylene Diene Monomer) rubber granules mixed with polyurethane (PU) binder, either site-installed or prefabricated. Due to its excellent weather resistance, aging resistance, and color stability, EPDM material is an ideal choice for schools, stadiums, fitness trails, and similar venues. The product typically features a two-layer structure: a base cushion layer of black SBR rubber granules mixed with PU binder, and a top wear layer of colored EPDM granules mixed with PU binder for abrasion resistance and slip prevention.
Performance Characteristics
· Excellent Weather Resistance: EPDM material offers outstanding UV resistance, ozone resistance, and aging resistance, maintaining color stability without cracking during long-term use
· Eco-Friendly & Non-Toxic: Made from virgin EPDM granules, free from harmful substances found in recycled rubber, passing REACH, RoHS, and other environmental certifications
· Optimal Elasticity: Excellent shock absorption performance, effectively protecting athletes' joints and reducing injury risk
· Slip-Resistant Safety: Moderate friction coefficient maintains good anti-slip performance under both dry and wet conditions
· Rich Color Options: Customizable in multiple colors (red, green, blue, yellow, orange, etc.) to meet various design requirements
· Permeable Design: Porous structure allows rapid water infiltration, preventing water accumulation and enabling immediate use after rain
· Long Durability: Service life of 10-15 years under normal usage conditions
· Low Maintenance: Dense surface, easy to clean, minimal daily maintenance costs
Scope of Application
· School Sports Fields: Primary, middle school, and university athletics tracks, playgrounds, recess activity areas
· Professional Training Facilities: Sports centers, athletics training grounds, sports school venues
· Public Fitness Areas: Community fitness trails, park jogging paths, leisure greenways
· Kindergarten Activity Areas: Children's play areas, safety surfacing
· Sports Venues: Indoor/outdoor athletics halls, multi-purpose stadiums
· Military Training Grounds: Physical training areas, obstacle courses
