Introduction
This case study showcases a full-size 400m standard synthetic running track project, completed with a striking custom purple EPDM rubber surface. Designed to meet international athletic standards while delivering a bold, modern aesthetic, the track was installed for a public sports facility seeking both durability and visual distinction.
Our ApproacH
Material Customization • Developed custom purple EPDM granules with ISO 105-B02 Grade 4-5 color fastness to maintain vibrancy under intense UV exposure • Ensured ≥20% pure EPDM polymer content for superior elasticity and impact absorption Quality Assurance • Pre-production testing for color consistency across multiple batches • Compliance with EN 71-3, REACH, and PAHs safety standards Technical Collaboration • Provided detailed mixing ratio recommendations (EPDM granules : PU binder) • Delivered on-site application guidelines and crew training support • Offered real-time troubleshooting during the laying and curing phases
WHAT WE DID
For this project, we supplied the full range of core materials and technical expertise to bring the custom purple track to life:
Premium Purple EPDM Rubber Granules
• Color-matched, UV-stabilized purple EPDM granules (1-3mm and 2-4mm blends) for the top wear layer, providing a non-slip, high-visibility surface
• Consistent particle size distribution across all batches, ensuring uniform texture, drainage, and performance
• Formulated to resist compression set, maintaining shock absorption and resilience under heavy foot trafficHigh-Performance PU Binder Adhesive
• Two-component, weather-resistant PU binder optimized for outdoor synthetic track installations
• High tensile strength and elongation properties, preventing cracking or delamination under temperature fluctuations and heavy use
• Low VOC, environmentally compliant formulation, suitable for public and educational facilitiesTechnical & Quality Assurance Services
• Provided full installation guidelines, including mixing ratios, curing times, and application techniques for the EPDM-PU system
• Conducted pre-delivery material testing (including UV resistance, tensile strength, and water absorption) to verify compliance with industry standards
• Offered post-installation support to address any technical questions, ensuring the track cured to its full performance potential
The final track surface exceeded the client’s expectations: the vibrant purple finish was uniform across all lanes, the surface passed all safety and performance tests, and the material system was installed on schedule with zero material-related delays.
