ETPU

ETPU is a next-generation high-performance elastomer, engineered specifically for athletic tracks, sports courts, and high-traffic recreational surfaces — delivering a stable, resilient foundation.

Product Advantages

Lighter:

Bulk density of just 0.9–1.0 g/cm³ — 15–20% lighter than conventional base granules. Achieve the same performance with less material, reducing installation costs.

More Elastic

Delivers a “spring-like” effect with >65% rebound resilience, providing uniform support for the top layer while effectively absorbing impact — meeting European HIC (Head Injury Criterion) safety requirements.

Safer

Ensures flexibility and reduces the risk of cracking or athlete injuries.
