SBS+SEBS

WR Series | High-Durability White Thermoplastic Elastomers (TPEs)

The WR Series High-Durability White Thermoplastic Elastomer (TPE) is formulated based on an SBS elastomer system and is specifically engineered for applications demanding high resistance to tearing, abrasion, and mechanical stress.
Designed for industrial and high-durability consumer products, the WR Series emphasizes structural stability, durability, and long-term reliability, distinguishing itself from conventional soft-touch TPE materials.
It effectively reduces the risk of product failure caused by fatigue or stress concentration during real-world use.
