Kuraray HYBRAR™

What is HYBRAR?

HYBRAR is a high-performance thermoplastic rubber that exhibits superior vibration dampening properties as well as excellent clarity when blended with polypropylene. HYBRAR has vinyl branching in the midblock, which gives it vibration-dampening properties at normal-use temperatures. It is commonly used in medical bags and tubing, sporting goods, automotive products, and construction.
