Kuraray KURARITY™

KURARITY is Kuraray’s latest innovation in thermoplastic elastomers. Tri-block and di-block acrylic-based polymers offer maximum transparency, flexibility, and adhesion. They can be extruded into a wide variety of applications, such as film or profiles. Alternatively, KURARITY can be used as an additive to improve compatibility or modify polar plastics.

LIR

Kuraray Liquid Isoprene Rubber®

Kuraray Liquid Isoprene Rubber (LIR) is a viscous rubber additive that is used in kneading and cross-linking rubber when shaping and processing. LIR works as a reactive plasticizer and can replace the natural mineral oil present in rubber, reducing oozing and spoiling in the shaping and molding process.

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.
