Liquid rubber-hydroxyl terminated butadiene-styrene random copolymer (HTBS)
Properties and Uses
HTBS is a liquid copolymer of butadiene and styrene with hydroxyl functional group at the end of the molecular chain, it has excellent heat resistance, abrasion resistance, aging resistance, good processing performance, low heat generation and good low temperature flexibility.
It can be used in conjunction with natural rubber and synthetic rubber, and can also be used alone for casting polyurethane tires, potting adhesive, adhesive, etc. It has excellent traction performance and abrasion resistance when used in tread rubber.
