HTBS Hydroxyl-Terminated Polybutadiene(HTPB)-styrene copolymer/HTBS
HTBS is a liquid copolymer of butadiene and styrene with hydroxyl functional groups at the end of the molecular chain, which has excellent heat resistance, wear resistance, aging resistance, and processing performance
Good, low heat generation, good flexibility at low temperatures
HTBS can be used in combination with natural rubber and synthetic rubber, and can also be used separately for pouring polyurethane tires, potting compounds, adhesives, etc.
It has excellent traction performance and wear resistance when used for tread rubber.
Packed in 50kg/drum, 170kg/drum, The storage period is 1 year.
Safety instructions:
Storage should be at cool, dry and ventilate. The best condition is among -20 ~ 38℃. Shelf life of 12 months, if expire, still used if up to standard through retest. When transportation should avoid rain, sunlight. Don’t mix with strong oxidizer.
