HTBS is a low molecular telechelic polymer which has butadiene- styrene as its main chain, and active function group at both ends. This type of liquid latex which has the performance of solid butadiene-styrene rubber, is the material of casting and sealing for the function group reaction to extend the molecular chain and come into high polymer. For the good performance of insulation and wearproof, the HTBS can be used in the processing field which the solid butadiene-styrene rubber is unsatisfied.
