Hydroxyl-terminated Polybutadiene

Introduction   Mainly used in potting compound and adhesive for electric element, it is a kind of liquid telechelic polymer, and has super low-temperature resistance and flexibility.

       HTPB is a kind of telechelic polymer, and  a new type of liquid rubber. It can be formed a 3D network structure solid through react to the chain extender and cross linker at normal or high temperature. It equip with excellent mechanical performance, and the resistance to hydrolyzation, acid and alkali, wear, low temperature, and also electric isolation.

     Usage   HTPB has good transparence, low viscidity, aging resistance, low temperature performance and good process capability. It can be used  to produce casting elastomer which is the material of  tyer of car and plane, also can be used as the material of building, shoes-making, rubber  products, insulating products, dope, adhesive, casting , insulation , waterproof, racetrack, wearable transfer belt, and also can be used to modify rubber and epoxy resin.
