Hydrogenated HTPB CAS 69102-90-5 Hydrogenated Hydroxyl Group-Terminated Polybutadiene

2024-04-10

HTPB is a liquid remote claw polymer, the new liquid rubber. The properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers’ specific requirements. A typical HTPB is R-45M with each end of the chain terminated with a hydroxyl [OH] group. meanwhile we can do new design as the HTPB with a single -OH per chain and Hydrogenated version.


For Hydrogenated HTPB (Hydrogenated Hydroxyl Group-Terminated Polybutadiene/ Hydrogenated Hydroxyl Terminated Polybutadiene(HTPB) is hydrogenated homopolymers of butadiene,

they are both-end hydroxyl group-terminated and suitable for a wide range of uses. Due to the saturation of 1,2-vinyl group these polybutadienes possess excellent long-term chemical stability.

with the Properties as:

1. Highly flexible structure


2.Hydrophobicity


3.Low dielectric constant


4.Good chemical resistance


5.Reactive hydroxyl groups


6.Long-term stability


can be used as resin modifiers, urethane resins(paints, adhesives, coating agents), electrical insulating materials, TPU elastomers


our Hydrogenated HTPB specification as follow (in addition: We can research and develop any new version of HTPB according to the special demand of our clients)
