Hydroxyl Terminated Poly butadiene™ (hydroxyl-terminated liquid polybutadiene)

good rubber elasticity
It has approximately 80% 1,4 bonds, making it an excellent rubber elastic material.

Excellent cold resistance
It has excellent cold resistance as the embrittlement temperature of the cured product is below -70℃.

Exceptional water resistance
Since the main chain does not contain ether or ester, it has excellent water and chemical resistance.

Effective reinforcement and oil spreading possible
Reinforcement/increase with carbon black, various fillers, and oil expansion with process oil, asphalt, etc. are possible.

Excellent electrical properties
It has electrical insulation and dielectric properties comparable to those of epoxy resin and silicone rubber, and is characterized by low temperature dependence. Furthermore, it has low moisture permeability, low water absorption, and low thermal stress, so it can withstand thermal cycle tests (-55℃ to +130℃).

Excellent workability
Since it is a liquid, it is easy to process and can be easily mechanized, automated, and continuous, and it can be cast and processed on-site without sacrificing the elasticity and strength of rubber, increasing work efficiency. Taking advantage of these features, it is used in a variety of fields as a new rubber elastic material that can replace conventional ether-based polyurethane, ester-based polyurethane, silicone, epoxy, etc.
