Hydroxyl-terminated Polybutadiene(HTPB)
一、Characteristic:
Hydroxyl Terminated Polybutadiene is most commonly used by reacting with isocyanates to produce polyurethanes with : 1.)excellent hydrolysis resistance 2.)superior mechanical properties 3.)particularly low temperature flexibility 4.)excellent electrical insulation 5.)excellent chemical resistance to mineral acids and bases.
二、 Usage:
1）HTPB can be used as rubber modifier, reaction & injection, typecasting.
2）HTPB can be used to produce all kinds of adhesive, sealant, coatings.
3）HTPB can be used in Electrical and electronic industry as Potting compounds for protection of telecommunication cables in junction boxes Component encapsulation Elastomeric coatings
4）HTPB can be used in construction industry as Impermeable sealants for double glazing. Flexible coatings Impermeable coatings and joint sealants Bitumen extended elastomers Coatings of tanks in the chemical industry.
