Product Description

EHTPB is HTPB molecular chain that introduces epoxy groups, which has advantages such as oil resistance, aging resistance, good transparency, and good low-temperature performance. The hydroxyl groups at the end of the molecular chain and the hydroxyl groups in the molecular chain
The epoxy group is a reactive group that can be cured with various isocyanates and epoxy curing agents

The cured polymer has good physical and chemical properties, excellent adhesion strength to various non-metallic materials such as metals and glass, good dielectric properties, low shrinkage rate, and hardness
High degree, stable to alkali and most volumes, can significantly improve the mechanical properties, adhesive strength, and heat resistance of polyurethane materials


The EHTPB can be used for adhesives, sealants, coatings, epoxy resin toughening, polyurethane elastomers, etc.

Packing & Storage

Packed in 50kg/drum, 170kg/drum, The storage period is 1 year.

Safety instructions:

Storage should be at cool, dry and ventilate. The best condition is among -20 ~ 38℃. Shelf life of 12 months, if expire, still used if up to standard through retest. When transportation should avoid rain, sunlight. Don’t mix with strong oxidizer.
