Hydroxy-terminated Nitrile Butadiene Rubber (HTBN)

Performance & Application:

● HTBN is a liquid nitrile butadiene rubber with hydroxyl functional groups at both ends of the molecular chain. It has the same physical and chemical properties as nitrile butadiene rubber, can be cured with isocyanate curing agent, and has good reactivity and processing properties.

● It possesses good oil resistance, heat resistance, wear resistance and strong adhesion.

● Mainly used in adhesives, coatings, resin toughening agents, can enhance the toughness of composite materials, adhesion and durability, oil resistance and heat resistance.
