Liquid Rubber-Random Carboxy Nitrile Butadiene Rubber (L-XNBR)
Properties and Uses
L-XNBR is a liquid rubber product containing nitrile and carboxyl groups in the main chain. The nitrile group can provide good solvent, heat, abrasion and adhesive properties, while the carboxyl group can react with epoxy and amino groups for curing.
It can be used as a toughening modifier for epoxy and phenolic resins as well as a softening agent for rubber plasticizing, and is used in the fields of printing rollers, seals, coatings and adhesives.
