Performance & Application:

● L-XNBR is a liquid rubber product with a main chain containing nitrile and carboxyl. Nitrile can provide good solvent resistance, heat resistance, wear resistance and adhesive properties, while carboxyl can react and cure with epoxy, amino and other groups.

● It can be used as a toughening modifier for epoxy and phenolic resins, as well as a plasticizer and softener for rubber, and can be applied in fields such as printing rollers, sealing rings, coatings and adhesives.
