XNBR 70 Carboxylated Nitrile Food Grade Compound

XNBR 70 Carboxylated Nitrile Food Grade Compound

Carboxylated Nitrile (XNBR) is a special type of nitrile polymer that exhibits enhanced tear and abrasion resistance while retaining excellent oil and solvent resistance.



XNBR compounds also provide high tensile strength and good physical properties at high temperatures.

This grade is also available in White and Grey colours
