Nipol® and Sivic Polyblends and Pre-Plasticized Nitrile Elastomers

Nipol Polyblends are used where toughness and ozone resistance is required. The PVC content of the polymer imparts fuel, ozone, permeation and abrasion resistance.

Nipol Pre-Plasticized Elastomers are used in soft roll compounds where high oil loadings are needed to have materials in the 20 to 30 Shore A Hardness range.
