NBR latex is latex made by emulsion polymerization of butadiene and acrylonitrile. Acrylonitrile can be divided into high nitrile (35%~45%), medium nitrile (25%~33%) and low nitrile (20%~25%). The latex has uniform molecular weight and particle size distribution, oil resistance, solvent resistance, acid and alkali resistance, cross-linking with sulfur and metal oxides, and its stability is better than that of natural latex.
