Nitrile Gasket & Buna n Seal & NBR Gasket
Nitrile Gasket, also called Buna N Gasket & NBR Rubber Gasket & Nitrile Butadiene Rubber Gasket, known as oil-proof NBR O-ring & Seal, is made from Butadiene and Acrylonitrile through emulsion polymerization method, molded by rubber compression & injection & extrusion molding & die-cutting toolings.
Nitrile Gasket & Buna N Seal Properties:
1. Excellent Oil Resistance, better than natural rubber (NR), neoprene rubber (CR), styrene butadiene rubber SBR, rank only second to Flurorubber & Viton (FKM FPM), polysulfide rubber, Acrylic Rubber (ACM).
2. Good wear resistance and high tensile strength: can be used for oil resistance rubber sealing gasket & O-ring
3. Good anti-static property and air tightness
4. Strong adhesion
5. Good compatibility with polar materials like PVC, POM, Nylon etc. it can be made into polymer (plastic+rubber) materials.
6. Poor resistance to Ozone, sunlight & weather, not good for outside productions
7. Can't be at exposure of aromatic solvents, halogenated hydrocarbon solvents ad ketones & esters solvents.
