NV-512 A high-density cellulose fiber-reinforced material with a Fully Cured nitrile binder. High tensile strength, low compressibility and high recovery contribute to torque retention and stress relaxation. Designed for heavy-duty applications where resistance to crushing and extrusion is required including air pumps, carburetors, diaphragm base materials, differential housings, fuel filler necks, pipe Ranges, speed reducers, transmissions For applications up to 180°C (350° F). 0.96 (60) 10-20 60 20.7 (3000) 10 30 - - 15 65 40 80 Fully Cured
Nitrile Butadiene
NV-565 Medium-density cellulose-reinforced gasket material comprised of a unique blend of elastomers which combine the oil and water resistance of nitrile latex in a styrene and nitrile butadiene binder. Excellent fuel performance for carburetor applications. Excellent wicking resistance, conformability to irregular flange surfaces for applications such as carburetors, engine front covers, fuel systems, water pumps. For applications up to 180°C (350° F). 0.64 (40) 40 40 12.1 (1750) 10 65 - - 15 65 40 80 Styrene and
Nitrile Butadiene
SV-360 Medium-density economical material formulated of cellulose fibers and a styrene butadiene binder. Dimensionally stable and conformable to irregular flanges A general purpose material for anti-squeak, dust seals, heaters, oil seals, shim stock, thermostats, water pumps. For applications up to 180°C (350° F). 0.67 (42) 40 40 10.4 (1500) 15 70 - - 15 70 55 80 Styrene Butadiene
2331 Environmentally compatible low-density material formulated from recycled gasket materials Processed with proprietary recycling technology for general light duty sealing applications Styrene butadiene binder. For applications up to 180°C (350° F). 0.56 (35) 15-35 35 6.9 (1000) 15 80 - - 15 80 55 80 Styrene Butadiene
