Trade Names: Neoprene (E.l. duPont), Butachlor (Ditsugil), Bayprene (Mobay)
Moderately resistant to petroleum products. Good Ozone and weather resistance. Good compression set. Excellent for sealing refrigeration fluids such as Freon®. Temperature range -65° F to +250° F.
Neoprene gasket material comes in four primary forms; closed cell (wet suit material), open cell, diaphragm, and homogeneous. Each of these three types have styles, colors and density variations that make them unique gasket materials.
Style 0725 - 60 Duro Neoprene blend provides moderate resistance to oil and ozone. For use in bumpers, pads, and sealing in general gasket and flange applications.
Minimum tensile strength - 800 PSI. Durometer 60+/-5. Temperature range: - 20°F to +170° F. Black color.
Style 0725S - 40 Duro Neoprene blend provides moderate resistance to oil and ozone. For use in bumpers, pads, and sealing in general gasket and flange applications.
Style 0725H - 70 Duro Neoprene blend provides moderate resistance to oil and ozone. For use in bumpers, pads, and sealing in general gasket and flange applications.
Style 0734 - 70 Duro Cloth Finish - Good resistance to Sunlight, and outdoor weathering. Performs well in contact with many oils and chemicals. Cloth Finish. Durometer 70 +/-5. Tensile strength 1000 PSI. Elongation 200%. Temperature Range -30° F to +200° F
STYLE R-451 / R431 Black Closed Cell Sponge
Black neoprene closed cell (expanded) sponge gasket sheet. Tiny individual sealed
cells contain inert nitrogen gas to resist moisture, dirt and air even at cut edges. It is this unique structure that makes the closed cell sheet an insulator, sound and vibration damper and shock absorber. Compression deflection 5-13 PSI. Density 15-30 lbs/cubic foot. Water absorption 5% maximum. Temperature range -30°F to +150°F (continuous) (to 200°F intermittent). Tensile strength 150 PSI. Elongation 350%.
STYLE 0741 Neoprene Duck Inserted Diaphragm Gasket Material
Oil-resistant neoprene diaphragm material designed transmit pulsations between gases, air, and fluids. Reinforced with cotton duck to provide structural Strength. Durometer 70+/-5. Tensile strength 1500 PSI. Elongation 300%. Temperature range -40°F to 220°F Smooth finish.
The properties of Neoprene are often desired in applications that have pressure over 125 psig. Homogeneous Neoprene is fine between flanges for low pressure but for higher pressure applications manufacturers such as Durlon, Garlock, Thermoseal and FMI have created neoprene based materials that include Aramid fiber, Fiberglass, Carbon/Graphite or Mineral Fiber to give the gasket material strength. American Seal and Packing stocks and cuts many of these materials and can provide custom gaskets to your door.
