Thermosets and Elastomers
Neoprene
Neoprene (Polychloroprene) has the advantages of good resistance to flame, weather, ozone, abrasion, flex cracking, alkalis and acids, with moderate resistance to oil and gasoline. We inventory military specification grades of neoprene in 40, 50 and 60 durometer certified to Mil-R-6855 Class 2. We also inventory high-grade commercial grade neoprenes, with 100% neoprene content for predictable performance in harsh environmental applications, and lower cost commercial grade neoprenes with 51% neoprene content when gaskets will not be exposed to chemical environments. Uncured compounds in 30, 40, 50, 60 and 70 durometer shore A are inventoried to support our fast-turn sheet molding capability.
Reinforced Viton
Nitrile
Nitrile (Buna-N) is primarily used for applications requiring petroleum oil and gasoline resistance, but not intended for sunlight exposure. We inventory military specification grades of Buna-N in 40 and 60 durometer certified to Mil-R-6855 Class 1.
Viton®
Fluoroelastomer (Viton®) or fluorocarbon rubber withstands high temperatures in conjunction with aggressive chemicals, fuels and lubricants, along with resisting flame propagation, ozone and weather. However, fluorocarbon rubbers are severely attacked by highly polar fluids such as ketones, hydrazine, anhydrous ammonia and Skydrol (phosphate ester) hydraulic fluids. Post curing is required to achieve optimum properties. We inventory a high quality grade 70 and 80 durometer Viton® sheet, and a 75 durometer specification grade certified to Mil-R-83248C, Type 2, Class 1.
Polycraft Products die cuts solid sheet rubber materials into gaskets, and water jet cut gaskets to customer specifications. Water jet cutting of solid rubber gasket materials from .015" to 1.0" thick can be done quickly from your dxf or dwg file.
Special sheet rubber gauges and compounds can be molded from our 12" x 12" and 14" x 14" sheet molds. The combined versatility of die cutting, water jet cutting and custom molding is rarely found in one rubber gasket manufacturer.
