Overview

ALS Tape supplies and converts a comprehensive range of gasket materials for industrial sealing, chemical resistance, and electrical insulation requirements. Elastomeric rubbers available include nitrile for oil and fuel resistance, neoprene for acid and alkali resistance, EPDM for outdoor weathering and ozone resistance, silicone for extreme temperature service from -75°F to +500°F, Viton for aggressive chemical and high-temperature environments, polyurethane for abrasion resistance, and SBR for cost-efficient general sealing. Foam and cushioning materials include open and closed-cell foam, PORON microcellular PU, and sponge rubber for compressible sealing applications. High-performance materials include PTFE for low-friction and chemical inertness, flexible graphite for extreme temperature sealing, and cloth-inserted rubber for reinforced constructions. Electrical insulation gasket materials include Kapton polyimide, fish paper, Nomex, Mylar, and Lexan for motor, transformer, and electronics sealing applications.

FAQ

Which gasket material is best for outdoor and weathering applications?

EPDM is the standard choice for outdoor sealing due to its excellent ozone, UV, and weathering resistance. Silicone is preferred when extreme temperature cycling is also required.

Can gasket materials be supplied as precision die-cut parts?

Yes. Sheet and roll gasket materials can be precision die cut to custom shapes, with holes, slots, and complex profiles to match flange and assembly geometries.

When is PTFE selected over rubber-based gasket materials?

PTFE is selected when chemical inertness is critical — particularly in contact with aggressive solvents, acids, or oxidizing agents that degrade rubber compounds — or when very low friction is required.
