Description
AT Red Vulcanized Fiber Insulation Die-cut Gasket is designed for electrical insulation, heat insulation, sealing, corrosion protection, and custom die-cut gasket applications. Made from red vulcanized fiber paper based on cotton pulp / wood pulp insulating material, it provides good mechanical strength, dielectric strength, toughness, smooth surface quality, and water absorption performance. The material can be supplied as plain insulation gasket parts or with optional acrylic pressure-sensitive adhesive when positioning support is required. AxisTape can process this vulcanized fiber material into washers, pads, spacers, liners, holes, strips, and custom die-cut insulation components according to customer drawings or samples.
