A multitude of resin impregnated materials formed using heat and pressure producing a wide variety of product geometries. Manufacturer: n/a |
A multitude of resin impregnated materials are formed using heat and pressure into a wide variety of product geometries. The resins are generally phenolics, silicones, melamines or epoxies. The substrate materials are usually paper, woven cotton or woven glass. There is no limit to the resin matrices, the substrate materials, or the layers employed.
Grade Use Guide
Paper with phenolic grades provide low cost electrical and mechanical properties. Widely used for switchboards, panel boards, insulating washers and intricate punched parts.
Cotton with phenolic grades provide more mechanical strength than paper grades and have a finer surface with better machinability. Used for gears, pinions, bearings, bushings and many structural applications.
Glass with phenolic grades offer more mechanical strenght and moisture resistance. Often used as gaskets and seals.
Glass with melamine grades are specified for mechanical strenght and arc resistance. Used for circuit breaker parts, switchboard panels and arc barriers.
Glass with epoxy grades combine high mechanical strenght, good electrical properties, and excellent moisture resistance. Thses properties prevail at elevated temperatures. Used as structural members, slot insulation, wedges and panels. Flame retardant grades are available.
Glass with silicone grades provide excellent heat resistance and electrical properties. Used for heat shields, appliance insulation and high temperature electrical equipment.
