Redwood Plastics Redco™ PHENOLIC LE 221 Phenolic, Fine Weave Fabric
Categories: Polymer; Thermoset; Phenolic

Material Notes: Redco™ Phenolic is the strongest and toughest of materials in our product line. Redco™ Phenolic has an excellent compressive strength (up to 35,000 PSI) and incredible impact strength. Redco™ Phenolic is available in over 50 different grades with a variety of fillers including glass, cotton, melamine, silicone, and polyester. It is the cloth or glass reinforcement that gives the laminate its incredible toughness and/or superior dielectric strength. Redco™ Industrial Laminates are manufactured in hundreds of shapes, sizes, and grades. The wide range of physical properties offered by high pressure laminates allows for unlimited application considerations. Redco™ High Pressure Laminates have been used for such varied applications as insulating sleeves on high voltage equipment, pin bushings on heavy equipment, and high pressure guides on bandmills.

Typical Applications: Bushings, bearings, wearstrip, vibrating conveyor supports, insulating washers & spac¬ers, gears, switch board panels, doctor blades, oil seal rings, slip rings, sound insulators, guides, grommets, bobbins, thrust washers, wear plates, end posts, wire stranders, coils/ coil supports, end laminations, fuse cases, high voltage, televi¬sion, insulation, insulat¬ing structural members, primary and secondary, barrier insulation, relay insulation, slot cell insula¬tion, spool heads, standoff insulators, stator/generator insula¬tion, switchboard panels, switches, tap chang¬ers, terminal boards, top sticks, etc.
