Micarta Linen Phenolic Rod
Micarta Linen Phenolic is a fine weave cotton fabric base phenolic laminate which provides a finer surface texture and better machinability than Grade CE. Grade LE is low in moisture pick-up and dissipation factor, and is excellent in all electrical properties.
It can be machined easily and cleanly to very close tolerances, and is recommended for use where there is need for good mechanical properties combined with excellent electrical characteristics.
Applications for Grade LE include intricate machined parts, radio components, fine gears and pinions, spacers, bushings and rollers.
As a class, phenolic compounds are characterized by low cost, superior heat resistance, high heat deflection temperatures, good electrical properties, flame resistance, excellent moldability and dimensional stability, and good water and chemical resistance.
They are of interest to the building and transportation industries due to their fire retardancy, low smoke generation and low smoke toxicity. Special purpose phenolics are formulated to meet specific requirements such as maximum dimensional stability at high temperature (in automotive transmission valves), cracking resistance (pump housings), stability in steam environments (steam irons, coffee makers), electrical resistance (high voltage switch gears) or good machining qualities (fine tooth gears).
Natural color Micarta canvas phenolic rod is typically light tan to brown. These grades are composed of a continuous cotton wovencloth impregnated with a phenolic resin binder.
Phenolics are the oldest, best-known general purpose thermoset resins. They are among the lowest cost and easiest to process. Phenolics are quite adequate for a fair percentage of electrical applications.
