Product Description

Materials and application:

This series of products are made of cotton cloth impregnated phenolic resin, then be dried and cured in mould under pressure with heat and machined to form a single rod.The products have good mechanical and dielectric properties ,and excellent machinability. The products are suitable for long lasting gears, pinion, bearing, bushing and many structural applications with the advantages of quieter and more economical than metal parts . 

 

Features:

- High mechanical properties,

-Good dielectric properties

-Thermal class E
