FINE WEAVE COTTON CLOTH PHENOLIC are made of cotton cloth impregnated phenolic resin by processing under heat and pressure.
 

C High mechanical applications, low electrical applications, primarily intended for mechanical field. Impact resistance, wear-resisting, sound-absorbing, low friction. Very suitable for as high load and wear resistance of components, operation in harsh high abrasion and high dust environment, bear the weathering and the sea.

CE: Suitable for mechanical and electrical applications, good electrical properties.

L High mechanical applications, low electrical application, good processing, especially suitable for has high mechanical stress and wear small parts, compared with C, L can produce more elaborate tolerance and the small surface roughness of parts.

LE: High mechanical applications, better than CE in electrical applications, suitable for small parts.

 

Nominal dimension : 1020×2040mm；1220×2440mm

Thickness: 0.5 ～ 100mm
