1.DEscriptION
Phenolic cotton cloth laminated tube/pipe 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.
2.FEATURES
#Good dielectric properties
#Excellent mechanical strength
-#Good for processing
3.APPLIATIONS
PFCC21 Phenolic cotton cloth tube has high radial tensile strength and can be used as a seal ring, bearing cage, and other wear parts.
