Phenolic cotton cloth laminated sheets Your location:home > Products

  Phenolic cotton cloth laminated sheets(insulation sheet,industry laminate sheet,phenolic cloth sheet) are made of cotton cloth impregnated phenolic resin by processing under heat and pressure. Phenolic cloth sheet Can be processed into all kinds of insulation parts, The products are widely used transformers, electric motors, cabinets, control boxes, electric switches, household appliances, railway, automobile, computer and medical appliance,etc.

  Grade C sheets is intended for mechanical applications requiring high impact strength.Applications include gears and bearings,it has lower mechanical strength than materials with glass substrates,but has superior impact resistance when compared to paper based products,this material is not as suitable for fine machining as grade L.
  Grade CE sheets is intended for use in electrical applications requiring good moisture resistance and good mechanical strength,it has lower mechanical strength than materials with glass substrates,but has superior impact resistance when compared to paper based products,this material is not as suitable for fine machining as LE,CE possesses fairly good dielectric properties and medium dielectric loss.
  Grade L sheets is intended for machining and mechanical applications requiring a fine edge detail and appearance is required,it possesses a high density,good moisture resistance,and mechanical strength,it has lower mechanical strength than materials with glass substrates,but has superior impact resistance when compared to paper based products.
  Grade LE sheets is intended for electrical applications requiring good moisture resistance,it has lower mechanical strength than materials with glass substrates,but has superior impact resistance when compared to paper based products,it is suitable for fine machining,LE possesses fairly good dielectric properties and medium dielectric loss.
