Phenolic Cotton Cloth Laminated Sheets
Electrotechnical sheet textolite or Phenolic Cotton Cloth Laminated Sheets is a laminated material made by hot pressing of cotton cloths impregnated with a thermosetting phenolformaldehydebased binder
Due to the use of cotton cloths the phenolic cotton cloth mixture has high compression strength and increased resilience favorably lends itself to machining by drilling cutting and forging That is why the phenolic epoxy resin cotton cloth laminated sheets are widely used to make parts loaded with reversed electrical and mechanical stresses or working under friction bushings cams etc
The textolite or phenolic cotton cloth sheets are used as insulating material for work in transformer oil and in the air at a normal relative humidity of the environment and at 50 Hz of frequency
Longterm allowable working temperature 65C to 105
Phenolic cotton cloth sheets benefits
very good mechanic and thermal properties
lasting operating temperature to 120C
approved for oil and air
low friction coefficient
high creep resistance
vibration absorption properties
easy mechanical processing
electroinsulation properties
Types of phenolic epoxy cotton cloth textolite sheets
Phenolic cotton cloth sheets type A has improved electrical properties and is mostly used as insulating material
Phenolic cotton cloth sheets type B same as type A but it has improved mechanical properties and is mostly used as a construction material
