Models: 3240 sheet: High mechanical and electrical applications, suitable for insulation structural parts of machinery and electric equipments under wet condition, available in transformer oil and humidity.
3240B sheet and 3240C sheet are similar to 3240, but with lower properties.
Application:
Epoxy glass cloth laminated sheets(insulation sheet,industry laminate sheet,Epoxy sheet) are made of alkali-free E-glass cloth impregnated with epoxy resins and phenolic resins by processing under heat and pressure. Epoxy glass 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.
