Product Description
3240is a laminated board prepared from alkali-free E-glasscloth impregnated with epoxy phenolic resin by pressing under high temperature and pressure. The 3240 cn be used in many electric fields and in humidity environment and in transformer oil.
Features:
1. High mechanical properties, its flexural strength(MR) are over 4000kgf/cm2
2. High dielectric properties
3. High adhesion strength
4. High thermal resistance.
5. High moisture resistance.Product Description
3240 epoxy fiber glass cloth laminated sheet /epoxy resin sheet is made by impregnating an alkali-free E glass cloth into epoxy resin and phenolic resin, then baking and hot pressing under high temperature and high pressure environment.
