Product Description
3021 Phenolic paper laminate sheet
phenolic paper is called phenolic laminated sheet.  a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with phenolic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.
Phenolic Paper Laminated Insulation Sheet is made of insulation paper impregnated by phenolic resin.
Heat-resistance: Eclass  120ºC
Material: phenolic paper and phenolic resin
Property: With high dielectric and mechanical property under normal condition.
Application: with good mechanical performance and electric performance for motors and electrical apparatus ,as well as transformer oil.
The specification:  Thickness(mm): 1-120mm
Size: 980X1980mm, 1020X2040mm
Package: pallet     Storage life---1 year
