3240 Epoxy Fiber Glass Sheet
Name: 3240 EpoxyFiber Glass Sheet
Color include: yellow
ShapesInclude:Sheets
1. Define and purpose
Thislaminated product is formed through heat pressing after electric industryalkali glass cloth dips into the epoxy phenolic resin. It has high mechanic anddielectric performance, and applicable as insulation structural components forelectromechanical/electrical equipment, as well as used under dampenvironmental conditions and transformer oil .
2. Technical requirement for surface
Thesurface of laminated board should be flat and smooth, no bubble, no wrinkle, nodelamination or crackle, and properly free from other defects such as scrape, impress,
dirty spot and unevencolor, but a little color patches is allowed.。
