Phenolic Cotton Cloth Laminated Sheet

1 .Definition and purpose

This product is formed into laminated board through drying and heat pressing after cotton cloth dips into PF resins. It is suitable as the structural components with a certain mechanical performance and electric performance for machinery, electric engine and electric equipment.

2 .Technical requirement

2.1 Outside appearance:The surface of laminated board should be flat and smooth, no bubble, no wrinkle or crackle, and properly free from other defects such as scrape, impress, dirt spot and uneven color, but a little color sports is allowed.2.2 Main performance index
