PRODUCT INTRODUCTION

 

Production Description


Bakelite sheet, also known as formica board, phenolic laminated paperboard, is one of laminated boards made by using bleached woody paper and lint paper as reinforcement materials and epoxy resin as resin adhesive. It possesses great dielectric property and machinability at room temperature with specific gravity of 1.45, excellent dielectric property and mechanical strength, and good anti-static and electrical insulation performance. The insulation class is E class and the main color is orange and black.

Application


Bakelite sheet is suitable for insulating structural spares in motors and electrical equipments with high mechanical performance requirements and can be used in transformer oil. Because of its excellent mechanical strength, it is also suitable for PCB drilling pad, table grinding base plate, distribution boxes, jig boards, mold plywood, high and low voltage wiring closet, packaging machine, forming machine, drilling machine, etc.
