Huizhou Zheng Sheng Precision Work Science Technology Co., Ltd.
This laminating product is formed under high-heat and high pressure after electric industry fiberglass cloth dipped into the epoxy phenolic resin. It is of high mechanic,dielectric performance and great heat-resistant properties as insulation structural components for electromechanical/electrical equipment and it can be used under damp environmental conditions and transformer oil .
Technical requirement for surface
Technically,the surface of laminating board should be flat and smooth, no bubble, no wrinkle and no delamination or crackle as well.Other defects such as scrape, impress,dirty spot and uneven color can not be accepted.
But the tolerence of the surface verifies according to industries and concrete purposes.
Feature
·Long shelf life
·Impact resistant
·Thermal Insulation
·No VOC substances
·Low shrink during cure
·Great eletrical properties
·Excellent moisture resistance
·Excellent chemicai resistance
·Increased mechanical and fatigue strengh
