3025, H3136 Phenol Aldehyde Cloth Laminated Board

Product Description

H3025-D Phenol aldehyde cloth board series
3025, H3136 phenol aldehyde cloth laminated board

1. Define and purpose
3025 is formed through drying and heat pressing after the cotton cloth dips into PF resins. H3136 is formed as laminated board through heat pressing after the blanc dips into PF resins. 3025 has high mechanical performance and is used as insulation structural components for machinery, electric engine and electric equipment, as well as used in transformer oil. H3136 has very high mechanical strength, suitable to be used as the components of mechanical products such as the bush of rubber cloth gears, guide wheel.

2. Technical requirement
2.1 Outside appearance
Laminated board surface should be flat and tidy. The bubbles, sand holes and inclusions are not allowed. A little of spots are allowed. The edge should be cut tidy. There is no delamination and crackle on end surface.
2.2 Main performance index
