Product Introduction
Production Description
3021 Phenolic Paper Sheet — natural color is typically orange or black. known as Phenolic paper laminated owns the character of good mechanical strength, anti-static, intermediate electrical insulation. It`s made by insulating paper impregnated with phenolic resin, after baking hot pressing. This product is suitable for high performance requirements of electrical machinery, electrical equipment as insulating structural parts, and in the transformer oil.
3021 Phenolic Paper Sheet provides good electrical properties and is used in switchgear and transformers as switchboards, panel boards, and insulating washers and bushings.
It has lot of advantages:
-
easy to machine
-
the lowest cost of phenolics
-
phenolic paper laminate has good wear resistance
-
low moisture absorption
-
good mechanical strength
-
phenolic paper laminate is strong and stiff
-
high impact and compressive strength
Strengths
1. Excellent dielectric properties
2. Great machinability and easy to process
3. Superior resistance to acid, chemical solvents and insulating oil
