Electrical Insulation Material Phenolic Wool Board Product Data

Grade: 3205. (Type: Cotton Based Laminates)

Description:

Phenolic Cotton Fabric Laminate, often referred to as "phenolic cotton" or "phenolic fabric laminate," is a type of composite material made by impregnating layers of cotton fabric with a phenolic resin and then curing the material under heat and pressure. This process creates a strong, durable, and versatile material with various applications.   

Comments: A high strength Class B rigid insulation with good electrical property and mechanical property. It is wear-resisting and applies to wear-resisting and insulating parts of mechanical, motor and electrical equipments, such as gear machining, mold machining.
