Phenolic resin cotton cloth tube is tube-like laminated products, which is made of special cotton cloth impregnated with phenolic resin, and then rolled, baked and cured under heat and hot pressing. It has excellent radial tensile strength, good mechanical strength and low water absorption. The insulation class is E class and the main color is coffee. It is widely used for mechanical, electronic applications. Surface has the vanished and non vanished treatment, the vanished surface will improve the property under the humidity conditions.
