从China供应商批发进口3725 Phenolic Cotton Cloth Laminated Rod — FOB条款

The 3725 phenolic cotton cloth laminated rod from Ztelec Group is an industrial-grade insulating material made from white cotton cloth and phenolic resin. It meets the GB 5133-85 executive standard and carries a temperature classification of E, making it suitable for continuous operation at elevated temperatures up to 120°C. The material is engineered for high mechanical strength, excellent electrical insulation, and good machinability, allowing for precise fabrication into structural components.

This grade is a standard phenolic laminate used widely in electrical and mechanical industries. Typical compositions include layers of cotton cloth impregnated with phenolic resin, compressed under heat to form a dense, homogeneous rod. The standard density for this grade is around 1.3 to 1.4 g/cm³, with a tensile strength of 90 MPa typical for the category. Surface resistance generally exceeds 10¹² ohms, and dielectric strength is commonly above 15 MV/m, ensuring reliable performance in high-voltage applications.

Primary applications include insulation structural parts in electric apparatus, such as switchgear, transformers, and motor components, as well as wear-resistant mechanical parts like gears, pulleys, and bearings. Buyers sourcing this material typically specify diameters and lengths to match their machining requirements. The rod is supplied in standard brown or natural finish, with custom lengths available upon request. Confirm minimum order quantities and packaging options directly with Ztelec Group.
