Import 3240 Epoxy Resin Insulation Laminate Sheet — Buy in wholesale FOB from Supplier in China

3240 epoxy phenolic glass cloth laminated sheet is a rigid insulation material manufactured from alkali-free E-glass cloth impregnated with epoxy and phenolic resins, then cured under heat and pressure. The source material cites two model variants: 3240A, which delivers higher mechanical and electrical properties for use in wet conditions and transformer oil, and 3240B with reduced properties. Nominal sheet dimensions are 1020 by 2040 mm, with thicknesses spanning 0.5 mm to 100 mm. The supplier, Shenzhen Xiongyihua Plastic Insulation Ltd., operates from Longgang District in Shenzhen, Guangdong Province.

The glass cloth reinforcement provides dimensional stability and mechanical strength, while the epoxy-phenolic resin matrix delivers electrical insulation and moisture resistance. 3240A grade offers superior dielectric strength and flexural strength compared to 3240B, making it preferred for critical electrical insulation structural parts. Standard industry applications include transformer insulation, motor slot wedges, switchgear barriers, and control panel bases. The material can be machined, drilled, and punched to custom shapes without delamination when proper tools and speeds are used.

Buyers are typically electrical equipment manufacturers, transformer repair shops, and railway/automotive component suppliers seeking certified insulation materials. The product serves humidity-exposed environments and oil-immersed applications where tracking resistance and dielectric integrity matter.
