Import 3240 Epoxy Phenolic Glass Cloth Laminated Sheet — Buy in wholesale FOB from Supplier in China

The 3240 epoxy phenolic glass cloth laminated sheet from Shenzhen Xiongyihua Plastic Insulation Ltd. is a medium-temperature engineering laminate built from epoxy resin and alkali-free E-glass fiber cloth. The 3240 grade designates a specific Chinese standard classification for epoxy glass cloth laminates, with a typical glass transition temperature (Tg) of 130 degrees C to 155 degrees C and a dielectric strength standard of 10-20 kV/mm. The sheet format suits machining into structural insulation components for electrical and mechanical assemblies.

Material construction follows the classic wet lay-up process: multiple plies of woven glass fabric are impregnated with epoxy-phenolic resin, stacked, and cured under heat and pressure. The phenolic modifier raises thermal endurance compared with straight epoxy systems, while the glass cloth reinforcement provides dimensional stability and mechanical strength in the 150-200 MPa flexural range, typical for this grade. Standard colour is yellow. The resin system contains no halogenated flame retardants in the base formulation, though buyers should confirm FR ratings if required for their application.

Primary buyers include motor repair shops, transformer manufacturers, and producers of switchgear, terminal blocks, and jigs. The material machines cleanly with carbide tooling and can be drilled, routed, and punched to tight tolerances. Typical supplied thicknesses range from 0.5 mm to 50 mm, with sheet sizes of 1020 mm by 2040 mm as standard, though cut pieces and custom dimensions are common. Trade terms, MOQ, and lead time should be confirmed directly with the supplier, as these are not stated in the listing.

Shenzhen Xiongyihua Plastic Insulation Ltd. operates from No.64 Jixiang Road in the Longteng Industrial Zone, Longcheng Street, Longgang District, Shenzhen, Guangdong Province, 518172, China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00% and zero recorded average response hours. This profile indicates limited active engagement signals, and buyers should factor this into their communication planning.

The company specialises in plastic insulation materials, with the 3240 epoxy phenolic glass cloth laminated sheet as a core stocked item. No verified certifications, factory audit reports, or production capacity figures are present in the source data. Buyers are advised to request ISO 9001 certification status, material test reports (MTRs), and batch-level dielectric test data before committing to an order. The listing describes the product in functional terms suitable for mechanical and electrical insulation parts, but does not claim specific industry approvals such as UL, RoHS, or REACH compliance.
