Import 3240 Epoxy Phenolic Glass Sheet For Battery — Buy in wholesale FOB from Supplier in Global Markets

The 3240 epoxy phenolic glass sheet for battery applications from Wuxi Chifeng Metal Products Co., Ltd is a rigid laminate produced by impregnating alkali-free E-glass woven fabric with a blended epoxy and phenolic resin system, followed by bake and hot-press curing. Supplied dimensions include 1020 mm by 1220 mm, 1020 mm by 2020 mm, and 1220 mm by 2440 mm, with thickness spanning 0.5 mm to 100 mm. The yellow-coloured sheet targets battery pack insulation, busbar isolation, and structural spacers where mechanical rigidity and electrical isolation must coexist in a compact envelope.

The resin formulation combines epoxy's adhesion and chemical resistance with phenolic thermal stability, yielding a laminate with typical flexural strength of 150-250 MPa and compressive strength of 200-300 MPa at ambient conditions. The alkali-free E-glass reinforcement minimises ionic contamination risk near battery terminals, a consideration for long-term electrochemical stability. Colour consistency, void content, and resin flow during cure all influence dielectric performance, so buyers should request batch test data rather than assuming catalog values. Standard density for this grade falls in the 1.75-1.95 g/cm3 range.

Battery manufacturers, energy storage system integrators, and electric vehicle pack assemblers represent the core demand for this format. The broad thickness range allows the same material family to serve as thin slot liners, thick terminal barriers, or machined structural brackets. Custom dimensions are offered, though tolerances and cut edge quality need specification. Trade specifics such as MOQ, price, lead time, and export packaging configuration are not provided in the source and must be confirmed directly with Wuxi Chifeng Metal Products Co., Ltd before finalising procurement.

Wuxi Chifeng Metal Products Co., Ltd is located at Saige Mansion on Huishan Main Road, Wuxi City, Jiangsu Province, 214000, China. The supplier carries a harbor trust tier with a response rate of 0.00% and zero recorded average response hours. The company name references metal products, but the listing covers epoxy glass laminate insulation sheet, suggesting either a diversified product range or trading operation without captive laminate manufacturing.

No factory size, annual turnover, employee count, or client references are available in the source data. The supplier does not list certifications such as ISO 9001, ISO 14001, or IATF 16949, nor does it cite battery-specific approvals like UL 1973 or IEC 62619. Buyers should request business licence scope verification, factory audit capability, and direct evidence of epoxy laminate production experience before relying on this source for critical battery insulation supply. The absence of response metrics indicates that proactive follow-up and alternative communication channels may be necessary.
