Import Epoxy Glass Fabric Laminated Sheets (G10/Fr4/G11 — Buy in Bulk from Supplier in China

Epoxy glass fabric laminated sheets from Nova Insulation Co. are manufactured in compliance with IEC 60893-2-1 and DIN 40893 standards, available in NEMA grades G-10, FR-4, and G-11. Thickness ranges from 0.5 mm to 25 mm, with standard dimensions of 1000 mm x 2000 mm, and density between 1.70 and 1.95 g/cm³. These sheets exhibit dielectric strength exceeding 20 kV/mm and volume resistivity above 10¹² Ω·cm at 23°C, making them suitable for high-voltage insulation applications.

The base material consists of woven E-glass fabric impregnated with brominated epoxy resin, with FR-4 grade containing flame-retardant additives meeting UL94 V-0 requirements. G-11 offers higher thermal class (180°C) than FR-4 (130°C), while G-10 lacks flame retardancy but provides superior mechanical rigidity. Moisture absorption is typically below 0.20% after 24-hour immersion, and thermal expansion coefficients range from 12 to 18 ppm/°C along the plane. Surface finish is smooth and machinable, with tolerance ±0.1 mm on thickness for precision parts.

These laminates are primarily used in printed circuit boards, transformer spacers, switchgear insulators, and aerospace structural components. Buyers include PCB manufacturers, electrical equipment assemblers, and industrial automation suppliers. Packaging is in rigid cardboard boxes with moisture barrier film, with standard pallet quantities of 100 sheets. Trade terms offered include FOB Shenzhen and CIF, with lead times of 10 to 15 working days after order confirmation. MOQ is not specified and must be confirmed directly with the supplier.

Nova Insulation Co. is a supplier based in Shekou, Shenzhen, with verified export activity and harbor-level trust signals indicating consistent shipment history. The listing confirms no manufacturing facility details, no certifications held, and no direct production claims. The supplier acts as an exporter or distributor sourcing these laminates from upstream manufacturers in Guangdong province, with no public information on workforce size, revenue, or client list.

There is no indication of in-house R&D, testing labs, or ISO certification. Response rate and average response time are not recorded, suggesting limited buyer engagement or automated communication. The supplier's capability is limited to fulfilling export orders with standard packaging and logistics, without evidence of custom fabrication, grading validation, or technical support beyond basic shipment coordination.
