The 3240 epoxy sheet is a thermosetting insulation material combining fiberglass reinforcement with epoxy resin, engineered for electrical switchgear, transformers, and circuit breaker applications. It delivers dielectric strength exceeding 20 kV/mm at 130 degrees Celsius, with mechanical toughness to resist deformation under load, as stated in the supplier’s technical notes. Standard thicknesses range from 0.5 mm to 50 mm, with customizable dimensions available to fit specific project requirements.
Material composition is fiberglass cloth impregnated with epoxy resin, cured to form a rigid laminate that meets IEC 60893 standards for electrical insulation. Typical industry specifications for such laminates include a density of 1.7 to 1.9 g/cm³, a flexural strength of 300 MPa minimum, and a water absorption rate below 0.5% after 24 hours immersion. The sheets are supplied in flat panels, with surface finishes that minimise moisture uptake and maintain dielectric stability in humid environments.
Primary buyers include manufacturers of electrical equipment, transformer assemblers, and switchgear producers in industrial and infrastructure sectors. The material is suited for use as barrier insulation, supporting structures, and arc-resistant components in medium and high-voltage systems. Confirm MOQ, packaging type, and lead time with Shenyang Youda Insulation Materials Co., Ltd., as these are not specified in the listing and may vary based on order size and destination port.

Before ordering, verify the dielectric strength and thermal class ratings to ensure compatibility with your electrical system’s voltage and temperature requirements. Request test certificates or third-party inspection reports to confirm compliance with IEC 60893 and other relevant standards. For applications with strict dimensional tolerances, provide detailed drawings to the supplier for approval.
Logistics details such as packaging type, palletisation, and container loading must be clarified with Shenyang Youda Insulation Materials Co., Ltd. Lead time can vary based on order volume, so confirm production and delivery schedules upfront. Incoterms like FOB Shenyang or CIF to your port should be negotiated to align with your import process and cost structure.
Quality checks should include visual inspection for surface defects, dimensional verification using calipers or micrometers, and dielectric testing if facilities are available. Request material test reports for each batch to validate mechanical and electrical properties. For critical applications, consider third-party inspection at the supplier’s facility or upon arrival to ensure the material meets your specifications.
