Each entry falls within the broader categories of plastic sheets and laminates, electric insulators, and packaging items, matching the supplier’s top‑category classifications. The product list reflects a focus on dielectric and mechanical performance for industrial and electrical applications. No additional product families are mentioned beyond these nine items.

Product Range and Specialties of Xuchang Weidu District Yaan Insulating Material Plant

The supplier’s catalogue features three variants of polyester film (standard, 6520 and 6630), which are typically supplied as PET sheets with thicknesses ranging from 0.05 mm to 0.5 mm and optical clarity suitable for packaging and electrical insulation. Heat‑treated fiberglass sleeving and the 2715 fiberglass item are generally produced in diameters from 2 mm to 20 mm and rated for continuous operating temperatures up to 250 °C, conforming to ASTM D2583 and IEC 60216 fire‑resistance classes. Oil‑varnished silk products (2210 and 2310) are woven polyester fabrics coated with oil‑resistant varnish, often meeting IEC 60216 grade B for thermal endurance and providing dielectric strength above 30 kV/mm. The 6640 NMN flexible laminates are multi‑layer polymer composites used for packaging and insulation, commonly delivering tensile strength of 30‑40 MPa and moisture barrier performance under 0.5 % water vapor transmission rate. Industry practice for these categories includes ISO 9001 quality management and, where applicable, UL‑94 flame‑rating for polymer films.

Trade and Export Information - Xuchang Weidu District Yaan Insulating Material Plant

China is a major exporter of plastic films, fiberglass insulation and laminated composites, with shipments typically directed to Southeast Asia, Europe and North America. Polyester films fall under HS Chapter 39 (e.g., 3919 90 for other polymer films), fiberglass products under HS 7015 90, and flexible laminates also under HS 3919. Buyers often require compliance with REACH and RoHS for polymer‑based items, while electrical insulators are frequently inspected for IEC 60216 thermal class and UL‑94 flammability ratings. Standard export logistics use 20‑ft or 40‑ft containers with shrink‑wrap or wooden palletized packaging, and Incoterms such as FOB Shanghai or CIF destination port are common. Chinese manufacturers of these goods regularly hold ISO 9001 certification, but buyers should verify any additional certifications specific to their market.

Sourcing from Xuchang Weidu District Yaan Insulating Material Plant - Buyer Guidance

When sourcing polyester film, request a material data sheet that lists thickness, tensile strength, elongation at break, dielectric strength and any fire‑rating (UL‑94 or IEC 60335). For fiberglass sleeving and the 2715 fiberglass, ask for test reports covering temperature rating, tensile modulus, and oil‑resistance performance, as well as an IEC 60216 certification copy. Oil‑varnished silk should be accompanied by oil‑penetration test results, dielectric strength values, and a fire‑class rating. Verify that the supplier can provide ISO 9001 certificates and, where required by the importing country, REACH compliance statements before confirming an order. Requesting a physical sample of each product type is standard practice to assess dimensional tolerances and surface finish.

What thickness ranges are available for the polyester films listed by the supplier?

The polyester films are offered in typical industrial thicknesses from 0.05 mm up to 0.5 mm, with each grade (standard, 6520, 6630) covering the full range depending on customer specification.

Are the heat‑treated fiberglass sleeving products suitable for high‑temperature environments?

Yes, the sleeving is heat‑treated to meet IEC 60216 grade B, allowing continuous operation at temperatures up to 250 °C and providing dielectric strength above 30 kV/mm.

What fire‑rating standards apply to the oil‑varnished silk fabrics (2210 and 2310)?

Both silk fabrics are coated to meet IEC 60216 thermal class requirements and are commonly tested for UL‑94 V‑0 or V‑1 flammability ratings, depending on the varnish formulation.

Which HS code chapters are most relevant for the supplier’s product categories?

Polyester films and flexible laminates fall under HS Chapter 39 (plastic films), while fiberglass sleeving and related glass‑fiber products are classified under HS Chapter 70 (glass fibre articles).

What documentation should a buyer request before purchasing the flexible NMN laminates?

Buyers should request a material safety data sheet (MSDS), a test report showing tensile strength (30‑40 MPa) and moisture barrier performance, and any applicable ISO 9001 or REACH compliance certificates.

What are typical minimum order quantities and lead times for these insulating materials?

Standard practice for polymer films and fiberglass products is a minimum order of one 20‑ft container (approximately 20‑25 metric tons) with lead times of 30‑45 days from order confirmation, subject to production scheduling.

How are the products packaged for international shipment?

Items are usually shrink‑wrapped on pallets or placed in bulk rolls, loaded into 20‑ft or 40‑ft containers with moisture‑controlled liners for the laminates, and secured with wooden dunnage for the insulated fabrics.

Which certifications are commonly required by importers of these materials?

Importers typically require ISO 9001 quality management certification, IEC 60216 thermal‑class certification for insulation, UL‑94 flammability rating for polymer films, and REACH compliance for chemical safety.
