Import Alkyd Varnished Glass Cloth — Buy in Bulk from Supplier in China

Alkyd varnished glass cloth is a woven glass fabric impregnated with alkyd resin varnish and heat-cured to form a flexible electrical insulation material. The base cloth is typically woven from E-glass or C-glass filaments, with the alkyd varnish providing bonding and environmental protection. The source description cites high dielectric strength, heat resistance, and resistance to oil, fungus, and humidity as key properties, though no specific temperature class, voltage rating, or thickness values are stated in the available data. Buyers should request these exact figures before specifying the material for a particular application.

The alkyd resin system used in this product is typically based on glycerol or pentaerythritol esterified with fatty acids and dibasic acids, cured to a hard but flexible film. Standard industry grades for alkyd varnished glass cloth range from 0.08 mm to 0.30 mm in thickness, with common widths of 900 mm, 1000 mm, or 1200 mm. The varnish content by weight typically falls between 25% and 40%, depending on the required electrical and mechanical balance. The glass cloth substrate provides tensile strength in excess of 1500 N per 25 mm width in the warp direction for standard weaves. Without supplier-confirmed figures, buyers should treat these as typical industry values and request a mill certificate or test report.

This material finds primary use in slot insulation, phase insulation, and coil wrapping for electric motors, generators, and transformers where Class B (130 degrees C) or Class F (155 degrees C) insulation is required. It also serves as a protective wrapping for cables and harnesses in automotive and aerospace applications where resistance to hydraulic fluids, lubricating oils, and moisture is essential. The source description mentions flexible minimum order quantities, but no MOQ, price, or lead time is specified. Buyers sourcing from Henan Yaan Electrical Insulation Material Plant Co., Ltd, located on Laodong Road in Xuchang, Henan, should confirm trade terms, Incoterms, and delivery schedules directly with the supplier.

Henan Yaan Electrical Insulation Material Plant Co., Ltd is located on Laodong Road, Xuchang, Henan Province, China, postal code 461000. The supplier is categorised as an imported-tier listing with a harbor trust tier. The response rate is shown as 0.00% with an average response time of zero hours, indicating either a new listing, limited platform activity, or incomplete engagement metrics. Buyers should not assume responsiveness based on these figures and should initiate direct contact to gauge communication reliability.

The source description positions the company as a manufacturer of electrical insulation materials, specifically highlighting alkyd varnished glass cloth for industrial applications. No information about factory size, year of establishment, annual output, number of employees, or specific quality certifications (such as ISO 9001, ISO 14001, or IECQ) is provided in the available data. The listing does not state any export experience, client references, or third-party verification of manufacturing capability. Buyers are advised to request a company profile, quality management system certificates, and product test reports before committing to volume orders.
