3025 phenolic cotton cloth laminated sheet is a thermoset composite material manufactured from layers of woven cotton fabric impregnated with phenolic resin, pressed and cured under heat and pressure. Standard sheet dimensions are 1030 mm by 2030 mm or 1220 mm by 2440 mm, with thicknesses ranging from 0.5 mm to 80 mm. The material exhibits a vertical bending strength greater than 100 MPa, tensile strength exceeding 80 MPa, and notched impact strength above 8.8 kJ per square metre. Its characteristic brown colour derives from the phenolic resin and natural cotton fibre content.
The phenolic resin system used in 3025 grade is typically a resole-type phenol-formaldehyde condensation product, cured with an alkaline catalyst to achieve cross-linked thermoset properties. Cotton weave style (plain or twill), thread count, and fabric weight per square metre influence mechanical properties and machinability. Typical density for this grade is 1.30-1.40 g per cubic centimetre, with water absorption of 1.5-3.0 percent by mass after 24 hours immersion depending on thickness and resin content. The material maintains structural integrity up to continuous operating temperatures of 120-130 degrees C, with short-term capability to 150 degrees C. Electrical strength perpendicular to laminations is typically 10-15 kV per mm for thicknesses above 1 mm.
专家们指出,3025板材广泛应用于高压电气绝缘、断路器隔板、变压器端子板、焊接夹具、齿轮毛坯、以及需要兼顾机械强度和绝缘性能的机械加工部件。纺织机械、矿山设备、和通用工业机械中的耐磨垫片和轴承也采用此材料。买家应向无锡赤凤金属制品有限公司确认具体树脂配方是否符合UL或IEC绝缘系统要求,以及板材是否经过预干燥处理以减少后续加工中的变形。

Wuxi Chifeng Metal Products Co., Ltd is located at Saige Mansion on Huishan Main Road, Wuxi City, Jiangsu Province, postal code 214000. The company holds a harbor trust tier classification with a response rate of 0.00 percent and no recorded average response hours, indicating limited platform engagement data. No information on year of establishment, factory floor area, number of employees, revenue, or export markets is provided in the source profile.
The supplier lists 3025 phenolic cotton cloth laminated sheets in its product range alongside metal products, suggesting diversification into industrial composite materials. Buyers should directly verify whether the company manufactures laminates in-house or sources from a dedicated laminate producer, what quality control procedures are applied, and whether the product range extends to other NE grades (such as 3021 paper-based or 3240 epoxy glass). The Wuxi region has established supply chains for electrical insulation materials, which provides relevant industrial context.

Before ordering from Wuxi Chifeng Metal Products Co., Ltd, verify the exact sheet sizes and thicknesses held in stock versus made-to-order, as 80 mm thickness may require extended lead times. Request a material data sheet specifying resin type, cotton weave, and all mechanical and electrical properties quoted. Confirm whether the supplier provides test certificates from batch testing or only type test reports. For electrical insulation applications, verify whether the material has been tested to IEC 60893-3-4 or NEMA LI 1, and whether the supplier can provide third-party test reports from accredited laboratories. Ask for sample material to evaluate machinability and surface quality before committing to volume purchase.
Shipping from Wuxi City typically routes through Shanghai Port. Confirm Incoterms, whether the supplier handles export customs clearance, and what export packaging is used to protect sheets from moisture and mechanical damage during transit. Standard packing should include waterproof kraft paper interleaving and plywood crating for thicknesses above 3 mm. Lead time for standard sizes and thicknesses is typically 2-4 weeks for Chinese laminate suppliers, but confirm specifically with Wuxi Chifeng. Payment terms should be negotiated based on order value and verification of supplier reliability; consider documentary credit for initial orders exceeding 10,000 USD. Clarify responsibility for freight damage and insurance coverage during transit.
On receipt, inspect sheets for delamination, resin starved areas, foreign inclusions, and dimensional conformance to order. Check thickness with a micrometre at multiple points across the sheet, as thickness tolerance for phenolic laminates is typically plus/minus 0.2 mm up to 3 mm, plus/minus 0.3 mm for 3-6 mm, and plus/minus 5 percent above 6 mm. Store flat in dry conditions below 65 percent RH and below 25 degrees C to prevent moisture uptake and warp. Before machining, condition sheets to workshop temperature for 24 hours. Retain mill test certificates and batch numbers for traceability. For critical electrical applications, consider engaging SGS, Bureau Veritas, or equivalent to witness pre-shipment inspection and verify compliance with specified standards.
