The 3725 phenolic cotton fiber laminated bar is a thermosetting composite made from phenolic resin and woven cotton cloth, designed for high-voltage electrical insulation and wear-resistant mechanical components. This grade offers strong dielectric properties, with a standard diameter range of 20 to 200 mm and a default length of 1000 mm, supplied in a brown finish to meet industrial identification norms. Its layered cotton fabric reinforcement provides high mechanical strength and impact resistance, making it suitable for heavy-duty applications.
The material composition combines phenolic resin as the binder with multiple plies of cotton cloth, resulting in a dense, homogeneous structure with excellent machinability. Typical industry standards for this class of laminated bar include a tensile strength of 80 to 120 MPa, a flexural strength of 120 to 160 MPa, and a dielectric strength of 5 to 8 kV/mm, though exact values depend on the specific formulation and curing process. It is also resistant to oils, solvents, and moderate temperatures, with a standard operating range up to 120°C.
Common applications include insulating spacers in electrical equipment, bushings, gears, and wear pads in machinery where dimensional stability and electrical isolation are critical. Buyers typically source this material in bulk for industrial manufacturing, with common trade terms including FOB or CFR from Chinese ports. The product is often used in power distribution, motor manufacturing, and machinery assembly, where reliability under electrical and mechanical stress is paramount.

Before ordering, verify the exact diameter and length tolerances with the supplier, as these can vary based on production batches. Request a material test report to confirm mechanical properties like tensile and flexural strength, as these are critical for load-bearing applications. Ensure the dielectric strength meets your equipment’s voltage requirements, especially for high-power electrical systems.
Confirm logistics details such as the nearest port of shipment (likely Shanghai or Ningbo for Wuxi-based suppliers) and whether the supplier offers FOB or CFR Incoterms. Lead times for custom sizes or large volumes may extend beyond standard stock, so clarify production schedules upfront. Payment terms should be agreed in writing, with common options including T/T or L/C for bulk orders.
For quality control, insist on third-party inspection for dimensions, surface finish, and dielectric properties before shipment. Check that the material’s moisture absorption rate is within the typical < 1.5% range to avoid performance issues in humid conditions. Documentation such as a certificate of conformance and test reports for mechanical and electrical properties should accompany the delivery.
