Import Fiberglass Backing Plate — Buy in Bulk from Supplier in China

The Fiberglass backing plate from Zhengzhou Purui Industial Trading Co., Ltd. is a structural component designed to support grinding wheels in industrial abrasive applications. It features a T27 flat profile with inner diameter options of 16mm or 23mm, held to a tolerance of 0.1mm to ensure precise mounting on spindle arbors. The plate is constructed with 4 to 14 layers of woven fiberglass resin laminate, providing rigidity under high rotational stress while resisting delamination during prolonged use.

Fiberglass backing plates in this category typically use E-glass or C-glass fibers bonded with phenolic or epoxy resins, offering thermal stability up to 120°C and resistance to moisture ingress. Layer count varies by application: 4-6 layers suit light-duty polishing, while 10-14 layers are standard for heavy grinding in metalworking. The inclusion of one or two steel washers is optional and aligns with ANSI B7.1 or ISO 8486-1 standards for wheel mounting systems, though the supplier does not confirm adherence to these standards.

This backing plate is primarily purchased by manufacturers of angle grinders, surface grinders, and CNC abrasive tools, particularly in automotive parts finishing and foundry operations. Buyers typically order in batches of 500 to 5,000 units, with packaging in corrugated cartons of 100 plates per box. Trade terms are flexible, but lead time and Incoterms must be confirmed directly with the supplier, as no specific values are disclosed in the listing.
