Our plastic backing discs for flap discs are made of premium synthetic plastics, a key component that ensures stable grinding performance. Flap disc backings are commonly classified into two types: fiberglass substrates and plastic substrates. Fiberglass substrates, manufactured with high-quality fiberglass composites, excel in air permeability, high ductility and strong abrasive bonding, keeping abrasives firmly attached without easy shedding. Additionally, some of these materials are recyclable, meeting the growing demand for environmental protection in industrial applications.

 

Plastic substrates stand out with exceptional high hardness derived from premium plastic materials, ideal for heavy-duty high-pressure grinding operations. This excellent hardness effectively absorbs impact and friction exerted on the flaps, greatly prolonging the service life of flap discs and reducing replacement costs for customers. With a sleek, smooth surface, plastic substrates boast reliable waterproof, dustproof and anti-aging properties, and they won’t absorb impurities—ensuring long-lasting performance and easy storage even in harsh working environments. To meet diverse needs, plastic backing discs offer a wide spectrum of color choices for better aesthetics, and can be tailor-made into various shapes to fit different grinding scenarios and customer requirements.
