Black Plastic Fiberglass Backing Pads High Hardness Waterproof For Sanding Flap Disc 150mm

Plastic backing discs for flap discs are manufactured from premium synthetic plastics to deliver enhanced durability and optimal performance. Flap disc backings are available in two primary types: fiberglass substrates and plastic substrates. Fiberglass substrates, constructed from high-grade fiberglass composites, offer excellent air permeability, high ductility, and strong abrasive adhesion that securely locks abrasives in place during operation. Some variants are recyclable, meeting the growing eco-friendly requirements of modern industrial applications.

Plastic substrates feature inherent high hardness, making them ideal for heavy-duty, high-pressure grinding applications. This structural hardness effectively absorbs impact and friction on flaps, reducing wear and significantly extending the overall service life of flap discs. The smooth, dense surface ensures superior waterproof, dustproof, and anti-aging performance with no impurity absorption, enabling stable operation even in demanding working environments. Additionally, plastic backing discs offer multiple color options for enhanced aesthetics and can be fully customized into various shapes to precisely meet customers' specific application requirements across diverse grinding scenarios.
