Green Plastic Fiber Backing Flap Disc Plastic Backing polishing and grinding Backing. The plastic backing discs for flap discs are crafted from high-grade synthetic plastics. Flap disc backings mainly fall into two categories: fiberglass substrates and plastic substrates. Made from fiberglass composites, fiberglass substrates deliver excellent air permeability, high ductility and strong abrasive adhesion, effectively preventing abrasive particles from falling off during operation. What's more, partial materials are recyclable, perfectly aligning with current eco-friendly procurement standards.

Thanks to the inherent properties of plastics, plastic substrates feature outstanding high hardness, making them well-suited for high-pressure grinding applications. This superior hardness also helps absorb impact and friction on the flaps, significantly extending the overall service life of flap discs. Boasting a smooth surface, plastic substrates offer excellent waterproof, dustproof and anti-aging performance, with no impurity absorption to ensure consistent performance over time. For enhanced aesthetics, plastic backing discs come in a diverse range of color options, and can be customized into various shapes to cater to customers' distinct application requirements.
