Green SiC powder 4000# for Polyester sanding film
Polyester sandpaper, also known as polyester sanding film. It is a special sandpaper with the base of deformable polyester film. Applications mostly for high precision, such as automotive paint polishing, precision mold crankshafts, semiconductors, aerospace, etc.
According to the different abrasives, there are alumina sanding film and silicon carbide sanding film. Sanding film made of green SiC 4000 # or finer powder is suitable for metallographic grinding, precision alloy parts, fiber optic grinding, optical glass, electronic ceramics, and other aspects. The polyester matrix has the characteristics of stretchability and elasticity. The fine abrasive powder of green SiC 4000 helps the film abrasives get fine toughness. It has the characteristics of fine and uniform particles and a strong grinding force of impurity sand. The combination of the two reflects good performance.
