What makes ceramic abrasive technology superior? It comes down to durability and precision engineering.
Self-Sharpening Grain: Ceramic particles break down into sharp points, whereas Aluminum Oxide rounds over and loses its cut.
Cooler Sanding: The high efficiency of high performance abrasives reduces friction, preventing heat discoloration on delicate workpieces.
Film vs. Paper: Our ceramic series uses a PET film backing that won’t tear or clog, outlasting traditional paper products by a significant margin.
Material Versatility: Perfect for everything from tough metal deburring to fine automotive lacquer polishing.
Self-Sharpening Ceramic Grains: Unlike aluminum oxide, our ceramic grains micro-fracture under pressure, constantly exposing new sharp edges for a consistent cut throughout the disc's life.
75μm Micro-Flat PET Backing: We eliminate the “orange peel” effect caused by uneven paper fibers. Our ceramic abrasive ensures every grain sits at a uniform height.
Electrostatic Grain Orientation: We use high-voltage fields to stand grains upright, ensuring the sharpest points make contact with the workpiece first.
Proprietary Heat-Resistant PSA: Our Pressure Sensitive Adhesive is rated for high-friction temperatures (up to 80°C), ensuring Zero Glue Residue on your backup pads.
The primary advantage lies in the grain structure. Ceramic abrasive grains are micro-crystalline, meaning they “micro-fracture” during use to constantly expose new sharp edges. Unlike aluminum oxide, which dulls and rounds over, ceramic film maintains a high cut rate throughout its life. Additionally, the 75μm PET film backing provides a level of flatness and tear resistance that traditional paper products cannot match, making them true high performance abrasives.
Yes. Because the AF Series (AF37M, AF38M, AF39M) utilizes a high-strength polyester (PET) film backing rather than paper, it is 100% waterproof. It will not soften, curl, or lose its structural integrity when used with water or specialized sanding lubricants, ensuring consistent performance in automotive and marine environments.
election depends on your specific application:
AF37M: Best for ultra-fine finishing and clear coat repair (P600–P3000). It features a flexible film and a premium anti-clogging layer.
AF38M: Our versatile “all-rounder” for primer, e-coat, and wood sanding (P80–P1500).
AF39M: Engineered for heavy-duty metal deburring and composite sanding (P40–P1200) where maximum tear resistance is required.
Fuji Star's high performance abrasives are treated with a specialized zinc stearate top-coat. This “anti-loading” layer reduces friction and prevents dust from sticking to the abrasive surface. Combined with our electrostatic grain orientation, this ensures that dust is moved into the extraction holes efficiently, extending the life of the disc by up to 300%.
No. As leading self adhesive abrasive film manufacturers, Fuji Star uses a high-grade, heat-resistant Pressure Sensitive Adhesive (PSA). It is designed to withstand the high temperatures generated during industrial grinding (up to 80°C) without transferring glue residue to your backup pads, ensuring a clean and fast disc change every time.
