White aluminum oxide P180 P220 for coated abrasives
Production of White aluminum oxide P180 P220 for coated abrasives
White aluminum oxide P180 P220 for coated abrasives is an elector-fused corundum with a special grit shape and density. The process of crushing and sieving process are different from F grit series. White aluminum oxide P grit has been processed on a roller machine production line, with a lower bulk density and more concentrated particle distribution compared WFA F-Grit. It has high self-sharpening and toughness, low magnetic content, and high cleanliness. P standard grits are mainly used for the production of coated abrasives and abrasive products that need to adhere the abrasives to the surface of the substrate. Its particle shape is mostly long and uniform in size, which facilitates the uniform adhesion of abrasives to the substrate and prolongs the service life of the abrasives.
Characteristics of White aluminum oxide P180 P220 for coated abrasives
- Uniform particle size and narrow particle size distribution range.
- The raw material is an A-grade fixed furnace white fused alumina with strong toughness.
- Acid alkali washing and water washing, resulting in high cleanliness.
- The particle shape of WFA P grit is multi-angular, strip-shaped, and has a higher sharpness.

Features of White fused alumina P-Grit:
White fused alumina P-grit abrasive material from HAIXU Abrasives is made from fixing furnace fused alumina blocks which are smelting by high purity aluminum oxide powder. White fused alumina P-Grit are produced by special milling equipment and technology. The WA P-Grit is of more consistent particle size. That will make grains easier to stick on the base of coated abrasives. It can be stuck firmly by bonder glue to a cloth or paper base. The advantages include high toughness, good particle distribution, shape grain size.
Main Application of white fused alumina P-Grit
- Grinding sandpaper and cloth
- Nylon polishing wheel
- Nail strips and tools
- Non-woven abrasives discs

Q: What is the content of Na2O in your WFA grains?
A: We have normal Sodium WFA grain and low Sodium WFA grain. Normal WFA grain Na2O content is max. 3% which is lower than most competitors. Low sodium WFA grain Na2O content is max.0.1%.
Q: Do you have a MOQ of WFA grain?
A: Generally no limit of MOQ. Even 25kgs(1 bag)is ok for us. But the logistic cost will be higher than normal.
Q: Can you provide free samples?
A: Yes, 1kgs free sample is available, customer has to bear the express cost.
Q: What is the lead time of FCL WFA grain?
A: Generally 7-10 days after receiving the deposit.
