Abrasives
We produce Silicon Carbide Abrasives as FEPA Standard, include bonded abrasives(F-Grit) / coated abrasives (P-Grit)/and we also can produce JIS series

P-Grit

P type Black SiC: P type products of silicon carbide are different to F type. It needs more strict procedure to produce and has more accurate grits distribution. Normally, it is commonly used in sandpaper industry.
Sizes Available: Grit sizes range from coarse grades down to a 2500 mesh size.

You can get more information of P240-P2500 from us via Email.
Custom Gradation: We offer custom gradation at no additional charge. Simply indicate the average micron you require when ordering, and we will custom screen material for you.
Particles mean size for available grits.
Grading: FEPA Standard
The mean diameters of macrogrits shown in the table are estimated and for information only, the FEPA "P" standard defines them as a range and not a single value.

The particle size distribution of macrogrits is determined by sieving, while the microgrits have been measured by sedimentation (photosedimentometer).
