Powdered Black carborundum P1500
Description:
Black Silicon carbide P-Grit Abrasive material is produced by a special milling process after melting quartz(the main chemical is SiO2) and petroleum coke(the main chemical is carbon). The Black silicon carbide P-Git has a sharper granule than F-Grit. That shape make grains more easily to glue sand onto coated abrasive base such as cloth and paper and stick tight on those bases.
Properties:
High hardness, retaining hardness and high wear resistance.
Excellent thermal shock resistance with high thermal conductivity and low linear thermal expansion.
Good particle distribution.
Good ability to withstand the strongest alkalis and acids.
Applications:
Lapping, polishing
Sanding paper, sanding wheel
Fiber disc, nylon polishing wheel
Non-woven polishing wheel
Sanding block, sanding sheet, sanding sponge,etc.
Knife Grinder, whetstone, oilstone, grinding stone, honing, sharpening sticks, etc.
Wear resistance layer on bakes, etc.
