FEPA P grit,calcined,high temperature treated grain for producing high quality sanding belt,sanding paper,sand cloth,jumbo roll

Description:

AEHTP is a kind of blue color roasted, angular, sharp-edged Brown Fused Aluminum Oxides. The abrasive grains is calcined at high temperature to improve the instant adhesion to resin or glue bonds, and to exhibit a very increased toughness.

Applications:

AEHTP is used for production of all kinds of premium quality brown aluminum oxide coated abrasive products like abrasive cloth, paper and sanding belt.
