Treated White Fused AluminaTWA
Description:
TWA is White Fused Alumina produced by fusion of high purity alumina in an electric arc furnace and controlled solidification process.
Its low impurity contents and monocrystalline structure provide very high hardness and abrasion resistance.
Especially, TWA shows excellent compatibility with resins by specific chemical treatment.
TWA could be adapted to the laminated floor and decorative paper for the enhancement of wear resistance and high transparency.
