Pollution
resistance--After
high temperature calcinations of 12000C, the product has low water
absorption, and the pores of the tile surface are extreme small preventing
the stains from penetrating.
Anti-electrostatic—The
product has the anti-electrostatics function and is applicable to the wall
and floor decorations where anti-electrostatic is required.
Low radioactivity—The
base materials without radioactive radon, tested by national building
materials testing center, products conform to GB6566-200.! Category.
