Pure China Clay Powder is a hydrated aluminum silicate that is micronized with controlled particle size. Main attributes of our China Clay Powder are high brightness, better chemical resistance, prevents crack tendency, improves surface quality and high opacity. Further, the distinctive features in paint are as follows : Improves opacity Higher tinting strength Better scrub resistance Corrosion resistance High gloss Higher thixotropic nature Anti-cracking The China Clay Powder has applications in fields such as : HDPE : imparts higher tensile strength & stiffness to HDPE PVC : mainly used to increase specific resistance of cable compounds & provides anti-tackiness Mechanical rubber goods : improves properties like good process ability, low mill sticking & uniform cure rates Other plastics rubber : improves tensile, flexural modules & make a significant increase in impact strength Specification of China Clay Powder : SiO 2 45% to 48% Al 2 O 3 33% to 39% Fe 2 O 3 below 1. 5% TiO 2 below 0. 5% CaO below 1% MgO below 0. 5% LOI 12% to 14% Acid Insoluble 97. 5% ph 8. 1 B.
