The acicular wollastonite powder of our company has substituted fibre asbestos, fibre talcum and fibre glass to be widely used in industry production, for its advantages of higher long-diameter d refractory materials and so on.
rate, good assistant ability, natural no social effects of pollution and lower cost.
Our products possess of a good sealed capability and large loaded capacity. Since its high melt point and small hot inflate coefficient, it’ll make the multi-material have good heat-resistance and shape and size’s stability; it is natural low-iron, less harmful impurity and no crystal water, so it will make finished products have excellent electricity capacity and physical and chemical capacity; it’s also an ideal substitution of asbestos, for its characteristics of white colour, special structure, no poison side-effect and high intensity and high friction-resistance.
