1. Product introduction

Wollastonite belongs to triclinic, crystal usually extends along Y-axis and becomes board shape, bacilliform or acicular. Pure wollastonite appears to be white, ivory-white light gray, light green or pink colour. Its appearance has vitreous luster.

Our company can manufacture many kinds of fine wollastonite powder, it is all manufactured by high quality raw materials. It has many good characteristics, such as granularity equality, homogeneous, high purity, endless catenulate, acicular crystallize, high whiteness, low ferrous, minimum S, P, low oil-absorption and etc.

Q:Silica powder and calcite powder have big difference
Wollastonite is a chain metasilicate, and is a kind of fiber like needle. Because of its special crystal morphology, crystalline structure determines its properties. Wollastonite has good insulation, high whiteness, good dielectric properties and high heat resistance and weather resistance.
Q:Does plastic modification add wollastonite to improve tearing properties?
However, the tearing properties of materials are generally applicable to films. If this is the case, I estimate that the tear properties of the film will not be improved by adding mineral fillers
Q:The difference between silica powder and wollastonite powder
Due to its special crystal morphology crystalline structure determines the properties of wollastonite, has good insulation, and has high whiteness, good dielectric properties and high heat resistance and weatherability. Because wollastonite is widely used in ceramics, chemical industry, metallurgy, papermaking, plastic, paint and other fields.
Q:What are the surface modification methods and processes of wollastonite?
Wollastonite is a calcium metasilicate mineral, often white and greyish white, with a glassy luster to a pearly luster. Because of its non-toxic, chemical corrosion resistance, thermal stability and dimensional stability, good mechanical and electrical properties, as well as strengthening and other advantages, it is widely used as reinforced fillers for polymer matrix composites.
Q:Chemical TSP and wollastonite filled nylon do contrast to the good toughness
Chemical TSP and wollastonite filled nylon do contrast to the good toughness
Q:Main characteristics of Wollastonite
Wollastonite is a chain metasilicate, and is a kind of fiber like needle. Because of its special crystal morphology, crystalline structure determines its properties. Wollastonite has good insulation, high whiteness, good dielectric properties and high heat resistance and weather resistance. Wollastonite is widely used in the fields of ceramics, chemical industry, metallurgy, paper making, plastics, coating and so on.
Q:World resources of Wollastonite
At present, the application in the high-end market is very optimistic. At present, domestic enterprises have begun to carry out deep processing of wollastonite, synchronous application research, I believe that in the next 2-3 years, there will be a domestic enterprises among the forefront of the world wollastonite industry.
Q:The difference between wollastonite and quartzite
Quartz sand is quartz quartz stone crushing processed. Rock (quartz), also known as silica, is a hard, abrasion resistant and chemically stable silicate mineral. In nature, quartz sandstone, quartzite and quartz quartz exist. Quartz sandstone is a consolidated clastic rock with a quartz content of more than 95%.
Q:What is the difference between wollastonite powder and talc powder?
The medicine - food grade (YS): medicine tablet, medicine powder (such as Paracetamol Caffeine and Aspirinpowder), sugar powder and traditional Chinese medicine prescriptions, food additives, separant.Talc (3) coating grade (TL): used for white pigment and various water base, oil base, resin, industrial coating, primer, protective paint, etc..
Q:What are the specific applications of wollastonite in coatings?
The use of needle like wollastonite 6, insulation, insulation materials, glass products and polymer composite materials, etc., can improve the product strength, hardness, and heat resistance, bending resistance, corrosion resistance.
