Noticeable Acicular Mesh 2000 Calcium Metasilicate White

Grade:HGWD-2000

Product:High Quality Wollastonite Powder(Calcium metasilicate)


Construction: Wollastonite has found application as a substitute for asbestos in fire-resistant building products used in the construction industry. As a functional additive, wollastonite improves flexural and impact strengths. Its low thermal conductivity and high aspect ratio structure also makes wollastonite an attractive addition for applications requiring fire resistance. Wollastonite finds application in interior and exterior construction boards, roof tiles, shaped insulation products, sheets, panels and sidings.

Decriptions

Wollastonite is an inorganic needle-like mineral, and wollastonite products have very noticeable acicular and long fiber structures .It is characterized by non-toxicity, chemical corrosion resistance, good thermal stability and dimensional stability, glass and pearl luster, low water absorption and oil absorption value, excellent mechanical and electrical properties,even reinforcing effect. Wollastonite products with long fibers and easy separation, low iron content and high whiteness.

Wollatonite is Widely used in plastics, rubber, asbestos substitutes, paint coatings and other fields, it can increase the hardness, flexural strength, impact resistance of products, improve the electrical properties of materials, improve thermal stability and dimensional stability, and is the most promising application field. It is also used in the ceramics and metallurgical industries. The SiO2 and CaO components in wollastonite provide low expansion rate and good thermal shock resistance.



Application

Wollastonite is used for many different industrial purposes, including the production of:

Engineering technical plastics

Fluoro elastomer e.g. for oil sealing

heat-resistant refractory ceramics

metallurgy

wood composites

adhesives

filler in paint, paper and other products

friction products such as brake pads
