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.
• engineering technical plastics (PA, PU etc.) for the automotive
industry
• fluoro elastomer e.g. for oil sealings
• powder coatings
• friction linings
• corrosion protection i.e. EP/PUR aqueous systems)
Acicular wollastonite technical specification:
SiO2: 50.5%; CaO: 45-47%; Fe203: 0.4%max;
P: 0.01%max; S: 0.01%max; Aspect ratio: 10:1 to 30:1
Moisture: 0.5%max; L.O.I.: 3%max
Mesh: 60/100/200/325/400/1250/3000 mesh 95-98% min passing throuah.
Packing: in plastic woven bag of about 25/50kgs net or in 1 m/t bag
as required.
