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
Advantages
a. good compatibility.
b. Excellent Stability and products meets clients requirement
absolutely
c. Excellent performance on physical properties
