Wollastonite 1250mesh
Properties:
Wollastonite’s chemical composition is CaSiO3, It’s acicular powder of Calcareous metasilicate mineral,The crystal system Tri-angled crystal of fine plate form crystal,the aggregate is radial or fibrous,It is white in color with a light gray hue and a glassy luster. Wollastonite has needle-like, fibrous crystal morphology with high whiteness and unique physicochemical properties,with good acid,alkali and chemical resisitence.
Technical Data：
Item | Standard |
SiO2，% | 49.0±2.0 |
CaO，% | 46.0±2.0 |
Fe2O3，% | ≤0.2 |
Moisture，% | ≤0.5 |
Linear expansion | 6.5×10-6 |
pH | 7-9 |
Oil Absorption，g/100g | 18-30 |
Whitenss，% | ≥90 |
45μm Residue % | ≤0.5 |
Application：
1. It is used to fill the foaming Makeup puffs, increase the weight of the sponge, and whiten and strengthen.
2. As a plastic filler, it is mainly used to increase tensile strength and flexural strength and reduce costs.
3. It can reduce the production cost of rubber products and improve the mechanical properties of rubber.
4. Bright color and high reflectivity, suitable for producing high quality white paint as well as clear transparent colored paint.
5. In the paper-making industry, wollastonite powder can be used as a filler and plant fiber composite into a paper-making composite fiber to replace part of the plant fiber.
Package：
In plastic woven bag with net weight of 25kg each
