Wollastonite for Plastics, Calcium Sillicate

Production Capacity: wollastonite
Wollastonite for Plastics, Calcium Sillicate

Product Description

Our wollastonite's reinforcing needle-like structure, thermal stability and conductivity, low resin demand and chemical purity make it an ideal additive to polymer formulations. It is used in an array of thermoset, thermoplastic and elastomeric applications including:
Nylon 6 and 66/high temperature PA compounds
1\PP/CTPO/HDPE
2\polyurethane
3\LCP/PBT/PET
Our suite of chemically surface modified products meets the demand for improved composite properties. Coupling agents like organo silanes and other additives used with our wollastonite improves the interface between the filler/reinforcement and the polymer.

Benefits of Wollastonite in Plastics
Whether you're designing a new composite, or updating an existing formulation, our wollastonite products offer a significant advantage over other fillers and reinforcements.
1\improves dimensional stability
2\increases flexural modulus
3\improves heat distortion temperature
4\improves mar, scratch and gouge resistance
5\reduces shrinkage
Offers heat sag resistance and improved heat aging
Provides excellent balance in impact and stiffness
Offers knit line reduction
And when compared to other fillers and reinforcements, our products also yield:
1\higher loadings
2\improved product flow, faster mould cycles
3\product uniformity
4\scrap reduction
