Future Considerations for Use of Wollastonite in Plastics

To maximize the performance of wollastonite as plastics performance requirements increase, the following points should be considered  

Low cost reinforcing filler Less expensive than milled or chopped glass fibers Better economics for filled plastics while giving strength improvements 

Binary reinforcement Cost effective combination Better balance of stiffness, 

Moderate specific gravity Ease of volume substitution Smoother reformulation transition and improved cost 

Lower cost than polymers Can replace more costly resins Maintain or improve desired properties over unfilled systems
