Stellar 420 is bright, high purity, very platy talc recommended for improving stiffness, HDT and dimensional stability in general purpose plastics applications requiring higher brightness.
Stellar 420 is used mainly in commodity plastics applications, especially in polypropylene, where maximum reinforcement can be achieved at loadings as high as 20% to 40% while also achieving good long-term thermal stability(heat aging).
