High aspect ratio HAR® talcs talcs are produced using a patented delaminating process which results in significantly higher aspect ratios than conventionally micronized talcs. Proper processing and dispersion of HAR® talc in plastic compounds generates excellent orientation of particles during injection molding, which maximizes stiffness, HDT and dimensional stability of the resulting part.
- - Higher flexural modulus
- - improve HDT
- - better dimensional stability
