HAR T77

Talc

HAR T77 is produced using a delaminating process developed by Imerys Talc.

HAR T77 is much more lamellar than other conventionally micronized grades and provides improved mechanical properties when compounded in polypropylene. Higher flexural modulus and HDT, better dimensional stability (low CLTE, shrinkage) are obtained versus conventional talc products, without impairing ductility of the molded parts.

HAR T77 is not white, but is nearly colorless, making it ideal for use in pigmented systems.

HAR T77 is delivered as spray-dried beads and has excellent flow properties for easy handling and high extruder throughput.
