Product Data Sheet H Series superfine(Compaction type)
This product is a highly pure white talc. Due to its high lamellarity, extreme fineness, uniform particle size distribution, high whiteness, good dispersity, excellent abrasion resistance and scratch resistance, easy to feed, good thermal stability and able to reduce the amount of other additives, it is suitable for reinforcement of modified plastics, it is recommended for polypropylene automotive exterior parts, interior parts, bumpers and dashboard products of high-end auto. Due to the compacted form, higher compounding throughput that can be achieved, it can be used as a nucleant in semi-crystalline polymers.
