Synthetic Hydrotalcite
Introduction:
baoxu synthetic Hydrotalcite BX SH is a kind of aluminum and magnesium synthetic hydroxide, and it’s status of ultramicro powder and has good dispersibility in processing. synthetic hydrotalcite is mainly used as an acid scavenger /absorber in polyolefin processing. It has the appearance of white powder and is insoluble in water.
CAS No.: 11097-59-9
Synthetic Hydrotalcite Applications:
As an acid scavenger, BX SH has the advantages of a high capacity of the acid absorber, no separate out, greater heat stability than traditional Calcium Stearate, it has favorable applicability with plastic additives in processing, and the polymer will not occur yellow-turning. The product mainly used as:
1. Acid absorber/scavenger in polyolefin processing;
2. UV absorber in agricultural PE、PVC、EVA;
