Derivatives of Polyglycerols

Additives with high percentage of bio-degradable and vegetable origin carbon, used as lubricants, plasticizers and release agents for various industrial sectors. Nachmann has developed some new plasticizer / lubricant additives and release agents based on esters of polyglycerols.

Thanks to the high presence of free hydroxyl groups in the polyglycerol chain, some extremely stable polymeric esters have been developed, having excellent lubricating properties.

Furthermore, their polymer structure ensures a low outcrop of the product and, consequently, a very low interference with the aesthetic properties of the final article.

The esters of polyglycerols can be dosed directly into the extruder or mechanically mixed with the polymer in granules or powder.

The addition level percentage depends on the specific application.
