Micronized polyols for lead-free PVC stabilisation
Swedish speciality chemicals producer Perstorp (www.perstorp.com) has introduced a range of micronized polyols for Ca/Zn stabiliser systems that enables the production of lead-free PVC without affecting performance. “Holtac” polyols offer a range of melting points and hydroxyl numbers to allow customisation for specific PVC processing requirements.
The company said that equal performance can be achieved in dynamic heat stability tests to compare the performance of “Holtac” in Ca/Zn systems to lead.
