ADDITIVES | PLASTICISERS
reduce carbon dioxide output by up to 90% compared to conventional PVC resins and approximately 60% compared to traditional PVC plasticisers.
Synergist Galata Chemicals has developed new, highly efficient, mixed-metal carboxylate-type heat stabilisers designed specifically for use in flexible PVC compounds plasticised with the company’s primary bio-based and bio-attributed Drapex Alpha 200 and Drapex Alpha 215 plasticisers. One of the new synergistic stabilisers, Mark
3630, also boosted UV-light stability of and plasticiser permanence in compounds containing the Drapex Alpha plasticisers. “The combination of Mark 3630 with Drapex Alpha 200 significantly increased the time-to- exudation of PVC compounds compared to the conventional compounds with DOTP, DINP or TOTM and mixed metal carboxylate stabilisers,” said Patrick Evans, Global Director of Technology at Galata Chemicals. The synergistic stabiliser Mark 3620 was developed specifically for PVC cable compounds.
The company reported the additive more than doubled the Congo Red decomposition time of compounds with Mark 3620 and Drapex Alpha, while maintaining comparable volume resistivity in comparison to the cable compounds with conventional Ca/Zn stabilisers and phthalate plasticisers.
Although it depends on the formulation, the
high efficiency and synergism of the Drapex Alpha plasticisers and Mark 3630 or Mark 3620 often allow significantly reduced plasticiser and stabiliser loadings, said Peter Frenkel, a consultant for Galata.
