The company said the azelaic acid component is produced by Matrica using European-origin vegetable oils, resulting in a 38% carbon content. The additive can replace dioctyl sebacate (DOS) and dioctyl adipate (DOA) in low-temperature applications in wires, cables, flexible hoses, films, and packaging. The com- pany said it has good weather resistance and electrical insulation perfor- mance, plasticising efficiency, low volatility, and a low migration rate. TekniPlex Healthcare

compounds that the company says use resins and plasticisers manufactured with renewable energy and bio-attributed classification, certified by ISCC Plus. The compounds are drop-in replacements for traditional PVC medical-grade compounds and are produced in Northern Ireland. “As the healthcare industry increasingly empha- sises eco-friendliness and carbon footprint reduction, TekniPlex Healthcare’s bio-based, medical-grade PVC compounds enhance sustain- ability profiles without sacrificing the reliable performance for which traditional PVC compounds are known,” the company reported. The company says the new compounds can
reduce carbon dioxide output by up to 90% com- pared to conventional PVC resins and approximately 60% compared to traditional PVC plasticisers.
Synergist ability Galata Chemicals has developed mixed-metal carboxylate-type heat stabilisers 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 and plasticiser permanence in compounds containing the Drapex Alpha plasticisers. “The combination of Mark 3630 with Drapex Alpha 200 significantly increased the time-to-exu- dation 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.
Although it depends on the formulation, the
high efficiency and synergism of the Drapex Alpha plasticisers and Mark 3630 often allow significantly reduced plasticiser and stabiliser loadings, said Peter Frenkel, a consultant for Galata.
