PVC PLASTICISERS | ADDITIVES


In addition, Varteco provides technical and commercial


support, assisting customers in product validation, formula- tion optimisation, and industrial implementation. Together, the trio of companies hope to expand a technology platform that they say has already demonstrated commercial perfor- mance in other regions, creating new opportunities for compounders, converters, and brand owners. The initiative also aligns with global decarbonisation efforts, contributes to carbon footprint reduction, and advances the sustainabil- ity profile of flexible PVC applications by transferring expertise accumulated by all three companies through years of development and successful industrial deployment.


Rodent attacks Amid a perception that widespread use of soy-based formulas would increase rodent attacks on PVC electrical wires, the assessment of rodent damage in PVC wires plasticised with bio-based systems has been a focus area for Innoleics, whose director Jacyr Quadros delivered a presentation on the topic at AMI’s Polymers in Cables 2026 event held in Cleveland, US. Quadros pointed out that formulations in Brazil have shifted to bio-based plasticisers without an increase in reports of rodent damage. And in the US, he said PVC formulations have not widely shifted to bio-based, suggesting that the root cause of the problem lies more with the often softer and thinner wire often used in cars than a change in plasticiser. Innoleics has sought to provide a science-based answer by having a third-party lab conduct a rigorous study comparing plasticisers. During the presentation, he re- vealed the results of tests showing fossil-based wire coating is significantly more degraded by mice compared to bio-based and hybrid alternatives. It is theorised that the reasons for this are the differences in organoleptic charac- teristics, with bio-based plasticisers having a more bitter and less appealing taste compared to fossil-based varieties. Quadros also noted that the new generation of bio- based plasticisers has addressed the issues of resistivity that were a concern with the earlier generation. He said that all properties of the new product are on par with DINP. Brazil has not transitioned all of its PVC production to bio-based plasticisers, but the country actively uses and produces them. Rather than a single government mandate replacing all petroleum-based options, this shift is driven by market demand, niche applications, and sustainability goals.
