high impact performance especially at low tem- peratures. The company has since divested some of its businesses in additives used in the manufacture of PVC profiles, pipes, and packaging, as well as engineering plastics, to Indian group Praana as it refocused its portfolio. The divestment specifically concerned Arkema’s impact modifiers and process- ing aids businesses, and covered the global scope for methyl methacrylate butadiene styrene (MBS) copolymers as well as the European and Asian scope for acrylic copolymers (AIMPA). These activities, part of Arkema’s Coating Solutions segment, generated €44m sales in 2024, and the project entailed the divestment of the Vlissingen production facility in the Netherlands which employs 50 people. The facility is now operated by Praana group company, Galata Chemicals , which produces stabilisers and plasticisers at various operations located around the world, including the US, Canada, India and Germany. Vishal Goenka, Vice Chairman of Praana Group,
said: “This proposed acquisition strengthens Galata Chemicals’ portfolio with complementary plastic additives technologies that enhance impact performance and process efficiency in PVC and composite applications. It supports integration-led growth, deeper customer engagement, and scalable value creation across core end markets.”
Colour hold The prevention of yellowing is one of the most common challenges in PVC manufacturing and application. It is primarily caused by dehydrochlo-
rination due to heat or UV exposure, leading to the formation of conjugated double bonds (polyenes) that discolour the material. The choice of stabiliser is considered the first line of defence against thermal degradation. Novista Group highlighted its calcium-zinc stabilisers as providing excellent early colour hold and superior whiteness in finished products, acting as environmentally friendly alternatives to lead. The company said: “For high-end construction
materials, compounding different stabilisers can create a synergistic effect. For example, in premium window profiles, combining Ca-Zn stabilisers with a small amount of organotin can significantly enhance thermal stability and minimise yellowing.” Novista, a chemical manufacturing complex established in 2002 and headquartered in Weifang, Shandong Province, China, also reiterated how inadequate dispersion of stabilisers can create weak spots within the PVC resin matrix where degradation begins and recommends using high-speed mixers to ensure that all stabilisers and antioxidants are adequately distributed. PVC plasticisers are the subject of a feature article in Compounding World August 2026.
