ADDITIVES | ANTIOXIDANTS & STABILISERS New capacities


Above: Addivant’s Weston 705 liquid AO now has food


contact approv- als in Europe, China, and across the Americas


provide more momentum for this strategy. SK Capital Partners , the private investment firm that has owned Addivant since 2013, said in June that it had agreed to acquire SI Group. Headquartered in Schenectady, NY, SI Group


operates 20 manufacturing facilities on five conti- nents. At the close of the transaction, expected later this year, SK Capital will combine SI Group and Addivant (which itself makes not only antioxidants but various other additives, including antiozonants, inhibitors, polymer modifiers and UV stabilisers). Barry Siadat, a co-founder and Managing


Right: BASF is adding global capacity for its Irganox 1010 antioxidant at three plants, including a 30% expansion at its Swiss facility at Kaisten


Director of SK Capital, says SI Group has an excellent fit with the technologies and end markets of several SK Capital businesses, of which Addivant is one. “By combining the complementary strengths of SI Group and Addivant, we will be creating a global technology and industry leader in plastic, lubricant, oilfield, and rubber additives,” he says. Addivant continues to expand production capacity for Weston 705, especially as it hopes to tie up partnerships with two major Chinese polyolefin suppliers - Sinopec and Petrochina - in the near future. Production in China under licence by a production partner is set to begin in Q4. “Additional integration within the Weston 705 manufacturing process will be enhanced by making an intermediate in France and the future combination with SI Group is expected to bring further synergies,” Pavlik says. He also draws attention to Genox EP, a solid


phenol-free stabiliser that acts as both a primary and secondary antioxidant and which has been in the Addivant portfolio for some time “but which is only now resonating among suppliers of polyolefins. It also has possibilities in engineering thermoplastics.” Genox EPis 90% vegetable-based and is, Pavlik


claims, the best solution for preserving colour. He believes it is especially appealing in such applica- tions as fibres used in hygiene products. It is claimed to be five times more effective than more traditional stabilisation systems, but it is also expen- sive. Addivant is currently investing to improve production efficiencies, he says.

Addivant is not the only additives supplier adding capacity. Last October, Solvay said it would invest to double the capacity of its Technology Solutions global business unit’s high molecular weight HALS production facility in Willow Island, West Virginia, US. The core HALS products currently produced at the site are the foundations for the company’s Cynergy and Cyxtra polymer additive product families. The investment is for a second, fully independent HMW HALS manufacturing unit to complement the existing line at Willow Island and is slated to be operational by mid-2019. This July, BASF said it plans to increase global


production capacity for its antioxidant Irganox 1010 by 40% through production expansion projects at its sites in Jurong, Singapore, and Kaisten, Switzerland. New production in Kaisten should come online in 2019 and in Singapore in early 2021. The investment includes doubling capacity in Singapore by adding an additional production line that will be integrated into the existing production facilities. An increase of 30% at Kaisten will be achieved through debottlenecking. BASF is also investing in its McIntosh, Alabama,


US, site to improve supply reliability and expand capacity of Irganox 1010 and associated antioxi- dants. The company has not quantified that expansion.
