our expertise in innovative light stabilisers and other performance additives beyond China to meet the demands of a growing customer base worldwide,” says Junyi Lin, CEO of the company. “Our current investments extend across all levels, adding production, R&D, local sales and logistic capacities to get closer to upstream and down- stream customers and maintain security of supply.” The group’s current annual capacity of 80,000 tonnes for intermediates is being ramped up to more than 300,000 tonnes thorugh an expansion of its existing facilities at Suqian, in China’s Jiangsu Province. Three new plants are scheduled to come on-stream in 2022/2024 at Nanchong in Sichuan province and at Shengjin and Shengrui in Jiangsu. Capacity in finished products (UV absorbers, other stabilisers, and nucleating agents) will be more than doubled by an increase of 50,000 tonnes annually. UniteChem it is also adopting a new and more sustainable technology for synthesising benzotri- azole UV absorbers in a proprietary catalytic hydro- genation reduction process at its plant at Sugian. The company has been producing industry-
standard light stabilisers since 1997. Recently commercialised HALS products have included LS-2020 for fibres and webs of polyolefin and other polymer materials, and LS-119, intended mainly for agricultural, greenhouse and engineering polymer applications. Next year it plans to commercialise LS-4050, which is a low-molecular weight HALS for thick-wall items. Development of a HALS NOR grade for agricultural applications where high levels of pesticides are used is at the pilot stage. UniteChem already has a large warehouse at Antwerp in Belgium and has established a sales office at Düsseldorf in Germany. The company is also increasing its local technical customer support. Masterbatch major Ampacet is introducing
UVProtect, a new generation of UV stabilisers for polyolefin-based plastics. It has not revealed the chemistry used but says these are expected to find

application in sectors such as playground equip- ment, outdoor furniture, and vehicles. “Ampacet UVProtect 1248 efficiently protects the critical physical and mechanical properties of outdoor polyolefin-based plastic items with long-term exposure to UV radiation,” the company says. “UVProtect dramatically extends the life of plastics items, outperforming commonly used HALS with the same additive content. It achieves similar results as HALS with half the additive content, thus enabling reduction of the let-down ratio for better process control.” Polyolefins are not the only polymers to benefit
from stabilisation, of course. Among various performance-enhancing innovations being debuted by Brüggemann at K2022 are additives for polyam- ides that incorporate antioxidising functionality. BruggolenTP-H2062 and TP-H2217 are a new class of metal- and halogen-free heat stabilisers for reinforced and unreinforced polyamides in used in electrical and electronic applications. According to the company, the new grades do not cause corrosion of metallic components such as over-moulded sensors and have no impact on the polymer’s electrical properties. They support continuous service temperatures of 170°C with peaks to 200°C. BruggolenTP-H2217 is said to be particularly suitable for heat-stabilising halogen- free flame-retardant polyamides. Both additives are available as masterbatches.
