2016 preview | Polymers and additives
Right: Riverdale Global claims its liquid
blowing agents produce a more controlled foam
electrical/electronics. The new compounds will be on display with the full range of Radici products, from its high temperature resistant Radilon HHR and Radilon X-Treme to its Radistrong, Radilon A, S, D and DT metal replacement options, which include PA610 and PA 612 grades. Flame retardant options include the Radiflam HF halogen and red phosphorous-free products for the electrical and electronics industry and Radiflam S grades, which were selected for use in seating at five of the venues for the recent Rio Olympics. ❙

Riverdale Global will show a new series of liquid blowing agents for use with a wide range of resins that are claimed to provide improved dispersion and more controlled foaming action than pellet masterbatches, while being used at lower addition levels. The chemical blowing agent (CBA) formulations available in the new +Foam series of liquid additives include the standard exothermic azodicarbonamide CBA, an endothermic CBA, and a combination of the two. All are used at 0.5-1.5% letdown ratios, which are lower than levels typically required for pellet masterbatches. The company says the liquid additives can be used with polyolefins, polystyrene, ABS, PPO and other polymers. According to the company, because +Foam liquid
blowing agents avoid the heat history required for manufacturing pellet masterbatches and are more gently mixed into the base resin, pre-decomposition of the CBA is less of a concern. For users of +Foam products based on an endothermic CBA, there is also the added benefit of shorter cycle times since the CBA contributes less heat to the process. ❙

Below: SABIC will show its latest closure grades
SABIC will be showing the latest additions to its range of polyolefins for production of lightweight thin wall packaging and closures. HDPE CC860V is a new high purity grade developed for production of caps and closures for still water. Already in use by a number of leading water brands, the resin offers very good organoleptic performance, minimising any risk of flavour tainting or odours. Other grades targeting the caps and closures sector include HDPE AX7611, a bimodal HDPE with good organoleptics developed for production of caps for sparkling water and CSDs, and PP PHC28. The latter is focused on specialty closures for the chemical and household products sector and offers very good resistance to chemicals and impact. The company will also feature its Flowpact PP resin family, which
includes high MFI grades formulated for production of injection moulded thin wall packaging requiring high flow and stiffness. Flowpact resins are said to enable downgauging of designs while the high flow and fast crystallisation allows shorter cycle times to be achieved.
SABIC will be promoting its ISCC Plus-accredited
certified renewable polyolefins. Developed on mass balance principles (which factors in the environmental contribution of renewable cracker feedstocks, in this case waste fats and oils, to the total production chain), the company says production of PE and PP grades using renewable feedstock uses 84% less fossil fuel. ❙

So.F.TER will present its new PA6 Litepol engineering polymers with hollow glass microspheres that reduce the weight of plastic parts by up to 30% for automotive applications. The introduction of the Litepol B PA6 grades follows the approval last year of the Litepol range of PP compounds by FCA Fiat Chrysler Automo- biles. So.F.TER says the compounds provide weight reduction, good strength and shock resistance, shorter cycle times and good dimensional stability of moulded parts. Litepol can be used on standard injection moulding equipment and requires no additional technology investment. ❙

Solvay will launch two new additions to its range of Technyl PA polymers for the automotive sector – a new line of high heat resistant PA66 polymers for thermal management applications and a range of PA66 com- pounds with controlled halogen content for the electrical and electronic markets. The company will also use the show to introduce its
Technyl 4earth premium performance recycled PA66 grades. Developed from its Move 4earth sustainability programme, the new materials use PA66 recovered from automotive airbag tabrics and are said to offer perfor-
