MOSCOW (MRC) -- BASF is one of the first plastics manufacturers to expand its PBT (polybutylene terephthalate) product line by a new special grade optimized for the production of air-tight coffee capsules that retain the aroma, as per the company's press release.
This engineering plastic goes by the name Ultradur B1520 FC (FC: food contact) and it combines excellent barrier properties against moisture and oxygen, while above all, containing the aromas, without a need for any additional complex coatings. This distinguishes these Ultradur capsules from other injection-molded capsules, which are usually packaged individually, as well as from multilayered thermoset capsules. Injection molding is the adequate processing technique for the production of upscale coffee capsules with their exacting design.
With its food-contact certification, this new grade is suitable not only for coffee capsules but also for thin-walled injection-molded packaging for cosmetics and food products.
Besides, as the first manufacturer of thermoplastic polyurethane (TPU), BASF has successfully optimized the material so that it can be applied extensively and unpainted on the vehicle exterior. The automotive manufacturer PSA Peugeot Citroen uses the new TPU grade Elastollan AC 55D10 HPM (High Performance Material) for cladding the Citroen C4 Cactus with so-called Airbumps. This world first is the result of many years of development work between the French automotive manufacturer, the supplier Rehau of Switzerland and BASF. Airbumps are large air-filled cushion bumpers in contrasting colors: They are fitted on the sides as well as on the front and rear of the vehicle, protect the car exterior from impact and scratches and give the vehicle its distinctive look.
The trend towards miniaturization and thinner walls in electrical and electronics applications continues apace and BASF has developed multiple product families with new and improved UL listing.
The flame-resistant Ultradur types B4406 G2/ G4/ G6 (polybutylene terephthalates) are classified according to UL94 V-0 from a wall thickness of 0.4 mm. Now the listing has been expanded to include the relative temperature index (RTI) for 0.4 mm. The high RTI values for dielectric strength remain consistently high at 140 C. The product family therefore is especially suitable for increasingly powerful electrical plugs, power strips and housing components. These can now be produced with lower wall thicknesses.
The newly developed Ultramid A3U42G6, too, a halogen-free, flame-retardant, glass fiber-reinforced polyamide meets fire protection class V-0 according to UL94 from a wall-thickness of 0.4 mm. The heat aging resistance was significantly improved over glass fiber-filled polyamide types such that the material, with an RTI value for dielectric strength at 140 C with a 0.4 mm wall-thickness and even 150 C at 0.75 mm and more, is suitable for use at higher temperatures. The new Ultramid A3U42G6 is also distinguished by extremely easy processing with reduced deposit formation. The flame retardant system shows no migration effects and thus ensures higher-quality component surfaces. Possible application areas include control, contactors and connectors.
Ultraform S2320 003 PRO (polyoxymethylene), specially developed by BASF to meet the particular requirements of the medical technology sector, has made an impressive debut in the Skin Stretcher product from BioWim GmbH, primarily for its reduction of the friction between touching functional components, the combination of high rigidity with outstanding resilience as well as very good flowability. The material also provides demonstrated compliance with international standards for the use of plastics in medical technology. Skin Stretcher is an implement for treating or closing large wounds after operations or accidents.
Rethinking Materials – this is the thought experiment posed by BASF and the design agency DING 3000 which led to the "Concept 1865" bicycle - a bike that takes on the appearance of the penny-farthing bicycle that was popular at the time of BASF's founding in 1865. The electric bicycle incorporates over 20 different, in some cases very innovative, plastics, from polyurethanes to thermoplastics, foams, epoxy resins and composite products that BASF subsumes under the heading "Performance Materials."
As MRC wrote before, in July 2014, BASF Shanghai Coatings Co., Ltd. inaugurated its new automotive coatings plant at the Shanghai Chemicail Industry Park in Shanghai, China. The expansion of its automotive coatings production capacity with an investment of around EUR50 million further strengthens BASF’s presence in China and its position as a leading coatings supplier to the automotive industry.
BASF is the world’s leading chemical company. Its portfolio ranges from chemicals, plastics, performance products and crop protection products to oil and gas. BASF had sales of about EUR74 billion in 2013 and over 112,000 employees as of the end of the year.
