Thermoplastic Elastomers For a Safe and Healthy Environment
This October HEXPOL TPE will bring its portfolio of Thermoplastic Elastomers to Friedrichshafen when the international plastics industry meets once again for the Fakuma exhibition. In Hall B1, Booth 1217, the Global TPE specialist will present new and expanded products developed to meet stringent industry standards and emerging demands in the consumer, medical, packaging and automotive interiors markets.
“From concept to realisation, we want to make things easier for our customers,” says Peter Ryzko, managing director at HEXPOL TPE’s German site. “We recognise that our customers operate in diverse markets with complex and varied demands. In our product development we not only have to consider the properties of the TPE compound, it is also essential to have a deep understanding of specific regulatory requirements and aspects. Our customers are looking for highly customisable materials, originating from trusted raw materials which are compounded under well-controlled conditions, thereby making it easier for their products to address industry standards. At Fakuma we’ll show how we do this is on our daily work and present products and application expertise that meet these challenges”.
Among the technologies presented will be Dryflex Thermoplastic Elastomers for automotive interior applications such as floor mats, cup holder liners, fascia mats and HVAC components. These compounds are designed to minimise emissions from volatile organic compounds (VOCs) and help manufacturers and OEMs address demands for vehicle interior air quality (VIAQ) issues. The Dryflex TPEs display low fogging and low odour performance, including grades with results ≤ 3 in odour standards such as VDA 270. According to gravimetric fogging standard DIN 75201 they have condensate < 2 mg and in thermal desorption analysis VDA 278 they achieve VOC results < 500 µg/g and Fog < 1500 µg/g.
A new development in the Mediprene family of TPEs for medical applications is the introduction of several grades for solvent bonding. “Many customers are today joining tubes with injection moulded components, such as connectors, by solvent bonding. Traditional TPS based formulations do not bond well with solvent – cyanoacrylate glue with or without primer is an alternative to achieve high bond strength in these situations,” says Niklas Ottosson, technical manager – medical, HEXPOL TPE. “However, in addition we have developed a range of Mediprene TPE compounds which achieve high bond strength when applying solvents such as cyclohexanone.” Representative Mediprene grades have passed cytotoxicity tests according to ISO 10993-5 and biocompatibility tests according to ISO 10993-10 (Intracutaneous Reactivity), ISO 10993-11 (Acute Systemic Toxicity) and USP Class VI. Mediprene solvent bondable TPEs for injection moulding are available in hardness’ from 70 Shore A to 45 Shore D and can be further expanded based on application requirements.
With increasing demands from consumers for the polymer industry to deliver sustainable alternatives to traditional fossil based products, another growing area for HEXPOL TPE is the Dryflex Green family of biobased TPEs from renewable resources. These compounds are opening up previously unreachable design solutions to the biobased thermoplastic market by covering a wider range of hardnesses while incorporating high levels of renewable content. Typical applications include household products, sports equipment, construction profiles and automotive mats. HEXPOL TPE has further extended the range to include even softer grades, with new compounds available from 15 Shore A through to 55 Shore D. The Dryflex Green range includes grades with biobased content over 90% (ASTM D 6866), achieved by use of truly sustainable raw materials and feedstocks such as sugarcane, with recognised certifications such as ISCC+ and can derive from raw materials such as polymers, fillers, plasticizers or additives.
