hardness levels from 40-85 Shore A. Formulations can be customised. The company also announced the introduction
of a line of PTFE-free and non-halogen flame-re- tardant additives. There is growing pressure to ban PFAS due to environmental concerns prompting manufacturers to search for alternative materials. Avient’s new Cesa flame retardant additives are formulated without PTFE and are halogen-free in accordance with the IEC 61249-2-21 standard. Suitable for a variety of PC grades, including those with recycled content, these additives can help achieve GWFI temperatures up to 960°C according to IEC 60695-2-12 testing protocols and are provided in the form of concentrates so producers can combine them with colours and other additives. Eurotec says it is constantly improving and
expanding its solutions for both interior and exterior parts. Emission characteristics are impor- tant parameters in interior applications and many OEMs have limited these values with standards. For example, in VW interior applications, a VW 50180 standard is required. For its 30% glass-filled Tecomid PA6 grades, PV 3900 odour characteristic, PV 3015 fogging, PV 3341 emission of organic compounds tests were carried out by an accredited test laboratory in Germany and all results were in line with requirements of VW 50180 standard. PA66 with 30% glass fibre materials are widely used for pedal brackets or housings, while Tecomid Eco NA43 GR30 BK005 HS/M65I (PA66 GF30) exhibits an almost identical mechanical profile to prime materials and has a minimum 65% recycle content. Surface quality and high impact properties are
key for PC/ABS blends where proper sourcing, formulation and process technology are critical when using recycled materials, says Eurotec. Tecotek Eco BC44 UF65 BK013 MB/M65C (PC/ABS, unfilled, impact modified, heat stabilised, black, 65% post-consumer recycled grade) is in-line with all required material properties. Sunroof cable
harnesses need high flexibility, toughness, strength, and efficient processing. Here, Tecomid NB60 NL PM (PA6-I) can be designed using a special formula- tion giving it 1,500 MPa tensile modulus and 85 kJ/ m2 izod notched impact resistance. Tecodur PB70 GR30 BK009 CE01 (PBT GF50), which has especially high UV stability, can be used for side mirror applications due to a combination of high mechani- cal properties and low moisture absorption. Meanwhile, Tecomid NC40 GR30 BK047 CE (PA6.6/6 GF30) exhibits excellent UV performance, good surface quality, and mechanical properties.
