PP in vehicle manufacturing. This supports vehicle recyclability – and means that variants based on recycled raw materials (PIR and/or PCR) are also available. With its Tedur GF IM, Mocom introduces two new types that combine the properties of conven- tional PPS with enhanced impact and notched impact strength, making them suitable for demand- ing applications. These new compounds – with glass fibre (GF) and impact modifier (IM) – are an “economically and technically attractive alternative to PPA”, it says.


Battery materials At last year’s Battery Show North America in Detroit, Celanese highlighted its latest advances in materials for electric vehicles (EVs). These included Zytel HTN FR53G50NH, a new high-temperature polyamide for battery module end plates and other structural components. It offers high stiffness, reduces warpage and im- proves noise, vibration and harshness perfor- mance, while maintaining tensile strength in high heat and humidity environments, it says. At the same tine, Zytel PA 80G43EF is an electrically friendly polyamide with good stress crack resistance, designed for overmoulded automotive electrical and electronic applications such as transmission control units, connectors and sensors. It can replace thermoset epoxy without needing retooling, making it an efficient, cost-effec- tive solution. The full portfolio includes various electrically friendly grades with higher volume resistivity and dielectric strength compared to standard inorganic stabilised grades. Meanwhile, Fortron PPS 1140L4 is engineered to withstand high temperatures and resist hydrolysis, making it suitable for battery coolant systems and other thermal management modules in EVs. It supports thinner wall designs, enabling more compact and efficient components, and serves as a drop-in replacement for other PPS materials without the need for retooling.


Part protection Sabic has introduced LNP Thermocomp WFC061I, a non-brominated/non-chlorinated flame retardant (FR) that can be used in electric vehicle control units (EVCUs). The new material is suitable for the housing of these applications, providing good structural performance for protecting sensitive electronic parts from fire/smoke, impact, moisture and other threats. The compound can replace metal in EVCU

covers to reduce weight and expand design freedom. Alternatively, it can replace polymers that use halogenated FRs, which can affect the environ- ment. Other advantages include colourability, low warpage to increase yield and high optical trans- mission for precision laser welding. Sabic says the glass fibre-reinforced compound is the world’s first laser-weldable FR polybutylene terephthalate (PBT). “The EVCU, which manages an EV’s electrical systems to ensure peak efficiency, relies on high-performance materials,” said Jenny Wang, director of formulation and application for APAC at Sabic polymers. “Based on our broad understanding of automo- tive power engineering trends and requirements, we developed this new PBT compound to help protect the EVCU and optimise its reliability and functionality,” she added. The material provides the high optical transmis- sion (20% at 3mm thickness) for laser welding, which joins two plastic parts without adhesives, chemicals, fasteners or vibration. The laser energy passes through the material to the surface of the absorptive material, where it generates heat at the interface and melts the plastic. Its compatibility with laser welding helps manufacturers speed up and simplify assembly, says Sabic.


Bio-based LCP Sumitomo Chemical has developed a mass production technology to make liquid crystal polymer (LCP) from a bio-derived monomer. It aims to obtain customer certification by the


end of the 2026 financial year and begin supplying the product from 2027. LCP is an engineering plastic with high heat- and


fire-resistance. It is used in a variety of electrical and electronic components. In the new manufactur- ing process, Sumitomo has adopted a ‘segregation approach’ that separates biomass materials from others during production. This enables precise control of the biomass content and can clarify how much is included in the product. It also uses the mass-balance approach.
