and specially engineered polymers. The EVSE platform also includes Avient’s Smartbatch combi- nation colourants and additives solutions that incorporate custom colours with functional additives in a single optimised solution. Additive technologies under the EVSE platform include flame retardant additives, anti-static and conductive additives, antimicrobial technologies, light spectrum management and scratch and mar-resistant additives. Colourant technologies offered under the EVSE solutions platform include UL 94 colourants, special effect colourants and Bio colourants and additives. Avient’s EVSE platform also provides support from product design through production which helps to achieve greater benefits throughout the development process. Avient says a North American electrical parts manufacturer with various locations was looking to update the process and performance of heavy-duty connectors and accessories it produced by reducing material rematching and rejection through more efficient pre-testing. It also sought to improve its processing efficiencies and colour consistency in its use of highly FR-filled and high-temperature resins. Also, under consideration was to further achieve regulatory compliance across multiple resin families, and to gain better supply chain control to manage scarcity of key engineering resins. Avient supplied the customer with its OnColor


UL 94 colourants as the solution. It offered eight UL 94 recognised sites in the US and Canada that performed comprehensive analytical, physical and mechanical testing. Avient’s EVSE platform helped the customer increase speed to market and expedite design timelines, while ensuring regula- tory compliance and security of material supply. SABIC introduced LNP Thermocomp WF006V, a


glass-fibre reinforced compound that can help facilitate the adoption of Laser Direct Structuring (LDS) antennas as a replacement to incumbent flexible printed circuit (FPC) antennas used in consumer electronics devices, appliances, and other electronic components. The LDS process allows an antenna design to be


directly transferred onto the three-dimensional surface of a part moulded from a polymer with special additive chemistry. The LDS process and technology supports part integration, minimises space requirements, simplifies prototyping, and enables cost-effective mass production of electronic components. LDS enables electronic component makers to create complex and miniaturised designs, accelerate production and reduce system costs. SABIC’s LNP Thermocomp WF006V provides a

SABIC says LNP Thermocomp WF006V has a tensile modulus more than two times higher


than that of unfilled PBT or PC resin


tensile modulus more than two times higher than that of unfilled PBT or PC resin, while delivering good surface quality, better chemical resistance and hydrolytic stability with lower warpage compared to traditional materials used in these applications. The material also features good impact resistance and laser welding capability and can be used for moulding small, thin-wall parts. According to SABIC, the new compound ad-


dresses the challenges of incumbent materials in electrical antenna applications, where chemicals used in the electroless plating process can erode some glass fibre-reinforced materials, causing the fibres to migrate to the exterior of the part where they affect surface finish. Other incumbent materials can warp due to their anisotropic characteristics, while excessive moisture absorption is a challenge for certain resins, which can result in poor dielectric stability. Sabic’s LNP Thermocomp WF006V com- pound has the potential to avoid yield loss, rework and subsequent extra cost, the company says. Outstanding heat resistance and exceptional thermal and electric insulation properties are imperative attributes in materials incorporated into lithium-ion batteries used in the burgeoning electric vehicle segment, as a safety measure against thermal runaway and accidental energy transfer. Lithium-ion batteries can generate excessive


heat due to thermal runaway when accidents and other disturbances occur, thus leading to a poten- tial fire, says engineering plastics producer Polyplastics. In a thermal runaway event, a lithium-ion battery cell can reach temperatures of 800-1,000° C, and the gas it ejects can reach 700-800° C. Structural insulative sheets and plates have been used to reduce energy transfer from one cell to another, however, those parts increase weight and consume space. Polyplastics has developed Durafide PPS 6150T73, a high-performance polyphenylene
