US resin maker Trinseo (Berwyn, Pennsylvania; www.trinseo.com) said it has developed flame-retardant PC and PC/ABS resins that are manufactured without the use of per-and polyfluoroalkyl substances (PFAS) or halogenated additives, with options of recycled content.

Its flame-retardant introductions include its Emerge PC 8600PV and Emerge 8600PR grades, which are UL94 VO rated at 1.5 mm for all colours, and offer high-temperature resistance, UV resistance, superior impact resistance, along with dimensional stability, a wide processing window, and glossy/matte finishes, the company said. 

Trinseo also introduced Emerge PC/ABS 7360E65, a flame-retardant grade in which halogenated additives are not used in the manufacturing process. This grade, which has 65% recycled content, is UL94 V2 rated at 0.5 mm for all colours, and is ideal for thin-wall applications. It offers high flow, dimensional stability, thermal stability, UV resistance, and a wide processing window, the company added.

Emerge 8600PR and Emerge 7360E65 use post-consumer recycled substrates that facilitate waste and carbon-footprint reduction, and recycling while maintaining performance similar to virgin materials. The new materials maintain their flame-retardant properties and their resistance to heat, oil, stains, grease, and water. Trinseo said the resins will be introduced at the Chinaplas 2024 tradeshow taking place from 23 to 26 April. The grades will be first launched on the Asia-Pacific market and are suited to a variety of applications including IT equipment, electronic and electrical products, battery chargers, and voltage stabilisers, the company said.
