High strength fire retardant V0 grade sheet molding compound
SMC5342 is a sheet moulding compound based on unsaturated polyester resin. The product is glass fibre reinforced and contains mineral fillers. The material is compression moulded in heated steel moulds. It is recommended to work with chrome plated tools. It does not contain any halogens nor any candidates from the REACH SVHC list.
General purpose SMC for electrical applications. Fire retardancy: UL 94, V-0 (3 mm)
SMC5342 is produced in a standard width of 1000 mm. It is supplied on rolls holding up to 1500 kg. It is possible to have it folded and packed in cardboard/wooden crates. In any case a styrene barrier film wrapping is being used. For alternative packaging please contact our technical service team. Available in all colours.
