Pittsburgh, Pennsylvania - Bayer MaterialScience llc has developed a new polycarbonate blend resin to replace SMA (styrene maleic anhydride) engineering resins, which offers "improved physical properties for automotive applications," including improved adhesion to polyurethane foams, the company said 15 July.
Bayer's Bayblend T88 GF-10 is a glass fibre-reinforced PC blend resin, which has been designed for applications such as instrument panel retainers, centre consoles, and other interior structural parts that previously used SMA resins, BMS said.
"We developed this resin to directly compete with glass fibre-reinforced SMA materials by offering improved physical properties," said David Siler, BMS interior accounts manager, adding that SMA will now no longer be available. "We can offer a seamless transition for decision makers in need of a replacement material which is available globally for current production model year interior parts," he added.
The replacement Bayblend resin, which offers a higher flow, improved surface cosmetics and better heat ageing performance, will be produced in North America for domestic auto manufacturers but will also be available globally to auto manufacturers outside the US from numerous BMS plants around the world, the statement said.
