Recently, BASF Engineering Plastics Co., Ltd. introduced a PBT/ASA blend - UltraduS4090GMll, whose warpage is lower than the low warpage product UltraduS4090GM13. Like the latter, the new grade also contains minerals and glass fibers. But it is said that it also has the anti warping performance that the existing PBT does not have. Its secret
【 Building materials network 】More recently, BASF engineering plastic The company has launched a PBT / ASA The warpage of the blend - UltraduS4090GMll is lower than that of the low warpage product UltraduS4090GM13. Like the latter, the new grade also contains minerals and glass fibers. But it is also said to have
The existing PBT does not have the warping resistance. The secret is to reduce the shrinkage difference at the injection molding part.
According to BASF, the old grade already has an excellent shrinkage difference (0.70/0.80), but the new grade has an amazing shrinkage difference of 0.95/1.0. In addition to easy demoulding and good appearance quality, the new grade is very suitable for large automotive interior trim parts.
