High heat polyester compound can replace PA in automobile structure application

At the earlier K show in Dusseldorf, Germany, SABIC, a material supplier, introduced Xenoy HTx resin, a high heat technology based on polyester, which can be used to produce light, impact resistant and high-performance automotive structural applications Xenoy products are alloys of thermoplastic polyester (PET or PBT) and polycarbonate Xenoy HTx resin is particularly important for today's automotive manufacturers, who need new polymer solutions to produce structural components that can withstand higher temperatures, including electronic coating lines that operate at temperatures above 180 ° C Related applications include BIW components, structural reinforcements, and battery protection systems for electric vehicles Xenoy HTx resin has two grades of unfilled and glass filled, and its weight is significantly reduced compared with steel and aluminum A new generation of thermoplastic materials from SABIC also provides a substitute for polyamide (PA) 66 compounds and alloys, which have been in short supply and fluctuating prices recently Amanda roble, global head of SABIC's automotive business, said: "we are firmly committed to investing in the future of the automotive industry by developing technologies that provide greater value, helping our customers meet new needs or extend performance limits A good demonstration of this commitment is our new Xenoy HTx resin portfolio, which responds to the needs of material solutions that allow structural reinforcement materials to pass through the electronic coating process and maintain their energy absorption and other performance attributes over a wider temperature range " The first products of this new high heat resin technology are the unfilled Xenoy HTx 950 and two glass fiber reinforced grades, Xenoy HTx 975 and Xenoy HTx 575 The impact tests of two honeycomb protective parts made of Xenoy HTx resin were carried out The results show that the material has a high energy absorption rate in a wide temperature range The left part showed good ductility and energy absorption at - 30 ° C, and the right part was tested at room temperature compared to the right part The unfilled resin is modified to absorb a lot of energy and bear plastic deformation in case of collision SABIC's goal is to be used as an alternative light metal solution in new safety applications, including side rockers designed to protect battery modules installed on the floor of electric vehicles In K 2019, SABIC demonstrated the structural lightweight capability of new technologies and designed a 3D printing prototype reinforced by rocker panel for battery side protection of electric vehicles When exposed to - 30 ° C, many competitive engineering plastics tend to become brittle and fracture under load Xenoy HTx can provide low temperature plasticity and very high elongation, thus achieving stable performance in this condition In addition, the new technology improves the fluidity, makes the design of complex geometry more free, and saves the cost of parts merging The hybrid honeycomb structure with Xenoy HTx can save up to 60% of potential energy compared with traditional all metal, multi-layer steel or extruded aluminum collision protection measures without affecting dimensional stability, rigidity and mechanical strength Glass fill grades are particularly suitable for high demand BIW structures, which must be able to withstand an electronic coating cycle of 30 minutes at temperatures between 180 ° C and 220 ° C It can also be used to produce other structural components that withstand high service temperatures, including front end modules, front brackets, and hood components Xenoy HTx has significant lightweight potential, which not only helps to improve the fuel efficiency of diesel locomotives, but also helps to offset some important weight added by battery modules of electric vehicles.
