replacement,” says Michael Pilarski from PPA business management at BASF. BASF has also introduced a heat stabilised
Ultramid with heat resistance of up to 190°C for demanding environments. The PA 6 GF30 com- pound meets requirements for use in hybrid and electric powertrains. The company adds that engineering plastics must not only withstand high temperatures over a long period of time, but also prevent galvanic corrosion of electrical compo- nents. Heat resistance, good long-term use properties and weld resistance are the basic pre-requisites for components in current and future powertrains, whether in the internal com- bustion engine or hybrid and electric vehicles. With the development of heat-stabilised Ultramid B3PG6 BK23238, BASF is expanding its product portfolio of polyamides for the high-temperature range. The new P-stabilisation offers heat resist- ance of up to 190°C and prevents galvanic corrosion on electrical components due to its halogenide- and metal-free stabilisation, with a halogenide content of less than 50 ppm. The polyamide, reinforced with 30% glass fibres, also has good thermal ageing performance, as well as
vibration and hot gas welding properties. Tisan Engineering Plastics says that EV designers have turned to advanced polymers for electric insulation that do not compromise me- chanical and dimensional properties. For EV parts, specialty compounds with lower initial mould- shrink and warpage tolerances are preferred. They also have lower moisture absorption for dimen- sional stability and come in UL 94 V-0 grades for flame resistance. Tisan supports these efforts by formulating
