Dynamically stressed casing components in the automotive industry need outstanding mechanical properties: high burst pressure strength is essential to withstand alternating stresses. Good chemical resistance against corrosive media is also required.

components in automotive sector.
Engineering plastics supplier Evonik says it has a material up to the task in the form of its Vestamid HTplus M1035 P1 polyphthalamide (PPA) molding compound. The plastic was developed especially for use under these difficult conditions. The new PPA grade also reportedly achieves very good impact strength.
"We are pleased that the trials carried out by our customers confirm our own test results, which allow us to increase our customers' competitiveness even more," says Dr. Simon Ting, global business director at High Temperature Polymers.
In addition to the excellent mechanical properties, customers also benefit from the good flow behavior of Vestamid HTplus M1035 P1. As a result, the surface of the injection-molded parts tends to be smoother and defects-free.
The Vestamid HTplus product family was developed to replace classic metal applications. It is a semi-crystalline, polyphthalamide-based material that is resistant to high temperatures with a very good price-performance ratio. It combines high temperature stability with outstanding resistance to chemicals and exceptionally good mechanical properties.
