VESTAMID® HTplus —A High Performance Polymer as a Substitute for Metal

VESTAMID® HTplus, a new member of Evonik Industries’ VESTAMID® family, has been specially developed as a substitute for metal in classic metal applications. VESTAMID® HTplus is a polyphthalamide (PPA) based semicrystalline material that is stable at high temperatures; it offers an excellent price-performance ratio.

Classic metal parts are increasingly being replaced by parts made of plastic, which have comparable mechanical properties at lower unit cost. In addition to high chemical resistance—as is required, for example, in fuel systems—molded parts made from VESTAMID® HTplus offer high dimensional stability and excellent mechanical properties such as rigidity and tensile strength. VESTAMID® HTplus is therefore ideally suited for use in classic metal applications, for example, as a base material for pump and filter-system housings. In addition to corrosion resistance, reduced component weight, and the resulting reduction—by up to 50 percent—in component costs, the greater design freedom offers several other advantages.

As a thermoplastic material, VESTAMID® HTplus can be economically processed on standard injection molding machines. The finished parts can generally be used without further downstream processing. On the basis of its many years of expertise in the area of extrusion, Evonik's High Performance Polymers Business Line also develops extrusion-grade PPA molding compounds.

In addition to polyphthalamide, Evonik has also been producing polyamide 12, polyamide 612, and polyamide 12 elastomer molding compounds (PEBA) under the VESTAMID® brand name for about 40 years and, more recently, polyamides based on renewable raw materials. Many reputable automotive manufacturers have been using the well-known materials for decades. Evonik is the leading manufacturer of polyamides for multi-layer tubing systems in motor vehicles.
