VESTAMID® HTplus, a substitute for metal in drinking water applications

Drinking water needs to meet the highest purity standards. However, on its way to the consumer clean water may become contaminated by heavy metals as it passes through metal pipes. VESTAMID® HTplus, a polyphthalamide (PPA) from Evonik Industries, can serve as a substitute for normal brass components in the future, thus ensuring a supply of unpolluted water.

VESTAMID® HTplus is renowned for its high durability, versatility, and ease of processing. The new VESTAMID® HTplus M1600 product series therefore meets the demand for plastics certified for drinking water with high dimensional stability and excellent mechanical properties such as rigidity and strength. In addition to the German KTW certification, VESTAMID® HTplus has received other national certifications such as NSF61, WRAS, and ACS.*

The VESTAMID® HTplus M1600 product series is ideally suited for applications in which metals have traditionally been used—for example as the base material for water filter housings or as a valve or regulator in sanitary fittings. In addition to corrosion resistance, the material offers advantages like design freedom and a reduction of the component weight, which in turn reduces component costs by up to 50 percent.

"We are continuously enhancing our product portfolio," says Dr. Nina Hoppe, Business Director VESTAMID® HTplus. "Thus, we ensure that we not just meet our customers’ current requirements but also their future needs."
