Knocking back, not knocking over, a glass of cold, clear water on a sweaty summer day just became easier with Brita’s new Elemaris table water filter, which has a coating of Bayer MaterialScience AG’s slip-resistant thermoplastic polyurethane (TPU) Desmopan DP 6386A on the handle and the four rounded sections of the filter pitcher’s base.

Manufacturing the filter pitcher involves a two-component lathe tool using hard/soft technology and injection molding. The transparent base of the pitcher is molded from a styrene acrylonitrile copolymer (SAN) before the soft TPU is overmolded onto the base using hot runner technology.

It melt solidifies very rapidly, making production fast and cost-effective and cutting cycle times by up to 35 per cent compared to standard grades of Desmopan. Desmopan DP 6386A has a 86 Shore A hardness, and won’t degrade when repeatedly exposed to water, microbes and typical household chemicals.

As a result, DP 6386A barely shows any signs of wear and tear even after many years of use.
