US-based Vapur, a designer of flexible, reusable, handheld products, has developed a custom cap for a collapsible, reusable water bottle made of a thermoplastic elastomer (TPE) from Kraiburg TPE. The new Anti-bottle, designed to stand upright when full and folded or even rolled when empty, is also Bisphenol A (BPA) and phthalate free.
Vapur teamed with HQC Inc, a manufacturer of high quality custom injection and insert molded products in Chicago for medical and packaging companies to produce the bottle. Kraiburg TPE, brought in by distribution partner Chase Plastics, took part in the development process and created a customized technical solution for Anti-bottle’s cap.
Thermolast K TF4BNB, one of Kraiburg TPE’s Thermolast K FD/n series compounds, was selected for this particular application because is compliant with food contact regulations in the USFDA as well as EU Regulation 10/2011, according to the manufacturer. This TPE is halogen free, has a 45 Shore A durometer, and is recyclable.
Thermolast K TF4BNB is also latex and PVC free. It can be overmolded to polypropylene (PP). The company notes that the compound fit for this application because of its environmental and consumer appeal.
