Thermoplastic vulcanizates. (Materials).

Fully colorable NexPrene 1300 Series thermoplastic vulcanizates have been certified to meet ANSI/NSF Standard Class 61 for potable drinking water contact materials/fluid delivery systems. End use applications include fittings, piping and appurtenances. The approved water contact temperature is Commercial Hot (82[degrees]C or 180[degrees]F). With this NSF certification, the NexPrene grades are said to be suitable for use around the world in products such as seals, diaphragms, tubes, gaskets, o-rings, flanges, piping and other components where the materials are used in potable water applications or fluid delivery systems. The NexPrene product line, fully crosslinked EPDM/PP compounds, are designed to replace thermoset elastomers such as EPDM, conventional thermoplastic rubber and polychloroprene. Advantages over other materials are said to include lower cost processing, reduced cycle times and less scrap and trim, according to the company. NexPrene TPVs are said to have excellent compression set, are resistant to oil and heat as compared to vulcanized thermoset rubber, yet have the favorable characteristics of thermoset rubber materials, without the shortfalls of fatigue and abrasion resistance, according to the company.
