Elastomer distribution specialist Alliance Polymers & Services (Romulus, Michigan / USA; www.apstpe.com) has expanded its range of thermoplastic elastomers (TPEs) developed by Nantong Polymax Elastomer Technology (Nantong, Jiangsu / China; www.polymax.com.cn). The US company now also offers the “Maxelast” D-series for extrusion applications, which are claimed to be a cost-effective replacement for vulcanised rubber and EPDM.

Alliance says the grades can be co-extruded and are available from bags of 25 kg to truckloads. Typical applications include extruded glaszing gaskets and appliance seals, ladder feet, water stops and blown compounds for low-density seals. The grades are also suitable for automotive and construction window and door seals as well as solar products, Alliance says. Key characteristics of “Maxelast” D series include good weatherability, UV stability, long service life, weight reduction, reprocessability and recyclability. The Michigan-based group added that the material is easily processed and also boasts “superior” postshaping and sealing characteristics.

Polymax’s D-series of Maxelast TPEs are available in natural, black or transparent grades and in hardness ranges from 30 to 60 Shore A. Alliance says that when the grades are extruded or co-extruded into profiles, they can be miter-cut and heat welded for corner fastening products and applications. Some “Maxelast” D grades can also be foamed to achieve a smooth surface.
