Rhodia’s Technyl A 218W V30-grade polyamide has received the W270 certification for applications in contact with drinking water. Pertaining to aquatic micro-organisms, the certification is recognized by European and American regulatory authorities. The material is a 30% glass-fiber-reinforced polyamide 6.6 known for hydrolysis resistance and mechanical performance, with potential end-use applications in heating systems, pumps, valves, and similar components.

After more than 2500 hours of aging, no glass fibers appear near the material’s surface, and following 10,000 hours in an aqueous environment heated up to 95°C, Technyl A 218W V30 reportedly maintains up to 75% of its mechanical properties. Available in black and natural grades, Rhodia says the material also offers very good surface aspect.

The W270 certification is awarded by the Technologiezentrum Wasser (TZW) and means the material passed a series of tests featuring a micro-organism culture in an aquatic environment. Technyl A 218W V30 already complies with the WRAS, DGVW, ACS, and NSF drinking water standards for taste and odor, water limpidity tests, and migration. It also satisfies food-approved standards from European (EU Directive 2002/72/EC - 2004/19/EC) and American (FDA 21 CFR 177.1500, 178.3297) authorities.[email protected]
