16-Dec-08

Rhodia has obtained the W270 certification regarding aquatic micro organisms for its Technyl® A 218W V30 grade, a 30% Glass Fibre reinforced polyamide 6.6. The certified grade shows a superior hydrolysis resistance to standard polyamide 6.6 glass filled grades demonstrated by the absence of glass fibres appearing near the surface even after more than 2,500 hours of ageing. In addition, after 10,000 hours in an aqueous environment heated up to 95°C, the grade preserves up to 75% of its excellent mechanical properties - more than 15% higher than traditional materials. Rhodia's Technyl® A 218W V30 has been successfully homologated for use in customer's various end-use applications and is particularly designed for use in heating systems, pumps and valves and similar applications. The W270 certification, awarded by the Technologiezentrum Wasser (TZW) - which is the reference for water biological analysis, - rewards this grade for having passed successfully a series of stringent tests regarding the micro organism culture in an aquatic environment. Technyl® A 218W V30 has already complied with drinking water standards WRAS*, DGVW*, ACS* and NSF* o Taste and odour tests o Water limpidity tests o Migration tests The grade also complies with food approved standards from European authorities (EU Directive 2002/72/EC - 2004/19/EC) and American (FDA 21 CFR 177.1500, 178.3297) o Food approval status of all additives used in the formulation.
