Rhodia Engineering Plastics introduces a range of high performance hydrolysis resistant products to meet demanding water regulations
Water Regulations are national requirements for the design, installation and maintenance of plumbing systems. Their main purpose is to prevent the contamination of drinking water
Brussels, June 8, 2004 - Rhodia Engineering Plastics have developed new grades based on Polyamide 6.6 that have been approved by regulatory authorities (WRAS, DVGW) for use in applications where there is contact with drinkable water. These grades show an excellent resistance to hydrolysis and are specifically designed for use in heating systems, electro-valve bodies and similar applications.
DVGW (GERMANY) materials approved
• TECHNYL® A 216 V30 NATURAL: water use at 23°C and 90°C.
WRAS (UK) materials approved
• TECHNYL® A 218W V30 Natural: cold and hot water use up to 85°C.
• TECHNYL® A 218W V30 BLACK FA : cold and hot water use up to 85°C
To achieve these water regulatory accreditations a series of difficult tests had to be overcome. These include;
• Food approval status of all additives used in the formulation.
• taste and odor tests
• water appearance tests
• Aquatic micro organism growth tests
• Migration tests
The accreditation at the water regulatory bodies was just the final step in the development process. The first step was to ensure that the materials technical characteristics, linked to mechanical retention in heated aqueous environments, were able to withstand the harsh environments in which they were to be used.
Technyl® A 218W V30 natural, Technyl® A 218W V30 black FA and the Technyl® A 216 V30 natural have been successfully homologated for use on final parts for a variety of different applications. These grades combine stiffness and mechanical strength, together with outstanding hydrolysis thermal performance to meet the demanding needs of the electro-valve and heating systems industries.
In particular The Technyl® high performance hydrolysis range provides the following characteristics;
• High strength and stiffness retention in heated aqueous environment.
• Excellent impact resistance
• High chemical resistance
• Excellent surface finish
Regulatory certifications are available upon request.
