BASF now offers a suite of engineering plastics exclusively designed for drinking water contact applications.
The products from BASF’s Ultraform (POM), Ultradur (PBT), and Ultramid (PA) lines that have received approval for drinking water applications now also feature ‘Aqua’ trade mark designation in their names, for instance, Ultraform N2320 FC Aqua, Ultradur B4300G6 FC Aqua and Ultramid A3EG10 FC Aqua, respectively.
High-temperature resistant plastics, polyaryl sulfones Ultrason P3010 and Ultrason S3010 complement the portfolio for drinking water contact applications. Besides meeting specifications for drinking water contact applications, these materials have also earned approval for food contact and are manufactured in accordance with good manufacturing practices. Hence, BASF has formed one compact portfolio comprising all of its engineering plastics that have been approved for food and household applications.
A high taste neutrality level, ultra-low migration values, and verification that algae growth will not be accelerated due to prolonged contact with the plastic, are the specifications that must be met by plastics for drinking water contact applications. Aqua portfolio plastics have secured all the approvals in accordance with the standards of WRAS, DVGW and KTW for cold-water applications, and most of them also for hot and warm water.
BASF offers customers with all the required certificates for Great Britain and Germany to get the approval of the final components. If customers need approval from the American National Sanitation Foundation, the ACS and other institutes, the company will help by disclosing the formulation to the respective institutes. In addition, the company is capable of conducting flow tests for customers’ components made with the new suite of plastics at its own flow laboratory, followed by tests for burst pressure or other customer-specific tests.
