Engineering resins for water applications
German firm BASF says its Ultramid PA, Ultradur PBT and Ultraform POM are now approved for applications that come into contact with drinking water.
To be marketed under the Aqua brand, the portfolio in the drinking water realm is complemented by the firmís high-temperature resistant polyaryl sulfones Ultrason P3010 and Ultrason S3010. In addition to complying with the regulations for contact with drinking water, these plastics are also approved for food contact (FC) and are produced according to good manufacturing practices (GMP).
The special requirements made of plastics that come into contact with drinking water include very low migration values, a high level of taste neutrality and confirmation that long-term contact with the plastic will not cause accelerated algae growth.
