The world-leading dairy equipment company milkrite | InterPuls, Methuen Park, United Kingdom is now using Ultrason P 3010 to manufacture housings of milk meter sensors used for checking the milking results of cows, sheep and goats.

 The BASF polyphenylsulfone (PPSU) contributes to the durability of the sensor because of its high toughness and chemical resistance: Thus the milk meters can withstand the rough farm environment as well as the repeated cleaning of the milk meters. The transparent Ultrason grade supports easy visual checking of the milk flowing through the metering device and in the long run does not show any discoloration. It also meets milkrite | InterPuls’s strict requirements regarding food contact approval.

Milk meter sensors are used to control the volume and quality of the milk still within the milking process. The milk can be weighed and its conductivity can be measured. milkrite | InterPuls selected Ultrason® P because farmers can easily see through the transparent material to check the milk’s appearance.

The medium-viscosity grade Ultrason P 3010 also enables a compact and smooth design of the milk meter, ensuring a stable vacuum and foam-free performance. “For other demanding components in dairy technology, like manifolds and buffers, BASF offers further optimized polyarylethersulfones”, says Georg Graessel from Global Business Development Ultrason at BASF.

“The grades Ultrason P 2010, E 2010 and E 3010 meet different demands on toughness and superior chemical performance like resistance against superheated steam needed for repeated cleaning.” When the milk is further processed, all these Ultrason grades can also be used for the production equipment of dairy foods like cheeses, yogurts and curd. These foods contain a high level of butterfat usually causing stress cracking in other materials. Made of Ultrason these components show a high wearability and durability.
