General purpose meets highest performance
U grade’s styrenic-based cleaning power is the strongest purging material of the universal grades. This makes U grade ideal for applications that require higher cleaning power while maintaining low residue.
Great for colour changes that are more demanding
Because U grade is such a powerful purger, it is especially suited for handling more demanding colour changes like green to yellow or black to white.
U grade purging compound is also recommended for hot runner cleaning, as well as sealing and shutting down machines to prevent carbon on start-ups.
