Clean HR

Purge injection molding hot runner

Clean HR


Clean HR is one of the latest innovations coming from Polytechs Laboratory. This is the second generation of hybrid purging compounds suitable for Hot Runners systems in Injection Molding. Its ability to clean the impurities and contaminants lodged into the small cavities & angles of hot runners without damaging them with its controlled PSD (particle size distribution) makes it the perfect support for your color / material changes and maintenance operations. Approved internally and by industry peers – from 2 to 8 shots only to purge & clean challenging color changes.
