PCT PURGE™ is a non-corrosive, non-abrasive purging compound that performs by means of mechanical forces released from high viscosity polymers as well as scrubbing minerals and blowing agents. The blowing agents increase the pressure inside the barrel and allow the high viscosity polymers and the scrubbing minerals to reach all the “dead spots” inside the cylinder, the nozzle and the hot runner and therefore releasing all the residual polymers pigments and other contaminants.
Today purging is not anymore only a way to clean and maintain the equipment. It is also a solution for an efficient cost saving as well as a controlled production process.
/ Understand the production and the purging problems
/ Offer customized purging recipes for specific needs and applications
/ Support the staff, from the first tests to regular, routinely usage.
Improve the results and offer new solutions if needed
/ Strive for best results of the purging process as part of an overall
improvement of the production process.
