NATURAL FIBER BASED PRE-PRG™

The ecological and gentle purging compound

Purging compounds

A purging compound is a resin-based material designed to clean machines from contaminants after the manufacturing process.

The purging effect needs to be efficient, it may not harm machinery, and the downtime must be as short as possible for the manufacturer.

Purging compounds are used for cleaning barrels, screws, nozzles, and extrusion dies.

PRE-PRG™ is a highly efficient, ecological, and gentle polymer purging compound primarily composed of renewable and recycled raw materials. PRE-PRG™ does not contain any chemical cleaning additives.

PRE-PRG™ was initially developed for cleaning the most demanding carbon black and graphite compounds and powder coating machinery. Our natural fiber based purging compound is suitable for cleaning thermoplastic and thermoset processing machinery, and it is also ideal for polymer and color changes in everyday use.

As a leading expert in polymer modification and with a desire to test different natural ingredients, our team created a new purging compound for markets.

Sustainable

Made from more sustainable materials and less volume needed for the same results​:​

  • Reduces the CO2 footprint
  • Can be recycled or disposed of in energy waste. Over 50% of ingredients are bio-based or recycled.
economic

Economic choice

Our pilots indicate a reduction of 40% to 70% in the needed volume vs. pure polymer. The total material cost with PRE-PRG™ is lower than with special purging compounds:

  •  Downtime savings​
  •  Material usage of purging compound (kg)​
  •  Cost of purging compound (€/kg)

”The new PRE-PRG® purging compound has sped up the purging of our equipment and improved the quality of purging. The new natural fiber based compound can be used in smaller quantities, and the new product has also allowed us to reduce the amount of waste.”
