Are specialized purging compounds important to use?

The use of a specialized purging compound can be tremendously helpful in reducing the amount of time and material required to clean a machine from color and polymer contamination or material degradation. They are the best solution for transitioning between incompatible polymers and polymers with a wide processing temperature difference. They can also solve contamination issues when the polymer is transparent, and when changing colors — especially when hot runner molds are used in injection molding facilities. The use of specialized purging compounds results in saved time and money.
