- 50% faster injection molding changes
- Cleans catastrophic carbon deposits


Industry Tested
Made in USA
Industrial screw and barrel cleaning compounds engineered to eliminate carbon deposits, streamline color changes, and minimize downtime in injection molding, extrusion, and blow molding operations. MD Plastics offers chemical and mechanical purging solutions with proven material efficiency, temperature versatility, and superior cleaning performance for demanding plastics processing applications.


What is the difference between chemical and mechanical purging compounds?
Chemical compounds use surfactants to clean deposits while mechanical compounds physically scrub barrel surfaces. Both effectively remove carbon and enable material changes depending on application requirements.
How much purging compound do I need for a typical color change?
Can these compounds handle heat-sensitive materials like PVC or POM?
What temperature range do your purging compounds cover?
How quickly can I expect to receive purging compounds after ordering?
Do you provide technical support for optimizing purging procedures?
Are your purging compounds compatible with hot runner systems?
