Extrusion Process

The process of blending plastics with other ingredients to create new polymers is known in the industry as "compounding".
The compounding process allows polymer chemist the opportunity to improve the qualities of standard plastics. These new plastics can be stronger, more flexible, or more resistant to the elements than their original components, depending on the needs of the project.

At General Polymer Services, our team of experts will apply their knowledge of compounding to develop the materials you need for your next project.


The compounding process involves blending specific polymers and additives in a liquefied state. These polymers can include PP, PE, TPE, and many others. The additives can bring the desired qualities to the finished products.

The compounding action itself can include heating the ingredients to help them blend, mechanical actions that bring the desired components together, or use chemical interactions between the ingredients to aid the process.
