Plastic Compounding
Plastic compounding, reprocessing, re pelletizing all mean the same or at least a very similar process which is defined as :
Compounding Plastics
The incorporation of additional ingredients needed for processing in order to have optimal properties. These ingredients may include Additives to improve a polymer's physical properties, stability or process ability. Compounding is usually required for recycled materials for the following reasons:
In our process we as recyclers use specialized equipment designed especially to process Recyclable material and to deal with and remove issues that frequently occur in recycled material the main one being moisture content followed by contamination with wood metal or other contaminates and then homogenising the polymer thoroughly to mix the varying grades of polymer that can be present in a recycled plastic mix. Our equipment removes these issues by vacuum, filtering and mixing among other specific technology.

- Recycled materials are typically ground from parts that produce flakes. The compounding (palletizing) process turns them into pellets that can be more easily handled by traditional plastics processing equipment.
- It allows Additives to be compounded into the recycled material to meet target application requirements.
- It allows virgin materials to be mixed with recycled materials to meet material specifications for performance and recycled material content targets.
- It provides a very important homogenization step. Recycled materials are usually a mix of many different grades of the same basic material. Even though the materials might be from the same family, differences in molecular weight, copolymer ratios, etc. can lead to a mixed material having poor homogeneity. The intensive physical mixing in a molten polymer that is achieved during extrusion can homogenize different grades of materials and even some types and amounts of foreign material that might not have been removed during the recycling process.

As well as the equipment its self knowing the correct way to process the plastic is also vitally important, and how to not degrade it, and to get the most uniform end polymer by carefully blending the materials. As you would expect we have this specific knowledge and are willing and able to process you material for your re-use should you require it.
We carry out his compounding work on Toll or Service work basis for a range of customers see our toll work page for further details of our process and capabilities and ring us for any further information you may need
On completion of this process a clean uniform plastic pellet is produced, that in turn is packaged in to IBC sacks or octi bins for shipment.
