Compounded Resins

Compounded Resins are quite common in our industry. Sometimes the additive has processing characteristics so similar to the basic resin that you can dry and process in exactly the same manner as is indicated for the main ingredient.

However, you should consult with the additive supplier to make sure of its drying needs (drying temperature, final moisture content, etc.) as well as its storage, handling and processing needs.  You should not make presumptions about drying temperature, because that could lead to earlier softening in the drying hopper or premature gassing not present in the base resin alone.  You should consult with the supplier of any additive on all matters regarding the new material prior to receipt, storage, handling, drying and processing.
