Solid State Polymerization (SSP)
In 2010 Cumapol started up the SSP lines as toll converter.
Most applications require a high IV polyester in order to increase the end-product’s strength. The regranulated or compounded granulates can be upgraded to an IV of maximum 1.5. For batches Of >100MT we make use of our continuous line which is working under nitrogen. Smaller batches can be processed on our vacuum tumble dryer production line.
Highest purification level
Our SSP-technology turns out to provide the highest purification level of the industry. In combination with our regranulation process we can offer 100% approved food contact materials according the EFSA-regulations (recy085).
