An IV monitoring system has been developed to compliment the HVTSE (High Vacuum Twin Screw Extrusion) system being offered for "dryer-less" production of PET sheet. The HVTSE system developed by Luigi Bandera is offered exclusively in North America by Processing Technologies International (Aurora IL) as part of a strategic business alliance between the companies. To date, Bandera has installed more than 80 of these "dryer-less" systems world-wide.
The unique technology represented in PTi's real-time IV Monitoring System is based on precise measurement of melt temperature and capillary piping pressures such that the viscosity and subsequent IV can be accurately calculated. These results are benchmarked against the ASTM D4603 Solution Test Method for measuring IV and possess an accuracy of +/- 0.02 dl/g. The extracted test data is continuously fed into PTi's flagship TITAN control system, where it can be displayed, stored and readily accessed.
The ability to monitor and track the relative level of the material IV in-process and in real-time is an invaluable process tool. Identifying any deviation in the processing conditions and being able to take corrective action to address those conditions is critical to maintaining consistent and efficient production.
PTi will be installing a 2,500-lb./hr dryer-less twin screw extrusion sheet system to demonstrate processing PET and PLA along with other polymers during Q1 of 2011. This system will include the IV Monitoring System to provide customers with a hands-on opportunity to evaluate system capabilities.-[email protected]
