DucaFreeze: a calcium organic rigid PVC based compound eliminates the need to strip dies for cleaning
Using new generation stabiliser technology we have created a freeze compound with elevated temperature resistance that makes it suitable for use as a freeze or purge compound in rigid and flexible PVC materials across a wide range of applications.
It is easy to use and is so efficient that tooling does not have to be stripped down for cleaning.
Conventional non-lead purge and freeze compounds have thermal stability limitations which render them unsuitable for use in high end rigid PVC applications where processing temperatures can exceed 200°C.
Ducafreeze can be used to purge material in the die while processing plant temperatures are being reduced. It can be left in the tooling and machine for extended periods. On start up the temperature is increased allowing Ducafreeze to be purged through using standard material – saving both time and resources as the die does not need to be stripped down and cleaned. This has the knock-on benefit of reducing wear and the risk of damage to tooling caused by continuous disassembly, cleaning and reassembly.
Alternatively Ducafreeze can be used as a conventional purge material that when cooled is easily removed from metal surfaces and intricate die flow paths – again minimising the
