Purges gently, very effectively and cost saving!
purogran® is a purging compound based on thermoplastics and is used for color and material change-overs on all extrusion, injection moulding and blow moulding machines. purogran® purges all thermoplastics gently, very effectively and above all reduces costs. It’s quick and easy to apply, easy to use and absolutely non-toxic.
The rub-off effect.
purogran® purges all commercially available thermoplastics, including technical polymers, and is generally used with the same machine settings as the thermoplastic to be purged. By warming, the material expands, softens up and develops its highly effective rub-off effect: It literally frees the machine — gently and without attachments.
Your advantages:
I use purogran®-type S400 for purging my extruders after high-performance polymer extrusions and achieve excellent purging results with it.
Easy to handle, precisely to measure, clearly visible purging effect!
