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.
