purogran® cylinder purging compounds.
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.
Cut costs! purogran® will also give you a clear
- Shorter machine downtimes
- Less material expenses
- Minimizes waste disposal costs
- Effective personnel placement
- Ideal value for money
The right type for you... purogran® fits to any
machine size and is available in three different types: Type K3 for small machines,
type K5 for medium-sized machines, and type K8 for large machines. Also available as
special type purogran® S400 for extremely low or high temperatures on all machine
sizes. purogran® S400 is also food safe and ideal for purging thermoplastics coming in contact with food.
Try us. See for yourself and run a practical test — samples of all
types can be obtained free of charge without obligations.
