Screw Clean cylinder purging compounds. Screw Clean 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. Screw Clean purges all thermo­plastics gently, very effective and above all reduces costs. It's quick and easy to apply, easy to use and absolutely non-toxic.

The rub-off effect. Screw Clean purges all commercially available thermoplastics, including the 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! Screw Clean will also give you a clear cost advantage:

1. Shorter machine downtimes
2. Less material expenses
3. Minimizes waste disposal costs
4. Effective personnel placement
5. Ideal value for money

The right type for you... Screw Clean fits to any machine size and is available in three different types: Type SK for small machines, type SM for medium-sized machines, and type N for large machines. Also available as special type Screw Clean S400 for extremely low or high temper­atures on all machine sizes. Screw Clean S400 is also food safe and ideal for purging thermo­plastics, which come in contact with food.
