Clean HP®

Clean HP is a purging compound containing high level of additives (non-abrasive minerals and organic additives) and Polyethylene Metallocene as carrier*.
Is especially useful in extrusion applications.
Is significantly reduces the cleaning time of the screw of the extruder. Is runs smoothly and can itself be easily removed from the extruder.

Processing temperatures

From 80°C to 230°C.

Clean LDPE®

Clean LDPE is a purging compound containing high level of additives (non abrasive minerals and organic additives) and Low Density Polyethylene (LDPE) as carrier*.
He is especially useful in extrusion applications.
He significantly reduces the cleaning time of the screw of the extruder. He runs smoothly and can itself be easily removed from the extruder.

Processing temperatures

From 100°C to 200°C.

Clean PP®

Clean PP is a purging compound containing high level of additives (non abrasive minerals and organic additives) and polypropylene (PP) homopolymer as carrier*.
He is especially useful in extrusion of profiles as well as in injection moulding.
He significantly reduces the cleaning time of the screw of the extruder or the barrel of the injection moulding machine. He runs smoothly and can itself be easily removed from the extruder or moulding machine.

Processing temperatures

From 180°C to 230°C.

Clean HDPE®

Clean HDPE is a purging compound containing high level of additives (non abrasive minerals and organic additives) and High Density Polyethylene (HDPE) as carrier*.
He is especially useful in extrusion of profiles as well as in injection moulding.
