Clean HP

About

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

About

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

Processing temperatures

From 100°C to 200°C.

Compatible resins
