Grades documentations

Download Clean VHT documentation

CLEAN VHT is one of the latest innovations coming from Polytechs Laboratory. This grade pushes back the limits of Clean Xpress purging compounds by reaching 300°C as maximum temperature while ensuring the most efficient cleaning efficiency in the market (recognized by industry peers and third parties).

Download Clean HP documentation

CLEAN HP is a purging compound containing high level of additives (non-abrasive minerals and organic additives) and Polyethylene Metallocene as carrier. He is especially useful in extrusion applications.

Download Clean HDPE documentation

CLEAN HDPE is suitable to use in injection moulding of styrenic (co)polymers, PMMA, polyolefin or hard PVC or extrusion of hoses, pipes, cables or profiles based on polyolefin, PVC, styrenic (co)polymers, PMMA or rubberlike resins as well as colour or additives master batch based on polyolefin carrier.

Download Clean HR documentation

CLEAN HR is one of the latest innovations coming from Polytechs Laboratory. This is the second generation of hybrid purging compounds suitable for Hot Runners systems in Injection Molding. Its ability to clean the impurities and contaminants lodged into the small cavities & angles of hot runners without damaging them with its controlled PSD (particle size distribution) makes it the perfect support for your color / material changes and maintenance operations.

Download Clean PP documentation

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.

Download Clean LDPE documentation

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.

Download Clean KDN documentation

CLEAN KDN is one of the latest innovations coming from Polytechs Laboratory. CLEAN KDN is a purging compound containing a high level of additives semi-abrasive minerals and organic additives based on HDPE. The product in granular form opaque, beige, is used to reduce the cleaning time. This product runs smoothly and can itself be easily removed from the extruder. This product do not contain silica or oleamide.
