HDPE is suitable for various processes of thermoplastic molding, such as injection, extrusion, blow-molding, etc. Requirement and condition set are different for each process, but they share common problems in colour switch and black spot contamination.

Since the finish product are varied, different color, different shape, different diameter, there is always a problem of color switch, and in some circumstances, during the processing of HDPE, it is very easy to generate impurities similar to carbon spots, yellowish residues, etc. These impurities goes into finish products, which leads to increased scrap rate. What to do with impurities in HDPE extrusion process?

After in-depth research of HDPE, SANP Tech. has launched a special PE screw cleaning agent which can effectively prevent the generation of these impurities and clean residue color contamination. The material doesn’t contain abrasives and is environmentally friendly.
