| ALCUDIA® 5502-E natural compound is an hexene copolymer of medium molecular weight apt for the extrusion of corrugated pipes for protection of cables, one or multilayered pipe. This product is supplied in natural colour but it can be easily coloured with pigments steady at processing temperature, using dry-colouring or masterbatch techniques ALCUDIA® 5502E is a high-density polyethylene copolymer of hexene, with high molecular weight. It is specially designed to make, by blow molding-extrusion, tanks for liquid detergents and chemicals. This grade contains stabilizers according to the end use of the item in order to reinforce the thermal stability. Good environmental stress cracking resistance can be obtained with ALCUDIA® 5502E due to its molecular weight and density. TYPICAL APPLICATIONS Packaging of non-aggressive liquid detergents and chemicals. Recommended melt temperature range from 180 to 200°C. Processing conditions should be optimised for each production line.&& |
