Other Details
Primarily used in packaging industry, our Polythene- HDPE, LLDPE, LDPE, is derived by accurate composition and reaction of various carbons and its compounds. Based on its density and branching, this polythene is processed to form various categories like HDPE, LLDPE, LDPE and others. Extrusion is the most common process used for LDPE (tube, blow and cast films, cables) where as it can also be processed by injection molding or roto-molding.
Extrusion:
Melt temperature : 180-240 C
Higher melt temperatures are needed for extrusion-coating (280-310 C)
A three zone screw with a L/D ratio of around 25 is recommended
Injection molding :
Melt temperature : 160-260 C
Post mold shrinkage lies between 1.5 and 3.5%
