ALCUDIA® LDPE PE-003

About
ALCUDIA® PE003 is a low density polyethylene grade, produced by high pressure autoclave technology, suitable for blown or cast film applications. It is also used to make little containers by extrusion-blow moulding. This material offers easy processability and good balance of mechanical and optical properties. It does not contain any additives. TYPICAL APPLICATIONS General packaging film and thin shrink film. Lamination to different substrates (paper, aluminium foil, etc), with or without adhesive. T Extrusion-blow moulding of up to 2 litres containers for contact with foodstuffs. Recommended melt temperature range from 150 to 180°C. Processing conditions should be optimised for each production line. ALCUDIA® PE-003 is a low density polyethylene developed for cross-linking by direct addition of organic peroxide or silanes. This grade has the following features: excellent processability, high cross-linking rate and smooth surface finish. This product does not contain additives, so antioxidant must be added. The nature and content of antioxidant ought to be treated carefully because of which should present minimum interference with the cross-linking reaction and ensure thermal stability. TYPICAL APPLICATIONS Insulation of low voltage cables. The ALCUDIA® PE-003 processing conditions depend on the type of cable to be manufactured, kind of equipment used and cross-linking system. The use of filters and a break plate is recommended in order to increase pressure in the cylinder and to avoid contaminations that could decrease the final quality of the cable. ALCUDIA® PE-003 meets the following standards: ISO 1872 PE KN 18D022; ASTM D 1248 I, A3 Grade E5.&&
