ALCUDIA® 1970C is a low density polyethylene grade, produced by high pressure autoclave technology, suitable for extrusion coating. Very high drawdown speeds are achieved throughout the extrusion temperature range, and thin coatings are possible at low temperatures. The molecular structure of the polymer produces an excellent clear coating. It has good heat sealability and moisture barrier properties. Its melt characteristics guarantee good adhesion and low neck-in. There are no smoke or odour problems, even at high temperatures. Contains no additives.

TYPICAL APPLICATIONS

• Extrusion coating.

• Coextruded thin film.

• Injection moulding.

The excellent draw down properties of ALCUDIA® 1970C allow high-speed coatings, up to 850 m/min and 5 g/m² at a maximum extrusion temperature of 330°C.
This material has a very low neck-in throughout a wide range of extrusion conditions.
Recommended melt temperature range for extrusion coating from 275 to 330°C.
Temperature range for coextrusion depending on the processed polymers.
Processing conditions should be optimised for each production line.
