材料简述：
Description:
SLL218 is a Linear Low Density Polyethylene, copolymer of butene-1. Developed for cast film extrusion. Films obtained with this product show a good processing performance balanced with good optical and mechanical properties as well as processability. Very low gel amount. It contains antioxidant additives.
The minimum biobased content of this grade is 87%, determined according to ASTM D6866.
Applications:
Stretch films; liners; LDPE and HDPE blends and packages for general use.
Process:
Recommended processing conditions for film extrusion about 170 - 210 °C. The optimum processing conditions will vary according to the type of equipment used and cannot be considered as performance guarantee.
