EF2222 is a low-density polyethylene (LDPE), with excellent processability and low gel content. Those features allow production of thin and highly uniform films.
Additives: No additives
Application: Smooth or embossed films for diapers, disposable sheets, etc. Films for lamination. Injection-Blow Molding. Foamed applications.
Process: Recommended processing conditions for film extrusion about 145 - 190 °C. The optimum processing conditions will vary according to the type of equipment used and cannot be considered as performance guarantee.
