Borstar® FB1350 is a linear medium density polyethylene grade combining excellent extrusion properties with high film stiffness.

Borstar® FB1350 is well suited for mono- and coextrusion of films produced with high neck or low neck extrusion.

Processing techniques

Borstar® FB1350 is easily processed on conventional extruders. Borstar® FB1350 is best processed on conventional LDPE/HDPE or combination extruders. FB1350 is especially developed for high strength, high

stiffness Borstar® grade. Conventional HDPE/LDPE die gaps 1,2-1,5 mm is recommended and this will give the best balance between extruder melt

pressure and physical film properties. Recommended melt temperature range is from 190℃C to 210℃C. Due to differences in screw and die head designs, the optimum temperature adjustments are individual and should be sought for each production line. With suitable equipment Borstar® FB1350 can be drawn down to 15 micron as mono film.

Packaging and storage

Borstar® FB1350 should be stored in dry conditions at temperatures below 50℃C and protected from UV-light. Improper storage can initiate degradation, which can result in odour generation and colour changes and can have negative effects on the physical properties of this product.
