MOL Group BRALEN+ FB 4-52 LDPE, Film Grade
Categories: Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE); Low Density Polyethylene (LDPE), Film Grade

Material Notes: Description: BRALEN+ FB 4-52 is a film grade of low density polyethylene with low friction, good processability and optical properties. This grade contains erucamide slip agent and antiblocking agent.

Applications: BRALEN+ FB 4-52 is intended for production of thin slip films for automatic packaging and cast films. Recommended film thickness is 0.015 to 0.040 mm.

(1) Density has been measured on pressed mould specimen according to internal method. (2) Film properties tested using 50 µm thick blown film extruded at melt temperature of 170 °C and blow up ratio 2.5:1. (3) Typical properties measured on standard injection molded test specimen according to ISO 294-1.
