Daploy WB120HMS Borealis Polypropylene, High Melt Strength

Product Description

Daploy WB120HMS resin is a propylene-based, structurally isomeric polymer, which combines significantly increased melt strength with largely improved drawability of the polymer melt. Thus, the material is generally characterised by improved processability in polymer forming technologies where stretching flows occur.

Daploy WB120HMS is specially designed for polypropylene extrusion, in particular for the conventional blown film process with air cooling, where an improved bubble stability, smooth running and higher output rate can be achieved.

Daploy WB120HMS should be used preferably in blends with standard PP with lower melt strength. The recommended concentration of Daploy WB120HMS to standard PP is 10-20%.

Daploy WB120HMS is characterised by:

A combination of high strength and drawability in melt phase

High stiffness

High service temperature

High draw-down in blown film process with air cooling

Balanced shrinkage

Recyclability
