Borealis Daploy™ WB130HMS High Melt Strength Polypropylene for Foam Extrusion  (discontinued **)
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Extrusion Grade

Material Notes: Daploy WB130HMS resin is a propylene-based, structurally isomeric polymer, which combines significantly increased melt strength with largely drawability of the polymer melt. Thus, the material is generally characterized by improved processability in polymer forming technologies where stretching flows occur.

Daploy WB130HMS has been developed for thermoformable, foamed films and sheets, lightweight packaging trays, beakers and containers, microwaveable food packaging, technical foams for automotive applications such as headliners, carpet backing, door liners, parcel shelves, water shields, under-the-hood acoustic panels, cushioning and protective packaging, and thermal and acoustic insulation.
