Daploy™  WB130HMS - Borealis A/S - 

Daploy WB130HMS 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 WB130HMS is specially designed for polypropylene foam extrusion, in particular for direct gassing technology. Depending on foam technology, densities of foamed materials in between 40 and 700 g/l can be achieved.

According to the application, Daploy WB130HMS can be used on its own or in blends with other grades of PP with lower melt strength.

Daploy WB130HMS is characterised by:

- Combination of high strength and drawability in melt phase
- High stiffness
- High service temperature
- Foamability in foam extrusion processes, especially by direct gassing
- Thermoformability of foamed materials based on Daploy WB130HMS
- Good insulating properties of foamed materials based on Daploy WB130HMS
- Recyclability

Applications:

- 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
- Thermal and acoustic insulation
