In pyrolysis, the polymer matrix is oxidized at temperatures >500°C, recovering energy plus the fibers.
It's a collective effort that involves stakeholders at every point of the value chain.

High viscosity is usually associated with high melt strength.
Extrusion, blown film production or blow molding requires high melt strength.

N95 masks, for example, rely on multi-layer construction, with a middle layer made from melt-blown non-woven material.
This masterbatch was necessary for the manufacture of melt-blown non-woven polypropylene used to make the protective face masks with long-lasting filtration properties.
By introducing additives with charge storage properties, “charge traps” were created to capture the electret charge being applied to melt-blown non-woven material.
