Mechanical Recycling of Thermoplastics: A Review of Key Issues

Waste, 2023
During the last decade, the consumption of plastics has increased highly in parallel with plastic waste. The transition towards a circular economy is the only way to prevent the environment from landfilling and incineration.

Influence of mold temperature and annealing on the microstructure and mechanical properties of ESO-plasticized PP/CL composites [PDF]

Polyolefins Journal
Composites of polypropylene (PP) and calcium lactate (CL) with a constant weight percentage of 60% and 40%, respectively, were compounded with 3, 5 and 7 phr of epoxidized soybean oil (ESO) plasticizer using an internal mixer.

Potential of Incorporation of Antimicrobial Plant Phenolics Into Polyolefin-Based Food Contact Materials to Produce Active Packaging by Melt-Blending: Proof of Concept With Isobutyl-4-Hydroxybenzoate

Frontiers in Chemistry, 2019
There is an increasing interest for active food packaging incorporated with natural antimicrobial agents rather than synthetic preservatives. However, most of plastics for direct contact with food are made of polyolefins, usually processed by extrusion ...

Prodegradant Additives Effect onto Comercial Polyolefins

, 2019
Prodegradant additives (PDA) came up in the last few decades as a possible solution to the low degradability of polyolefins. PDAs attack polyolefins chains cutting and degrading them to a degree that eventually may allow phagocytosis by microorganisms ...

Functionalized Polyolefin With Photoresponsive Surface

ChemistryEurope
The introduction of stimulus‐responsive groups can give polymers some material properties that cannot be realized simply by design and synthesis. Polyolefins, due to their nonpolar nature, suffer from poor compatibility with polar materials; however ...
