Polyolefins

Cavity pressure feedback helps control variation, monitor part quality, and support increasingly autonomous injection molding processes.

Natural pigments can color PLA and PBS, but thermal stability and lightfastness remain key challenges during processing and use.

Automation, virtual DOE, and connected production data are reshaping how engineers optimize injection molding processes.

MFI and capillary rheometry provide useful flow data, but they may not fully predict polymer behavior under injection molding conditions.

In-line Raman spectroscopy and rheology can reveal material changes during extrusion, helping track resin changeovers, viscosity, and process stabilization.

The EU PPWR is now in effect, bringing new rules on recyclability, recycled content, EPR, PFAS, labeling, and packaging efficiency.

Uneven cooling creates internal stresses that cause warpage. Better mold cooling improves dimensional stability and part quality.

Polyolefins dominate healthcare packaging, but low recycling rates reveal a major sustainability gap in medical plastics waste.

Bio-based additives support sustainable plastics, but cost premiums, feedstock volatility, and compliance pressure complicate adoption.

Research into optimizing the pyrolysis of automotive plastic waste demonstrates the potential to produce oils with properties approaching those of commercial diesel.
