Durables

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.

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

Temperature, screw speed, and feed rate can shift polycarbonate color by changing melt viscosity, shear, and pigment dispersion.

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

Mechanical recycling can change the color response, surface quality, and mechanical performance of thermochromic polypropylene used in smart packaging.

Real-time resin diagnostics help processors monitor melt behavior, manage recycled-content variability, and improve plastics quality control.

LEGO is reducing emissions and expanding the use of renewable, recycled, and mass-balance plastics across its global toy portfolio and supply chain.

Carbon black pigments limit NIR sorting, raising recyclability, compliance, and cost challenges for black plastic packaging.

Smart controls and modified plasticizing systems help stabilize recyclate injection molding despite variations in viscosity and feedstock.
