Real-time x-ray diffraction: crystalline orientation during blown film extrusion
Measurements have confirmed that orientation in the polyethylene bubble takes place well past the frost-line height, even after the blown film diameter is locked into place.Characterization of metallocene polyethylenes for sealing layer applications
Molecular weight, molecular weight distribution, chain branching, and melting behavior of metallocene polyethylenes play a crucial role in the sealability and hot tack properties of their films.Stress and dispersive mixing revealed in real time during melt blending
A practical methodology for using dye-filled beads calculates the stress history of a polymer traveling through a twin screw extruder.Polyblend melting in intermeshing counter-rotating twin screw extruders
The screw pull-out technique is used to study polyblend melting in a starve-fed, closely intermeshing extruder.Feed enhancement technology for twin-screw compounding of low-bulk-density material
A novel approach significantly improves the introduction of fine-particle and low-bulk-density materials into a co-rotating twin-screw extruder.Development of novel melt-spun nanocomposite fibers
Melt-spinning can develop new nylon-6-based nanocomposite fibers with promising properties, such as improved tensile modulus.Equal-channel, multiple-angular extrusion of semicrystalline polymers
A new, simple, shear-based approach to solid-phase extrusion could potentially be used to improve the physical and mechanical properties of polymers.Theoretical model sheds light on film blowing
Thin-film equations are formally derived to show how big an effect aerodynamics can have.Modeling intermeshing, counterrotating twin-screw extrusion
Effects of screw-flight thickness, channel depth, and non-Newtonian flow can be predicted and experimentally verified by considering screw-flight shearing.Measuring post-extrusion stretching force in polymer melts
The stretching force of polymer melts depends on the draw ratio and freeze-line position.Viewing 11 to 20 of 39 articles
