...materials that have significantly different melting points and viscosity curves. For example, a material like polycarbonate, which processes around 500 oF, should not be coextruded with PVC, which processes at 300 oF. In that case, the PVC would degrade when it came into contact with the hot polycarbonate...

...gaps or minimal contact areas pose problems for ultrasonic welding processes. When dissimilar plastics are used, differing melting points and potential chemical incompatibility between the two materials must be considered. Ultrasonic welding also requires significant investment for capital equipment...

...and others). * Medical specifications (FDA, USP Class VI, ISO 10993, and biocompatibility). * Sterilization (steam, gamma radiation, etc.). * Impact resistance (structural requirements). * Melting point (to fall within temperature range required for the application without softening or distortion...

...more susceptible to mechanical stress and chemical attack, while exposure to low temperatures generally makes them less ductile. The thermal properties of plastics include the following. Melting Point. The temperature at which a plastic becomes a liquid upon heating or a solid upon cooling...

" components. The binder is then removed using a solvent, heat source, or catalytic reaction and the component heated to from 30 to 100 C below its melting point, depending on the size of the particles. At these temperatures the component sinters, and the resulting molecular movement causes the pore...

melting before the other reaches its melting point, preventing a fusion between the parts. Mechanical fastening, which concentrates loads at fastening points, is not recommended for acrylic parts, as the act of drilling holes or torquing fasteners can introduce potentially damaging stress. Holes...

...the area obtained from a given weight of polymer yield per square meter.2 Amorphous polymers respond better to welding than crystalline polymers do because they soften, melt, and resolidify gradually. However, some amorphous resins with high melting points, such as polycarbonate and polysulfones...

...and with polyethylene, polypropylene, or polystyrene.) Ultrasonics, on the other hand, works like a jackhammer, pounding the plastic from 20,000 to 40,000 times per second, with the resulting friction creating heat and thus melting the plastic. Again, the temperature profile is less desirable than...

...in Figure 1. The matching of extruder screw design to the melting and rheological characteristics of the plastic to be processed is fundamental to extruder performance. Screw design is a complex subject, but most screw elements fall within the ranges presented in the box shown below. The key...
