Three of the most useful plastics for making bearings are Acetal, Delrin AF® and PTFE. Acetal and Delrin AF® are both thermoplastics; meaning that these materials can be heated into a liquid form and then cooled into a solid retaining the shape of either the extrusion nozzle or the mold used to shape it. PTFE has the lowest friction constant of any plastic material. It is not a thermoplastic but it can be extruded. … Read more
Thermoplastic polyurethane* is a fully thermoplastic elastomer. It is elastic and melt-processable. TPU can be extruded, injection molded, and compression molded. Because TPU is a linear segmented block copolymer made up of hard and soft segments, it allows for a considerable number of physical property combinations. This diversity makes TPU an extremely flexible material, adaptable to dozens of uses. For even greater utility, the molecular weight, ratio, and chemical type of the hard and soft segments can be varied. … Read more
There are literally hundreds of screw drives. In this article, we will take a look at a few of the most popular kinds. A screw drive is part of the design of a screw that allows it to be turned into place using a mating tool like a screwdriver or Allen wrench. Most screw heads come in a range of styles, including a Phillips fillister head or a slotted flat head, as well as in various sizes. … Read more

Biodegradable plastics have become more appealing in recent years as traditional consumer plastic products continue to choke landfills, negatively impacting the surrounding environment. Biodegradable plastics take between three and six months to decompose, which is a significant improvement over the hundreds of years most traditional plastics need. Biodegradable plastics are still in development and the current commercially available grades are far from perfect. Despite any drawbacks, scientists continue to develop and refine bioplastics because the potential benefits are hard to deny. … Read more
