The screw is one of the six classical simple machines.1 It is a mechanism that changes rotational motion to linear motion and rotational force or torque to a linear force. If looked at geometrically, a screw can be regarded as a narrow incline plane wrapped around a cylinder. The screw is one of the most common simple machines and consists of a cylindrical shaft with helical grooves or ridges around the outside called threads. … Read more

TORLON® is the Solvay brand name for polyamide-imide or PAI. Polyamide-imides demonstrate exceptional mechanical, thermal and chemical resistance properties making them well suited to severe environmental service. PAIs have exceptionally high heat performance with a continuous service temperature of 260°C or 500°F and are inherently flame resistant. They are known to have the highest strength and stiffness at higher temperatures of any thermoplastic. Torlon resists wear, creep and is also extremely durable from cryogenic temperatures to 275°C (535°F). … Read more
You are eating a hot dog or digging into a carton of your favorite ice cream. You don’t even think there could be a piece of plastic or metal or just small particles of these materials in there- broken or worn off from the machinery and tools used to get your favorite foods to your grocers’ shelves. But many of the food processing machines and tools used to provide food products have plastic parts in them or are made of plastics. … Read more
Polyoxymethylene (POM) is a thermoplastic materialalso known as acetal. It is a molecule containing the functional group of carbon bonded to two –OR groups. POM was first discovered by German chemist Hermann Staudinger who won the 1953 Nobel Prize in Chemistry. He had studied it in the 1920s but found it to be thermally unstable. DuPont synthesized a version and filed for patent protection of the homopolymer crediting R.N. MacDonald as the inventor. … Read more
