TORLON® Polyamide-imide

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

Metal Detectable Plastics in the Food Industry

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

Plastic Materials Close Up: Polyoxymethylene (POM), Acetal, Delrin®, and Celcon®

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

Rubik’s Cube: How It’s Made and Solution Clues

Emo Rubik, a professor at the University of Budapest in Hungary, designed the now famous Rubik’s Cube in the mid-1970’s. It is made up of 26 smaller cubes and has six faces, each made up of nine different colors: red, yellow, blue, white, green and orange. His intention in designing it was to demonstrate to his students three-dimensional relationships. When he showed the prototype to his students, it was an instant hit not so much as a teaching tool but as a game. … Read more

How to Identify a Plastic Material Using the Burn Test

So you have a plastic part and you need to know what it is made of but you have no idea what plastic it is. This can be a challenging task. Many plastics look and feel alike but we will take a closer look here at some of the ways using a burn test. Please note, this test should be done in an industrial setting and not at home since proper safety protocol must be observed. … Read more
