3 Top Reasons There is a Shortage of Nylon 6/6

Worldwide Shortage of Nylon 6/6

There is currently a worldwide shortage of nylon 6/6 largely due to shortages of the key precursor adriponitrile or ADN. Nylon 6/6 is used extensively to make automotive parts, as well as cable ties, power tools, nylons, fabric, fasteners and is used in numerous industrial applications. Nylon 6/6 provides the best mix of processability, performance and value for the price.

How Plastics Wear Against Metal

In tests mating thermoplastic composites and AISI 1141 cold-rolled steel counter-faces, the highest composite wear factors (greatest wear) resulted with the smoothest range (8-12 µin.) of metal surface finishes.  This result, contrary to what might be expected intuitively, is attributed to the adhesion-and-deformation friction mechanism of metal/plastic combinations.  The 12 to 16 µin. range yielded the lowest wear factors, and the 50 to 70 µin. surface-finish range generally produced intermediate wear-factors for most composites (un-reinforced formulations were exceptions). … Read more

History of the Screw

No one knows when the first screw was created but it is believed that by the first century it was used in a screw press. However, screw presses were known in Roman times to squeeze olives for oil and grapes for wine.  Archytas of Tarrentum is credited by the Greeks with the invention of the first screw.  However, Archimedes the Greek philosopher  is also credited with inventing the screw around 234 BC. The Archimedes screw was used in a water pump that employs a rotating helical chamber to cause water to move uphill. … Read more
