Why use a PTFE (Polytetrafluoroethylene) instead of Rubber in a Rotary Shaft Seal?

PTFE Rotary Shaft Seals Outperform Rubber Shaft Seals

Elastomeric seals performed well for many years, but as the applications and environments became more demanding, elastomers had a hard time keeping up.  If the application pressure is above 30 psi or the operating temperature goes above 275°F, elastomers simply don’t perform as well as, say, PTFE. (polytetrafluoroethylene).  In this article, we are going to look at 3 areas where PTFE rotary shaft seals outperform rubber shaft seals.

Engineer’s Choice for Low-cost High-volume Polymer Bushings?

High-Volume Low-Cost Plastic Bushings

In this article, we are going to discuss what the best choices are for high-volume low-cost plastic plastic-bushings-cost-effective-Advanced-EMC.pngbushings.  When an engineer is designing a part to be manufactured, there are two approaches: 

  1. the first is to choose an appropriate material, then select a manufacturing process compatible with the material;
  2. the second is to select a manufacturing process, then choose an appropriate material from the ones that are compatible with that process. 

Let’s try answering the question for today’s article by starting with manufacturing processes for plastics.
