Manufacturing:Materials and Processing Polymer A single coating can be based on several polymers varying greatly in composition:polar and nonpolar vinyl polymers, urethanes, epoxies, polyesters, and alkyds. This way, the rheology, wetting properties, reactivity, and chemical resistance of the coatings can be optimized beyond what can be obtained by single polymer systems.

Avoid Those Devilish Angel Hairs Plastics Technology

Aug 23, 2011 · The ideal average velocity when conveying PE or PP is in the range of 4000 ft/min. In a vacuum conveying system the velocity increases as the air expands and moves towards the vacuum source. The result of this air expansion is a terminal velocity that can be around 5000 to 6000 ft/min.
