The Capabilities of Custom Urethane

The Capabilities of Custom Urethane
Urethane's unique physical properties allow it to be molded into thousands of custom parts. Because of it's abrasion resistance, high load capability, and superior dynamic properties, Urethane is the perfect material for creating custom parts. When creating sometimes intricately designed custom shapes, urethane will begin as a rod, tube, sheet or bar. This shape is...

Why Does Colour Vary in Natural Polyurethanes?

Why Does Colour Vary in Natural Polyurethanes?

Natural polyurethanes vary from a light tan (almost yellow) to a medium-dark amber (almost greenish). This variation is noticed from supplier to supplier, and even within a given supplier’s production. Black or other colored (pigmented) polyurethanes do not typically exhibit this variability in color. It is important to note that these color variations...
