Precision Molding
Polyurethanes (”Urethanes”) are a very versatile elastomer that can be manipulated through chemistry, allowing it to take on a multitude of unique qualities. Polyurethane compounds possess an extraordinary combination of physical, mechanical, and environmental properties. Urethanes bridge the gap between plastics and rubber. The resins can be highly customized to suit your specific needs, particularly the ‘hardness’ or durometer of the material as well as the color.
Did you know you can replace acetal and nylon with urethane in most applications?
Some advantages to using Polyurethane are:
• Excellent resilience
• Extra toughness and durability
• Very high load bearing and cut resistance
• Low compression set
• Very good impact resistance
• Excellent abrasion resistance
• Ability to customize hardness & color
