Urethane Elastomer Product Line


Polaris Polymers develops and manufacturers room temperature and hot cast processing and curing polyurethane elastomers for demanding applications.

Polyurethane elastomers are unique design and construction materials combining many of the advantages of plastics, metals, and ceramics with the extensibility of rubber. Depending upon the type and performance requirement, they are cast and cured at room temperature or processed and cured at elevated temperatures. High performance systems begin as prepolymers in order to maximize physical properties, reduce toxicity, control reaction rates and improve processing characteristics. They are combined with curatives and are molded into shapes that are used in industrial and mechanical parts, graphic arts, mining, oil and gas, recreation and sport, and solid industrial tires and wheel industries.


Cast elastomers or urethane parts can provide a wide range of properties to include:
