We take pride in designing the best possible polyurethanes the industry has to offer, and that is due to the strict guidelines and standards we set for our self.
Sharp edges or corners, externally or within the polyurethane part, should be avoided, particularly where the polyurethane is stressed.

Millable urethane rubber is available in hardnesses ranging from approximately 30A-90A. While castable urethanes cover this range, they also can be formulated slightly lower and significantly higher. In the range of 30A-70A, millable urethane rubber has superior physical properties to castable urethane, primarily tensile and abrasion resistance. At these lower hardnesses, millable urethane takes advantage of reinforcing fillers to build strength while castable urethanes often need to be plasticized to reach durometer readings below 55A. Once the hardness gets above 70A, and up to 75D, the tensile values of castable urethane start to catch up and surpass millable urethane. This can also translate into increased load bearing properties and superior abrasion resistance with castable urethane. Continue reading
