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

Polyurethane suppliers and processors are continually looking to develop new materials and applications to take advantage of the unique properties of urethane. One advantage that urethane has over rubber is much higher abrasion resistance. This has historically been particularly true as the hardness reaches Shore 80A and above. Although materials of softer hardness have long been available, the physical properties and abrasion resistance has not been a good as rubber in the 50A-70A range. New developments are allowing for both polyether and polyester based materials that are great improvements over currently available urethanes and even better than natural rubber and SBR. Typical applications for these types of materials would be in systems with heavy flow of particulate containing liquids or slurries. Continue reading

At the end of April, I was elected to serve as an Officer on the Board of Directors of the Polyurethane Manufacturers Association.
The PMA is a wonderful, global, collaborative organization comprised of over 150 companies who are urethane processors, suppliers, and others all working together to share best practices and drive polyurethane industry growth in diverse markets. PMA members share the latest industry research and knowledge, and work together to promote polyurethane’s many advantages over other materials like rubber, plastic, and metal. Continue reading
