Cutting Polyurethane Parts

Cutting Polyurethane Parts​ One of the best machines for cutting urethane parts is a band saw. Long blades of 125 to 175 inches (3,175 to 4,445 mm) are desirable because they stay cooler and keep the urethane from melting. A band type we have found to work well is a 4...

Machining Cast Polyurethanes

Machining Cast Polyurethanes Cast polyurethanes can be readily turned, waterjet cut, sawed, drilled, ground or milled. We offer many engineering shapes of our compounds which can often be used to make prototypes or limited production quantities. It is important to...

Urethane Compound Specifications

Urethane Compound Specifications ​A successfully performing elastomer should be well documented by a meaningful specification. Why? Because hardness alone is not a reliable specification. At the same hardness we produce many compounds with widely different performance...

Polyurethane Stoichiometry

Polyurethane Stoichiometry Urethane Stoichiometry is the chemical relationship of the amount of reactive elastomer polymer to the amount of curing agent used. Selection of proper stoichiometry is our responsibility, it plays an all-important part in compression set...
