Oil and Chemical Resistance of Polyurethanes

Oil and Chemical Resistance of Polyurethanes Need to know which Urethane has the best oil or chemical resistance for your application? Here is a partial list of oil and chemical media to which Gallagher Corporation polyurethanes have been subjected. This data was...

Urethane Shear

Elastomers in shear are generally used in mounting and suspension applications. Urethane elastomers deflect more easily in shear than in compression. Deflection of a urethane system in shear is a function of three things: the shear stress, the shear modulus – G – of...

Urethane Fatigue Considerations

Urethane Fatigue Considerations Fatigue is an important consideration in the design of parts for cyclic dynamic applications. Fatigue and cut growth resulting from cyclic stress-strain are related. When testing for fatigue resistance for a specific application, it’s...

Polyurethane’s Load-Bearing Capacity

Polyurethanes have an unusually high load-bearing capacity, and exhibit deflection and recovery capabilities that far exceed plastics or metals. Internally, polyurethanes have an elastic component that stores and returns energy, and a viscous component that captures...

Polyurethane vs. Metal, Plastic and Rubber

Polyurethane vs. Metal, Plastic and Rubber Compare Polyurethanes to The Performance of Metals, Plastics and Conventional Rubber Polyurethanes have many advantages over metals, plastics, and conventional rubbers: vs. Metal vs. Plastics vs. Rubber Lightweight High...

Introduction to Polyurethane Elastomers

Introduction to Polyurethane Elastomers   What Are Polyurethane Elastomers? Polyurethane elastomers (urethane elastomers) are one type of a large family of elastic polymers called rubber. There are 14 types of rubber in general use. All of these polyurethane...
