Cast polyurethane gears offer solutions to problems other materials can not. They are impact, chemical, and abrasion resistant, yielding properties that can not be achieved using rubber or steel. The teeth flex allowing for misalignment yet retain the rigidity to perform and can be designed to sheer, saving more expensive parts of equipment. Other features such as steel hubs manufactured in our machining facility can be molded into the gears to strengthen the polyurethane gear. We can also add friction reducers into our gears to lower the coefficient of friction and reduce the dynamic heat buildup in high R. P. M. Applications. These gears are also sound dampening and can greatly reduce noise due to vibration.
Polyurethane elastomer with excellent abrasion resistance, tear resistance, chemical resistance, corrosion-resistant radio, high strength, high elasticity, high modulus and high elongation.
| 1 |
It is the most versatile, toughest, abrasion resistance elastomer available. It is as soft as Shore A durometer 10 and hard as Shore D scale durometer 85. |
| 2 |
It could be cast into practically any shape, size or complex geometry desired wheels,
gears, O rings, gaskets, tires, roller blades, skate boards etc. |
| 3 |
It can be formulated with high resistance to stresses and it tends to maintain shape and mechanical properties aster fatigue stressing. |
| 4 |
Casting Polyurethane maybe pigmented to resist degradation by elevated atmospheric oxygen and ozone atmospheric concentrations. |
| 5 |
Many cast polyurethane elastomers compounds remain flexible at extreme low temperatures and possess outstanding resistance to thermal shock. Low temperature resistance of polyurethanes make cast parts very practical in extreme arctic conditions. |
| 6 |
Casting polyurethane parts can be made flame resistance by incorporating flame retardants into their formulas. |
| 7 |
Polyurethane can be cast with coefficients of friction varying from very low, for items like bushings, bearings or wear strips, or very high, for items like tries or rollers. |
