Momentive Tufel™ III Silicone Rubber Test Performance Data
Hysteresis
The chart below measures the loss of elastic energy for an elastomer when it is dynamically deformed and allowed to return to its original state. This test comprises an elongating standard ASTM tensile dumbbell to 100% stretch, then returning to the original position. The measure of hysteresis is in percentage, and the chart shows Tufel™ III 92506 and 92656 silicone compounds have lower hysteresis loss than competitive platinum and peroxide-curable silicones when used in tubing applications. When a silicone has lower hysteresis, this can result in less material fatigue over the lifetime of the elastomer in mechanically dynamic applications.
Resilience
The chart below exhibits how Tufel™ III silicone rubbers showcase a higher resiliency than competitive platinum and peroxide-curable silicone elastomer materials.
Compression Set
The chart below showcases Tufel™ III 92506 and 92656 silicone rubber compounds’ reduction in compression set values without requiring a post-cure.
Autoclave Resistance
Tufel™ III 92506 and 92656 silicone rubber compounds highlight the performance over exposure to 1,000 autoclaving cycles and can be considered for medical applications that require repeat sterilization performance.
