Resilience: also known as resilience, or impact elasticity, elasticity, is also an important performance indicator to measure rubber elasticity. With the pendulum at a certain height of impact rubber, the ratio of the height of the rebound and the original height is called the rebound rate, expressed as a percentage (%), the greater the value, the higher the elasticity of rubber.
Tear permanent deformation: referred to as permanent deformation, is also an important indicator to measure rubber elasticity. After the rubber is stretched and broken, it is parked for a certain time (usually 3 minutes), and the ratio of the increased length of the deformation part to the original length is expressed as a percentage (%). The smaller the straight, the better the elasticity of the rubber. In addition, the elasticity of rubber can also be measured by compression permanent deformation.
Fixed elongation strength: also known as fixed elongation strength. It refers to the force required per unit area when the rubber is extended to a certain length, that is, when it is extended to 100%, 200%, 300%, 500%. In terms of N/cm2. This is an important mechanical index to measure the strength and toughness of rubber, the greater the value, the better the tolerance of rubber, indicating that this rubber is not easy to produce elastic deformation.
