Explanation

It is called constant tensile stress. When the rubber sample is stretched to the specified elongation (usually 100%, 300% and 500%) on the tensile testing machine, the ratio of tensile force to the cross-sectional area of the sample before stretching, in MPa. The larger the molecule a of rubber, the higher the curing degree, and the greater the intermolecular force, the greater the tensile strength. Some rubber and plastic products require both a certain elongation and strength in practical applications, so the measurement of constant elongation strength is of great significance.
