Molecular formula :
CAS :
nature : tearing thin edge of the sample. It is the determination of thin films or tear resistance of a test method (Elmendorf France), a definition of terms. The method is to cut the gap provides a sample in a special machine for a tear test units for N. General film materials, often vertical and horizontal different performance and, therefore, we were kind of system. There is a tear-shaped trousers, which is to be split with the long rectangular samples of the two films "trouser legs" Rally withstand the tensile testing machine, completely torn measured samples of the most vigorously, divided by the thickness of the sample to kN / m sample units of the tear strength . The leather industry, divided into incision tear strength and tear strength suture. The former is the gap has been torn at the edge of the Department cracked when he was torn apart by the force required; The latter refers to the leather seam strength, in recognition of the shoes worn at the seams at the firm level. Both leather samples were torn at by the biggest load said. If, chrome yellow leather shoe upper leather is the tear strength of �70N/mm. The rubber industry in the sample parallel to the main axis direction, tearing test unit for the most vigorously divided by the thickness of the test piece, flat kN / m. It is the rubber available an important physical properties. The current test methods many tears, whether cut mouth and I cut two, the specimen shape of the different, pants-shaped, rectangular-shaped crescent and several other corresponding there were pants-shaped tear strength, without cutting rectangular mouth tear strength, cutting rectangular mouth tear strength and slashing mouth crescent tear strength. Tear strength by the specimen shape, thickness, rolling direction (texture), depth of cut, measured temperature and velocity of tears.
