What is the relationship between the hardness and tensile strength of rubber pad?
The molecular weight increases, increasing the fan Edward force, the chain segment is not easy to slip, the equivalent of molecules formed between physical crosslinking points with the molecular weight increased, the tensile strength increased to a certain extent reached equilibrium; the microstructure of the molecule, such as the effect of CIS and trans type structure; crystallization and orientation.
The main factors affecting the tensile strength of rubber are: the main valence bond, intermolecular force and polymer chain flexibility of macromolecular chains. The relationship between tensile strength and structure of rubber: the intermolecular forces are large, such as polarity and rigid groups;
Tensile strength is the ultimate ability to characterize a product against tensile failure.
The relationship between the hardness and tensile strength of rubber pad: the higher the hardness, the greater the tensile strength.
