1、The larger the molecular weight, the larger the constant tensile stress.
2、With narrow molecular weight distribution, the constant tensile stress and hardness decrease.
3、The intermolecular force is large, the constant tensile stress is high.
4、The constant elongation stress and hardness increase with the increase of cross-linking density. The traditional vulcanisation system can obtain high elongation stress and hardness.
5, the elongation stress and hardness increases with the decrease of filler particle size, with the increase of structure degree and surface activity, with the increase of filler dosage.
6, the fixed elongation stress and hardness with the increase in the amount of softener and reduce.
7, rubber-plastic blending can improve the constant elongation stress and hardness, such as NR/PE, HS blending, NBR/PVC blending, EPDM/PP blending.
