• Rubber vulcanization

    The process of converting plastic rubber into elastic rubber is called vulcanization. It is to add a certain amount of vulcanizing agent such as sulfur, vulcanization accelerator, etc. to a semi-finished product made of raw rubber, and heat and heat the temperature at a predetermined temperature in ... read more

  • Rubber gasket mastication

    Raw rubber is elastic and lacks the plasticity properties necessary for processing, so it is not easy to process. In order to improve the plasticity, the raw rubber is masticated, so that the compounding agent is easily dispersed uniformly in the raw rubber during the kneading, and also helps to imp... read more

  • Structural composition of rubber gasket

    Linear structure: the general structure of unvulcanized Rubber gasket. Due to the large molecular weight, it has a thin mass after no external force. When the external force acts, the exclusion force is removed, the entanglement degree of the thin group changes, the molecular chain rebounds, and a s... read more
