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
1.Calendering It is suitable for the manufacture of simple sheet and plate products. It is a method of pressing a rubber compound into a certain shape and a certain size by a calender, which is called calender molding. Some rubber products, such as tires, tapes, hoses, etc., must be coated with a th... read more
1. What are the toxic gases produced during the vulcanization of rubber products? The vulcanization process of rubber is semi-closed vulcanization in the oven. Some rubber will emit a trace amount of toxic gas and can smell very heavy rubber. For example, sulfur monoxide, sulfur dioxide, sulfur trio... read more
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
Classification of Rubber gaskets Cell mechanism Closed-cell microporous rubber and open-cell microporous rubber; Foaming rate class Low foaming (visual density ≥0.5g/cm 2 ) and high foaming (visual density <0.5g/cm 2 ); Rubber matrix NR rubber (natural rubber), SBR rubber (styrene-butadiene rubbe... read more
