Basic process flow of rubber seals
1. Raw rubber mastication Rubber processing technology has certain requirements for the plasticity of raw rubber. In order to meet various process performance requirements, raw rubber must undergo mastication. However, the initial plasticity of most synthetic rubbers is controlled during the synthesis process, so they can be directly mixed without mastication. In addition, natural rubber, hard nitrile rubber, isoprene rubber, styrene-butadiene rubber, etc. all need moderate mastication. Mastication can reduce the viscosity of rubber, making it easier to mix in compounding agents; mastication can improve the rheological properties of rubber, reduce die swell and calender shrinkage; mastication can also improve the solubility and moldability of rubber. Mastication must be moderate; excessive mastication will reduce the sulfur...
