Liquid silicone rubber is relative to solid high temperature vulcanized silicone rubber, which is a liquid rubber, with good fluidity, fast vulcanization, more safe and environmental protection, can fully meet food grade requirements. According to the position of functional groups (that is, cross-linking points) contained in the molecular structure, liquid rubber with functional groups is often divided into two categories: one is the functional group at both ends of the molecular structure called teleclaved liquid rubber; The other is that the active functional groups are randomly distributed in the main chain, that is, those with functional groups in the molecular structure are called non-teleclaw-type liquid rubber. Of course, there are also those with both intermediate and terminal groups,

At present, the focus is on the remote claw type liquid rubber research. For liquid rubber, chain growth agents or crosslinkers with appropriate functional groups should be selected according to the active functional groups they contain.
