Liquid silica gel is relative to solid high-temperature vulcanized silicone rubber. It is a liquid rubber with the characteristics of good fluidity fast vulcanization. It is safer environmentally friendly, can fully meet the requirements of food-grade silica gel.

Liquid silica gel often divides liquid rubber with functional groups into two categories according to the position of the functional groups (ie, crosslinking points) contained in the molecular structure: one is telechelic liquid rubber with functional groups at both ends of the molecular structure; the other Class is the random distribution of active functional groups in the main chain, that is, those with functional groups in the molecular structure are called non-telechelic liquid rubber.

Of course, there are also liquid rubbers with both intermediate functional groups end groups. At present, the focus is on teleclaw liquid rubber. For liquid rubber, a chain extender crosslinking agent with appropriate functional groups should be selected according to the active functional groups it contains.
