Advantages:

　　1. The molding silicone material to safety, environmental protection, the FDA food-grade certification

　　2. High and low temperature resistance (plus forming silica gel can be 200 degrees of heat-resistant)

　　3. The strong ultraviolet radiation resistance, aging resistance (condensation silicone 1, 2 years old, add silicone molding 5 years no change)

　　4. Small shrinkage: one over one thousand (which can be used for precision casting)

　　5. Good elasticity, good air permeability, good insulation

　　Disadvantages:

　　1. plus molding silicone poisoning occur easily, can not be used with condensation type, contain N, S, P and organic matter of Sn, As, Hg, Ph plasma compounds are easy to make and molding plastic poisoning, produce the phenomenon not curing.

　　2. compared with condensation silicone, forming adhesive performance is less.

　　3. Add forming silica gel at room temperature curing is influenced by temperature and weather change is larger.
