b.      When the hardness of silicon rubber is higher than 50 shore A, the tension and the tear strength of silicon rubber will reduce, and the solidified silicon mold will be easily broken.

a.      When the hardness of silicon rubber is lower than 15 shore A, the tension, the tear strength, the ageing resistance, acid and alkali-resistance of silicon rubber will reduce respectively. 

 Limitations:

(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.)
  

If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.

Molding silicone rubber operations

Molding silicone rubber is white or red flowing liquid with general hardness of 22-50A

light viscosity, pourable effort, good fluidity, easy-operation, good tension and high tear strength,high reproduction times.
