Latex mold

Latex molds are silicone molds, generally composed of five components: base rubber, crosslinking agent, catalyst, filler, and additives. In theory, as long as there are the first three components, mold silicone can be made, but to obtain a certain strength, "filler" is generally necessary, and "filler" depends on the situation. Usually, the base adhesive, crosslinking agent, and filler are made into one component, while the catalyst is used as a separate component. The ratio of catalyst component to main rubber component is generally between 1% -3%, and the reaction rate of the gel reaction can be adjusted by adjusting the catalyst ratio.

Characteristics:

① Mold silicone rubber should have good operational performance.

② Silicone has better flowability and low viscosity, making it easy to operate.

③ The smaller the shrinkage rate of silicone rubber, the better.

④ Silicone rubber has better tensile strength.

⑤ The silicone mold made should not deform.

⑥ The hardness of silicone rubber should be suitable for product use.

⑦ High temperature resistance, multiple mold turns, longer service life, better, acid, alkali, and aging resistance.
