White liquid silicone for making casting mold products

Supply of white liquid silicone for making casting mold products

White liquid silicone is easy to operate: it cures at room temperature, has excellent elasticity, and can be directly removed after molding concave and convex parts.
Lower cost: Compared to addition-type silicone, condensation-type silicone is generally more affordable, offering certain advantages in applications with strict cost control requirements.
Relatively higher shrinkage rate: During the condensation cross-linking process, low molecular substances such as ethanol are produced, which cause volume shrinkage of the vulcanized rubber when expelled. The shrinkage rate is typically around 0.3%, making it less suitable for casting molds with extremely high dimensional accuracy requirements.
Poor resistance to high temperatures and aging: White liquid silicone is prone to degradation and aging when exposed to heat, significantly affecting its service life. Therefore, its stability in high-temperature environments is inferior to that of addition-type silicone.
