The Impact of Hydroxyfluorosilicone Oil on the Durability of Mold Rubber

# The Impact of Hydroxyfluorosilicone Oil on the Durability of Mold Rubber I As the base material of mold rubber, medium-high viscosity hydroxyfluorosilicone oil significantly enhances the durability of mold rubber, which is mainly reflected in the following aspects: ## 1. Excellent Chemical Resistance The trifluoropropyl groups introduced by medium-high viscosity hydroxyfluorosilicone oil endow the mold rubber with excellent oil resistance and solvent resistance. This characteristic enables the mold rubber to maintain stable performance when in contact with various chemical substances, and it is not easily eroded or deformed. Compared with ordinary silicone rubber, fluorosilicone rubber performs remarkably well in terms of chemical resistance. Even in complex chemical environments, it can maintain its durability for a long time. ## 2. Higher Tear Strength and Mechanical Durability The tear strength of fluorosilicone rubber mold rubber is significantly higher than that of traditional materials (such as PDMS), approximately 2 to 3 times that of PDMS. This high tear strength makes the mold less likely to be damaged during repeated use and enables it to withstand higher mechanical stress, thus prolonging the service life of the mold. ## 3. Good Flexibility and Resilience The fluorosilicone rubber mold rubber has excellent flexibility and resilience, allowing it to maintain good performance in complex molding processes. This flexibility not only reduces the risk of mold damage during use but also enables it to adapt to a variety of molding processes, such as continuous molding and micro-replication. 请注意，原文中“约为PDMS的23倍”可能存在笔误，推测是2 - 3倍，上述翻译中按2 - 3倍处理，若实际就是23倍，请根据实际情况修改。
