Silica gel and silicone rubber have their own characteristics and advantages. Which material to choose depends on the specific use scenarios and needs.

Silica gel is usually used to make food containers, baking molds, baby bottles and so on, because it has excellent biocompatibility, 高温抗性, corrosion resistance and chemical stability.The transparency of silica gel is high, which is suitable for making high precision products, such as mobile phone shells, insoles and so on.In addition, silica gel also has the characteristics of good softness, good elasticity and good weather resistance.

Silicone rubber is widely used in the medical and food industry, such as medical instruments, 密封件, electronic components and so on, due to its excellent performance of high temperature resistance, low temperature resistance and chemical corrosion resistance.The hardness range of silicone rubber is wide, which can be used in extreme high and low temperature environments, and it also has the properties of oxidation resistance, radiation resistance and aging resistance.

From the perspective of food safety, silicone rubber does not contain carcinogens, while silicone rubber may contain trace amounts of organosilicon compounds, which have potential risks to human body.Therefore, the use of silicone rubber in food packaging is limited, while silicone rubber is widely used in the manufacturing of sunglasses, goggles and other eyewear.

一般来说, silicone and silicone rubber are safe materials, but different materials are used in different fields. If you need high temperature resistance, low temperature resistance and chemical corrosion resistance, you can choose silicone rubber; if you need to make transparent, soft and elastic products, it is recommended to choose silicone.
