The main purpose of food grade silica gel is to contact with food. It has been praised as environmental protection. Representative of FDA, many customers have heard that food grade silica gel is also called platinum catalysis silica gel. I want to know if food grade silica gel is added with platinum. It turns out that food grade silicone really has platinum added catalyst!
Food grade silica gel has the following characteristics: food grade mold with small shrinkage rate. The temperature range of silica gel at -65 ° C - 350 ° C can be used for a long time and maintain its soft and elastic function. It has excellent electrical function and chemical stability, water resistance and resistance. Ozone, weathering resistance, non-corrosive, physiological lazy, non-toxic and tasteless, low line shortening rate, high clearness of finished products, good mold release, easy to operate and so on!
Food grade silica gel operation method: Mix A and B components evenly according to 1:1, and then water can be poured after vacuum degassing. The operating room temperature is determined by (0.5-3)H, vulcanization time (room temperature) 12-24H, Heating at 80-120 ° C can be vulcanized in tens of minutes. The room temperature quick drying operation time is less than 20 minutes and the vulcanization time is 1 hour. According to the demand can be red, yellow and other colors, and will not affect the properties of silicone, food-grade silicone details please consult Zhou S exclusive: hfdd1993!
Food grade silica gel is a high quality transparent food gel with added transparency and high transparency. It can withstand high temperature up to 350 ° C and can not be heated in a sealed environment. Food grade silica gel is made of high quality silica gel (new imported food grade silica gel raw material), processed by scientific formula and advanced technology. The product is characterized by softness, high temperature resistance and stability. Today, a healthy diet, food grade silicone has gradually replaced food grade plastics.
