Plastic and silica gel are both polymer materials, plastic and rubber, and silica gel is only a branch of rubber. The definition of plastic is hard at room temperature, while rubber is elastic and soft at the good temperature of indoor popsicle mold. Silicone rubber is generally more expensive, but not the most expensive.
Silica gel is resistant to high temperature and can be used for heating and baking. The temperature resistance of ordinary concentrated industrial grade silica gel is mostly around 100- 150 degrees, and the additive food grade silica gel is around 250-300 degrees. Food-grade silica gel is generally used to make food-grade silica gel molds, and high-temperature baking is essential.
Extended data:
The material of silica gel for ice cream mold is inseparable from the characteristics of silica gel.
Food-grade liquid silica gel products generally have good transparency, strength, elasticity, yellowing resistance, stability and other characteristics, and their viscosity performance is also excellent, and they also have certain heat resistance, cold resistance and corrosion resistance. Food-grade liquid silica gel products with these properties can be used for a long time in many harsh environments without problems.
Food-grade silica gel has the advantages of non-toxic, tasteless and high temperature resistance, and is widely used in food replication molds, chocolate molds, candy molds, precision casting, carbon fiber composite materials, food cake molds, craft ceramics, printing, human organ cloning, household appliances, lighting products, silica gel ice cubes, silica gel pacifiers and so on.
