Silicone is good for ice cream molds. Silicone products basically if the additives are no problem, can be completely food grade. Plastic is a chemical product, after high temperature will produce toxicity out.
Plastic and silicone are polymer materials, plastic and rubber, and silicone is just a branch of rubber. The definition of plastic is that it is hard at room temperature, while rubber is flexible and soft at room temperature in which brand of popsicle molds is good. Silicone rubber is generally more expensive, but not the most expensive.
Silicone are heat resistant and can be used for heating and baking. Ordinary condensed industrial-grade silicone is mostly temperature-resistant at about 100-150 degrees, and add molding food-grade silicone is temperature-resistant at about 250-300 degrees. Food-grade silicone is generally used to make food silicone molds, high-temperature baking is indispensable.
Extended information:
Ice cream molds using silica gel material and silica gel properties are inseparable.
Food-grade liquid silicone products generally have good transparency, strength, elasticity, yellowing resistance, stability and other characteristics, its viscosity performance is also more excellent, but also has a certain degree of heat resistance, cold resistance, corrosion resistance and so on. With these performance characteristics of food-grade liquid silicone products, can be used in many harsh environments for a long time without problems.
Food grade silicone is non-toxic, tasteless, high temperature advantages are widely used in food molds, chocolate molds, candy molds, precision casting, as well as carbon fiber composite materials, food cake molds, craft ceramics, printing, cloning of human organs, household appliances, lighting products, silicone ice grids, silicone nipples and so on.
