Silicone spatula is non-toxic when used in a suitable temperature range, and it may have a certain impact on human body if it exceeds a suitable temperature range. The qualified silica gel tongue depressor sold in the market generally adopts food-grade silica gel, which can withstand the temperature of -40℃~230℃, and there is generally no problem in normal use at low and high temperatures.
Food-grade silica gel is generally refined after sterilization. Because it is not easy to stain and easy to clean, it has been widely used in children's pacifiers and kitchen utensils.
Matters needing attention in purchasing silicone spatula
1, carefully observe the packaging of silicone spatula products. Read the identification label clearly, such as material, model, implementation standard, quality grade and three guarantees, and whether there is information such as the name, address and certificate of the production (distribution) unit. Don't buy "three noes" products cheaply and avoid buying products without producer information.
2. Look at the color and smell. The key factor to determine the performance of silicone tongue depressor is the quality of raw materials. High-quality silicone spatula has pure appearance color, and the surface of the product will not be flawed and looks smooth. The silicone spatula produced from inferior silicone raw materials has a rough surface and a pungent smell.
3. Pay attention to the touch of the silicone spatula. Good quality silicone tongue depressor has comfortable and delicate overall touch, good flexibility and elasticity, and is not easy to deform.
