There are many silicone products in our lives, silicone products are currently one of the most common supplies in our lives, but there are also many fake silicone products on the market.   1. Color: This color is not the color of the product itself, but whether the product has turned yellow. If it is a good silicone product, such as food-grade silicone products, it has the characteristics of non-yellowing, aging resistance, and non-degradation. 2. Feel: Feel is very important, whether it is stretching, resilience, deformation and toughness strength of silicone products are very important, if you can meet the above several properties are basically excellent material. These are generally used for high-end products as well as brand name products. 3. Smell Smell with your nose. According to the characteristics of silica gel material, it is non-toxic and tasteless. Therefore, the real silicone products made of silicone are environmentally friendly and odorless. If it is fake and shoddy silicone products, smell with your nose close, you will smell a pungent odor. 4. Transparency Observe the transparency of the product. The silicone material is colorless and transparent, so the product transparency is higher, since it is to make a color product, the transparency is also very high. Because of the transparency of the product, it can be seen whether there are impurities in the product. And rubber, latex and other impurities because the content of more, so can not do transparent color products. 5, stretching products Stretch the silicone product hard. This is distinguished by tensile toughness. Force to stretch silicone products, if it is a real silicone product, when the force is stretched, there will be no white phenomenon. If it is made with ordinary silica gel or inferior silica gel material, the stretching place will appear white phenomenon. Because good silica gel, soft and comfortable, elastic and other characteristics. 6, open flame burning: This method is the most simple and effective method. Generally, high-quality silica gel products will be different from other rubber materials after burning, high-quality materials will emit white smoke, the product surface will appear white fog phenomenon after burning, completely burned white powder, completely colorless and tasteless. And different materials will appear yellow or black residue.   In summary, high-quality silicone products are harmless, but inferior or fake silicone products are harmful to the human body. After reading the above, we must also know how to distinguish the true and false silicone products.

Resilience: also known as resilience, or impact elasticity, elasticity, is also an important performance indicator to measure rubber elasticity. With the pendulum at a certain height of impact rubber, the ratio of the height of the rebound and the original height is called the rebound rate, expressed as a percentage (%), the greater the value, the higher the elasticity of rubber.   Tear permanent deformation: referred to as permanent deformation, is also an important indicator to measure rubber elasticity. After the rubber is stretched and broken, it is parked for a certain time (usually 3 minutes), and the ratio of the increased length of the deformation part to the original length is expressed as a percentage (%). The smaller the straight, the better the elasticity of the rubber. In addition, the elasticity of rubber can also be measured by compression permanent deformation.   Fixed elongation strength: also known as fixed elongation strength. It refers to the force required per unit area when the rubber is extended to a certain length, that is, when it is extended to 100%, 200%, 300%, 500%. In terms of N/cm2. This is an important mechanical index to measure the strength and toughness of rubber, the greater the value, the better the tolerance of rubber, indicating that this rubber is not easy to produce elastic deformation.
