Friends who don't know mistakenly think that silicone baby spoons will have toxic substances. In fact, silicone products are high and low temperature materials. They are vulcanized and molded at a high temperature of more than 200 degrees. They can be sterilized by high temperature boiling water and are free of toxic substances. , And regular food grade silica gel will not turn yellow or discolor. But can the silicone spoon be used in case it turns yellow? In fact, it is possible. Let's talk about the reason why the silicone spoon turns yellow.

Silicone spoon

The product has moderate hardness, which can appropriately relieve the excitement and emotion of children when eating. It is also soft, so there is no need to worry about piercing the corner of the child’s mouth. No matter how bite it is, it will not bite, so there is no need to worry about being swallowed into the stomach. Silicone spoons are environmentally friendly products and must be tested for green, safety and environmental protection. Therefore, they use food-grade silicone raw material platinum vulcanizing agent, and high-transparent raw materials are added with various color glues and screen printing processes to become children's favorite styles. It is also a guarantee for parents to rest assured.

Ordinary genuine silicone products generally will not turn yellow after being used in the market for a few years. However, during the reproduction process, some newly formed silicone products have turned yellow or discolored. Why? There are several ways to make silicone for the first time.

Because the mold temperature is too high or the vulcanization time is too long, the vulcanizing agent and raw materials after the second vulcanization, the performance of the sulfide is unstable, because the vulcanizing agent belongs to the ordinary type, and the anti-yellowing type is also called crystal vulcanizing agent, ordinary vulcanizing agent Used for some non-exposed silicone products with darker color or lower color requirements. The exposed silicone products are lighter in color and better in color. Sometimes an anti-yellow vulcanizing agent is added to the rubber, but the product is produced If it is still yellow, it may be that the raw materials of the silicone product factory are too poor, so the raw materials must be of high quality.

The production of silicone products is a complex process. In addition to mechanical and human factors, the quality of products is not only mechanical and human factors, but the key is to discover and solve quality problems. Therefore, to reduce production defects, the key is to maintain the normal operation of the machine, the good working condition of the mold, and strengthen the operating skills and quality awareness training of the operators and quality control personnel.
