Nowadays, silicone products are becoming increasingly common in our daily lives because they are more environmentally friendly than plastic products, and have the advantages of being non-toxic, odorless, heat-resistant, and have a long lifespan. However, silicone products are also graded, such as food grade silicone, medical grade silicone, high temperature resistant grade silicone, odorless grade silicone, and so on. For different grades of silicone, the prices also vary greatly, and most people cannot distinguish any difference.
Therefore, this has given many unscrupulous merchants an opportunity to succeed. They will sell ordinary grade silicone products at high prices, using inferior ones as substitutes. Next, Guangzhou is teaching you some tips to distinguish between food grade and ordinary grade silicone products.
1. Forceful pulling method
Taking a silicone tube as an example, pinch both ends of the tube with your hand and then forcefully pull on both sides. The one with white on the silicone tube is a regular silicone tube, while the one without white is a food grade silicone tube. If we encounter a circular object like a cup lid, we 'fold' it in half. At the crease mark, the one that turns white is regular silicone, while the other is food grade silicone.
2. Nose sniffing
On the basis of the pulling method, the auxiliary smelling method. If the pulling turns white and has a pungent taste, it is a regular grade silicone product, and vice versa, it is a food grade product. However, there is a situation where it does not turn white when pulled up, but has a faint odor. It is also a food grade silicone product, as the vulcanization products generated during the manufacturer's production process do not affect product quality. At the same time, it can be eliminated on its own, so everyone can rest assured.
In addition, Guangzhou Zhengshun extends a bit, and the most important issue for judging a silicone product manufacturer is the "feel": the mold workmanship of the product, the vulcanization effect of the product, the color and smell of the silicone product are all the measurement standards for identifying a good silicone product.
