Do you know the difference between "plastic" and "silicone"?silicone baby bottle brush

　　Many friends are worried about choosing a lot of plastic products. They can't tell the difference between plastic, silicone, rubber, PU, PC and other materials. I don't know which material is practical and environmentally friendly. However, with the emergence of some smart products and creative gadgets in recent years and the trend of electronic products, smart products have gradually been pushed to the forefront of the market, and faced with the novice who do not know much about the production process and the quality of the materials used I am confused and can't tell whether it is better to choose silicone products or plastic products, so today I will reveal their different differences, advantages and disadvantages for everyone!

　　First of all, the classification of silicone and plastic is very different, and the processes used are also different. From the perspective of silicone products, many of our daily necessities are made of food-grade high-transparency silicone material, which is also a kind of rubber and plastic material. However, as early as the 19th century, studies have shown that it belongs to the most environmentally friendly and basically harmless synthetic rubber among rubber and plastic materials. It is superior to plastic material, and the cost is lower than plastic in terms of process. After the secondary flow molding, the popularity, elasticity, tensile force and tear resistance of the product will gradually be reflected in the use process of the product. The outstanding advantage is that it belongs to no Toxic and environmentally friendly products, there is no conflict on the body, the disadvantage is that the air permeability is not good, and the electrostatic adsorption force will be too strong!

　　Plastic materials belong to our common PU, PC and other materials. In production, extrusion process, injection process and blow molding process are used. The main advantages are wear resistance, oil resistance, transparency, good elasticity, excellent electrical insulation, extensibility, and size. Stability and chemical resistance, heat resistance and cold resistance, and also have the advantages of self-extinguishing, flame retardant, coloring and so on. In addition, to meet the requirements of product function, quality and appearance, the design of plastic parts must make the injection mold easy to process and low in cost. At the same time, the part injection time is short, the efficiency is high, the part defects are few, and the quality is high. This is the design for injection molding. This section will detail the plastic part design guidelines so that the plastic part design is geared towards injection molding. The difference from silicone rubber products is the coloring problem. When compounding the solvent, some polyvinyl chlorides release harmful substances in the case of unequal compounds and want to secrete interferon, which endangers the safety problem.
