What are the advantages of silicone products compared to PVC products? What are the differences between the two in terms of performance and use? In terms of use alone, the two have intersections in gifts, especially silicone products. In the Yiwu Commodity Market, some gifts or kitchen utensils produced by silicone can be seen everywhere, and PVC products are also involved in the field of gifts, but PVC materials are special. Sex, there is no more market for silicone gifts.
1. From the perspective of the material itself, PVC products are mainly made of PVC powder (polyvinyl chloride), oil and color paste mixed and prepared into raw materials, which are made by heating and cooling through micro-injection and dispensing process. Silicone products are mainly made of silicone raw materials plus color masterbatch. Some chemical elements such as color paste are pressed and formulated by a rubber mixer to make the required raw materials, which are heated and cooled by an oil press in a mold. Silica gel is divided into liquid silica gel and solid silica gel.
2. From the appearance of the product, the PVC product is less rough than the silicone product, and has a slight unpleasant smell. The surface of the silicone product is smooth, colored and tasteless.
3. Judging from the hand feel, silicone products are softer in texture, better in toughness and elasticity, and PVC soft rubber is relatively less hard, but the hardness of both can be adjusted.
4. PVC materials include ordinary materials and environmental protection materials, also called ATBC-PVC, while silica gel itself is environmentally friendly, and the market prospect of silica gel products is still very good.
I believe that after seeing the above 4 points, everyone will understand the difference between these two types more clearly.
The cost of silicone material is higher than that of PVC, and the cost of liquid silicone is higher than that of solid silicone. Silicone products have good weather resistance and will not turn yellow, and can pass the test of export products from countries such as the European Union.
About silicone rubber products
The production of silicone rubber products is a complex process, and the quality is not only good or bad except for machine and human factors. Intermediate inspections are the key to finding and resolving major product quality issues. Therefore, maintaining the normal operation of the machine, the good working condition of the mold, and strengthening the operation skills and quality awareness training of operators and quality control personnel are the key to reducing production defects and the benefit of the enterprise.
