The hazards of PVC floor mat additivesThe hazards of PVC floor mat additives.
As we all know, PVC (polyvinyl chloride) material itself is not toxic, but in the process of processing, some additives will be added to the PVC material to enhance the physical and mechanical properties of PVC products. However, due to price differences, additives are also different. Some additives can make up for the shortcomings of PVC materials, but they are harmful substances themselves, long-term use will cause greater harm to the human body.
For example, when producing PVC materials, manufacturers will add plasticizers to improve the ductility and flexibility of the product. Most small domestic manufacturers use DOP (dioctyl phthalate) and DBP (phthalic acid Dibutyl fat). Long-term exposure to DOP can cause harm to men's reproductive health; long-term exposure to DBP can cause mild allergic reactions. At present, the most mainstream is environmentally friendly plasticizers. Although the price is much higher than that of DOP and DBP, the physical and mechanical properties of products with environmentally friendly plasticizers are much higher than those of DOP and DBP. Environmental protection requirements can even meet EU standards. In the production process of products such as PVC floor mats, stabilizers are also indispensable additives, because only by adding stabilizers can PVC raw materials be well formed, otherwise, PVC particles will decompose at high temperatures. Throughout domestic manufacturers, phenolic and lead salt stabilizers are their preferred choice. Because these two types of stabilizers are cheap and have good effects, but phenols will emit irritating gas phenol when exposed to sunlight for a long time. This gas will react with proteins in the human body after entering the body. It is protein denaturation that makes cells Loss of activity; lead salt stabilizers in long-term contact with the human body will lead to excessive levels of lead in the human body and damage human health. In order to solve this problem, responsible manufacturers will use non-toxic stabilizers, while taking into account the stability effect, while ensuring the environmental protection of the product. The last, but most important point is the raw material itself. There are tens of thousands of PVC products on the market, but the price can differ by more than ten times or even hundreds of times. As the saying goes, there is no good goods cheap, but good goods are not cheap. Where does the difference in prices come from? As mentioned earlier, the raw material itself is the most important. Cheap PVC products, most of their raw materials are recycled old plastics, such as wire drawing materials for the clothing industry, waste VCD discs, and even medical waste recycling products (disposable infusion sets, syringes, blood transfusion sets), etc. These products pass through " The reuse of "Heart" manufacturers returns to the daily life of the public. What follows is that the harmful substances and germs they bring are also brought to consumers! Large-scale manufacturers start with raw materials, and each process is strictly controlled to strive for product quality without worries.
