Many people mistakenly believe that PVC is a substance. In fact, PVC, also called polyvinyl chloride, is environmentally friendly, non-toxic and renewable. It is widely used in people's daily life, such as table food, medical bags, etc., so there is no need to worry about environmental protection issues.The global usage of PVC board ranks second among all synthetic materials.
According to statistics, in 1995 alone, the output of PVC in Europe was about 5million tons and the consumption was 5.3 million tons. In Germany, the average output and consumption of PVC is 1.4 million tons.
PVC is being produced and applied all over the world, with a growth rate of 4%. The growth rate of PVC in Southeast Asia is particularly remarkable, which is attributed to the urgent needs of infrastructure construction in Southeast Asian countries. PVC is suitable for making 3D surface facial mask.However, due to the insufficient characteristics of PVC board materials, people need to add a large number of additives to stabilize PVC materials. In fact, pure PVC is non-toxic, but after modification with a large number of additives, PVC materials react with toxic substances under the comprehensive action of various additives, that is to say, these additives can turn PVC materials into softer chemical additives phthalein. After a large amount of PVC material is used, it will have a great impact on the inner kidney and liver of the human body.
Urea formaldehyde and melamine formaldehyde are contained in PVC board. When we manufacture PVC materials, their reaction is incomplete, which will lead to a large amount of free formaldehyde in PVC materials, which is a kind of protoplasm poison of cells. If you use a PVC bowl to hold hot food, it is easy to cause some cells of the human body to deteriorate after eating, which is harmful to human health. There is chlorine in PVC material, which will produce a kind of poison when we burn.Is PVC board poisonous? In fact, the product itself is non-toxic, and PVC used in green decorative materials will not cause any harm to human body.
