Is the children's toy material a rare poison of PVC?

As we all know, there are various materials for children's toys, but some children's toys contain toxic substances. Some children's toy materials are made of PVC. Is that children's toy material PVC toxic? In terms of chemical composition, PVC has a certain influence on children's physical growth. But also toxic, so we should use such toys less. Is the material of children's toys a rare poison of PVC?

Plastic toys are generally not suitable for using PVC plastic raw materials. The chemical common name of this raw material is PVC, and the chlorine in PVC is highly toxic, so be careful when using it. However, most plastic toys in the domestic market are made of PVC materials. Among high-end toy products at home and abroad, such as Lego in Denmark and Yin Hui in China, Most of their plastic toys are made of ABS materials. Lego plastic toys are marked on the back of the products, using environmentally friendly ABS materials. According to the author's understanding, environmentally friendly ABS materials are added with accessories that are easily degraded by the natural environment or biodegradation. As for the accessories added, there are many kinds, such as vinyl acetate, starch and cellulose, which are more commonly used, and the price is naturally more expensive than ordinary ABS.

ABS material is a terpolymer of acrylonitrile, butadiene and styrene, where A stands for acrylonitrile, B stands for butadiene and S stands for styrene. Because it has three components, it has good performance. The surface of ABS resin products can be polished and high gloss products can be obtained. ABS material also has excellent low-temperature impact resistance, dimensional stability, wear resistance, chemical resistance and dyeability. So you can see why high-end toys look better, which has a lot to do with the characteristics of the materials used.

however, just because you see the ABS material, you can think that the product is safer and of higher quality. Nowadays, many modified ABS materials on the market are doped with nozzle materials and recycled materials. We know that the more toxic part of any plastic material comes from its additives, and the recycled plastics are mostly waste plastics that are melted or burned at high temperature, and then the additives are added again to shape them, and deeper colorants are added to cover the original color. It is conceivable that this recycled material contains much more toxic substances than other primary plastics.

even if the environmentally-friendly ABS material is used, even if the qualified standard certified by the European Union is so strict that the total mass percentage of all kinds of toxic substances should not exceed .1%, it cannot be denied that its harmful substances still exist, even though its proportion is relatively low and safer. Even the products with the best quality and safety guarantee are the same, not to mention those products produced under more restrictive conditions or even ignoring the restrictive standards?

in such an environment, besides expecting the research results of safer alternative materials and safer natural additives from the scientific and business circles, we should take the initiative to understand plastics, how to identify safer or more toxic plastic products, how to use them to reduce and avoid the threat of toxic substances to our health to a greater extent, and what kind of products produced by enterprises can be degraded by the natural environment, which can reduce the threat to the health of the earth, and take actions to support those with the concept of environmental sustainability and production capacity.

how can we judge whether the plastic toy materials in our hands are non-toxic? The method is as follows:

First, look at the brightness of plastic toys. If the brightness is poor, it is probably made of recycled plastic raw materials.

Second, look, the color depth. Generally speaking, the darker the color, the more toxic the plastic is. Another important reason for dyeing plastics is that the raw material is waste plastics, in order to cover up the original color.

Third, smell the plastic toys. If there is an irritating smell, you should pay attention. This material is likely to contain toxic chemicals.

fourthly, the plastic used to hold food is smooth and shiny. If it is not smooth, especially sticky, you must not hold food, because there are so many additives in it that you can't imagine, which may account for more than 5%.

finally, let's see if there is product certification for plastic toys. The domestic product certification is generally CCC. If there is no product, it is likely to be unqualified. Of course, we can't ignore some warning slogans on plastic toys! Is it good to use abs for children's toy materials?

abs is a high polymer, and these materials are not toxic in themselves, but some additives are bound to be added in the synthesis, processing and engineering of these things. These additives are small molecules that can be absorbed by the human body, which is the source of your so-called toxicity. Materials such as PC and PE/ABS are relatively better, while PVC is quite toxic. It is recommended to choose toys that meet EU standards. The younger children are, the more they should buy big brands of toys. As the saying goes, cheap goods are not good, and good goods are not cheap. The price of buying toys can still explain some problems.

In fact, most of the plastics are relatively stable, and it is difficult to react with other substances at room temperature, so there is no direct toxic effect on organisms.

Of course, different additives will be added to plastics due to different applications, but this different plastic is very different. Additives for plastics generally include inorganic fillers, glass fibers, pigments, antioxidants, anti-ultraviolet agents, plasticizers and so on. Inorganic fillers and glass fibers themselves are stable minerals and glasses, which are not toxic to human body. Antioxidants and anti-ultraviolet agents are generally used in small amounts, but only 1-2‰. Of course, they are also non-toxic or low-toxic. The plastic that is most likely to be dangerous to human body is PVC, and its additive content may even reach 6-7%, so it is difficult to ensure that it is harmless to human body.

ABS plastic is mostly used in household appliances, such as refrigerators, washing machines, air conditioners, microwave ovens, etc. We call it white electricity. Generally, additives are seldom used in this plastic, and pure ABS resin and toner are widely used. According to the present level of plastic industry, most of the toners are environmentally friendly products, which will have no impact on human body and environment. So don't worry about it, just use it with peace of mind.
