At present, most of the pet toys on the market are made of EVA materials, and all kinds of pet toys make dogs love them.
But did you know that they are exuding toxicity?
EVA itself is non-toxic and harmless and belongs to environmental protection materials. But at present, many domestic manufacturers choose some additives to save costs when using EVA, which can improve the foaming effect and reduce the amount of EVA used. These additives are basically toxic.
EVA itself is a small transparent particle, which needs to be foamed to make pet toys. The azodicarbonamide (AC) foaming agent used in the foaming process will decompose and recombine to form formamide under high temperature conditions.
There is currently no standard for pet toys in the country. Some manufacturers use a large amount of foaming agent. The more the amount added, the more foaming and lighter it is in order to save costs. At the same time, the residual formamide content will increase accordingly.
How harmful is formamide?
Formamide, also known as amino formaldehyde, is an industrial chemical. It has been classified as a reproductive toxic substance by the European Chemicals Agency. Toxicological studies have confirmed that formamide can be absorbed into the body through the respiratory tract, digestive tract and skin and mucous membranes; According to research, female mice ingested a certain concentration of formamide, their pregnancy rate, litter birth rate, and pup survival rate were significantly reduced, and the animal's nervous system, vascular system and liver were all damaged to varying degrees.
What are EVA products
The most common EVA products are children’s crawling mats. In order to understand the volatilization of formamide in children’s crawling mats, Jiangsu Quality Supervision has continuously monitored the volatilization of formamide in crawling mats. The results show that children who are normally placed in the room after opening For crawling mats, formamide can generally volatilize about 3% of its content after being placed for about 10 days; about 5% of its content can be volatilized after being placed for 20 days; the concentrated volatilization stage is about 30 days after opening, and generally 10% of its content can be volatilized. The remaining formamide evaporates slowly during use.
While pet toys directly contact the dog’s mouth, they can directly enter the body through the respiratory tract and digestive tract, and if formamide encounters high temperatures, ammonia gas will be produced. After the dog’s contact, the eyes and skin and mucous membranes will be damaged.
E-TPU physical foaming material is non-toxic and harmless
Wakanda Material Technology Company uses the material of Adidas boost sole to make a pet toy. This material is foamed TPU material. As the name suggests, TPU foam material is a product produced by physical foaming of TPU (thermoplastic polyurethane elastomer), commonly known as "Popcorn" (E-TPU). Generally, it can be divided into physical foaming and chemical foaming. Physical foaming refers to compressing gas into the raw material and then changing the pressure and temperature to make the product foam. It does not undergo a chemical reaction, so it is an environmentally friendly material; TPU The foaming ratio of the foam material can be as high as 8 times; it is non-toxic, tasteless, degradable, and more environmentally friendly; it has high strength, heat resistance, wear resistance, high resilience, and antibacterial properties.
A truly safe and non-toxic pet toy.
