Let's talk about the "all-natural" concept that is being heated up on the Internet:
The raw material of latex cotton may be rubber stock solution, which is the juice of rubber tree. The high one accounts for 90%, the low one may only account for 30%, and the low one 15%, that is, 0% (fully chemically synthesized latex). There is no latex cotton made of 100% rubber stock solution, but the "natural" concept of rubber stock solution has the advantage of commercial speculation.
Memory cotton 100% is fully chemically synthesized, and a few memory pillows use TDI (unstable, easy to react with moisture, and can be decomposed into toxic gas when heated or burned), which is often attacked by "poison" and is at a disadvantage. Now the industry uses safe MDI raw materials as memory pillows;
Of course, "natural" raw materials are all hype and of little value. The key to health is a small amount of harmful substances. But if there is a small amount of harmful substances, it is unhealthy and does not need to account for a lot. For example, TDI can leave a little bit in the finished products in memory cotton, which is definitely harmful. For example, other chemical raw materials must be added to latex, as long as there are harmful substances 1% or even lower than 1‰.
As a pillow, it is safe enough to detect harmful substances, especially if a large number of users use it for a long time in the early stage to see if there are any problems.
Memory pillow and latex pillow are mature products for more than 20 years. As bedding, there is no doubt that it needs to pass strict harmful substance testing, and it will certainly pass this testing. Then practical use: Now memory pillows and latex pillows are widely sold and used in the world, and each kind of conservative estimate has hundreds of millions of users, and the quantity is large enough. There are no reports of health problems of the two kinds of pillows. The only statistic that is harmful to health is latex, and 8-20% people will have allergic reactions. Therefore, in medicine, latex materials will not be designed to be implanted into the human body, but polyurethane materials will be designed to be implanted into the human body. But this is not the point, because latex pillows are protected by pillowcases and will not directly contact the skin, so they are generally fine.
Conclusion: In terms of health hazards, both of them are specious, and there is no problem. You can use it safely. If we want to pay attention to health and safety, we will pursue psychological effects.
