Are Polyurethane Pillows Harmful To People?

Polyurethane material is a kind of temperature-sensitive decompression material. This material is an open and relatively regular spherical cell tissue. Maintain a more appropriate body temperature. This material is a material that follows the contours of the human body. When using it, you will feel that there is no rebound. It is very comfortable. Therefore, using it will not cause harm to the human body. However, if you buy it Buying unqualified materials may have a negative impact on the body, so everyone should pay special attention when purchasing.

The benefits of polyurethane pillows

The benefits of this pillow are mainly reflected in its wide range of performance adjustment and strong adaptability; the product itself has good wear resistance; its mechanical strength is relatively large; its viscosity is good; its elasticity is very strong; The recovery effect is good; the low temperature flexibility is good; the service life is particularly long; the oil resistance effect is good; it can resist biological aging; the price is relatively reasonable.

It is not difficult to see from its benefits that it is a popular material, and it is also feasible to use it as a pillow. If you hope that you can choose a suitable pillow to meet your health care needs, then it is recommended to consider when purchasing a pillow Is it feasible to choose this material.

Are polyurethane pillows harmful to people? The answer is no, it is not only harmless to the body, but also has a certain effect in helping health care. If you want to be able to choose a suitable pillow to meet your health care needs, you can give priority to Consider it, however, be sure to pay attention when purchasing a pillow of this material to see if the product is qualified.

Buying Points

1. Whether it is pure material. Are the pillows made of 100% polyurethane and are talc added to increase the density? It is the secret of the industry’s production process and high density. More than 90% of the slow-rebound pillows on the market are produced from non-pure materials, so the density index is gradually difficult to measure the true quality of the pillow.

2. Whether it has passed the security inspection: slow rebound materials are chemicals, which are harmful to a certain extent in terms of chemical composition, so their safety indicators must be controlled in production. Whether the slow rebound toxic and harmful substances volatilize is fully utilized, see Whether the pillow is suitable depends on whether his safety inspection index passes? At present, the detection of slow rebound products includes the detection of toxic and harmful substances and the detection of pure materials.

3.Density: Density is one of the basic indicators of high-grade slow-rebound materials. Generally, the density of polyurethane in the molding process can be 70~150D, and the cutting process can be 40~100D. Due to technical bottlenecks and differences in equipment, The density of polyurethane produced in China is generally lower than 100D, while the highest abroad can reach 150D. Secondly, even products with the same density will vary greatly, mainly due to the difference in formula, process and raw materials. The elastic material must be high-density, but only high-density material is not necessarily a high-end material.

4.Manufacturing process: There are two manufacturing processes for slow rebound: cutting and molding. Cutting is the finished slow-rebound sponge that is bought, cut into the shape of a pillow, because the molding is based on cutting instead of mold + additives, no other additives are added, so even pure polyurethane density can only reach 40-70D. The molding is made by a series of processes such as adding additives, foaming, and mold pressing. Due to the addition of other additives, including chemical additives such as foaming and softening, the density increases to about 70-90D. ,Feel good. Remind everyone that the service life of pillows has nothing to do with craftsmanship.

5.Rebound time: The rebound time is also known as maintaining the shaping ability. Generally, the slower the rebound, the better the decompression ability. The rebound time of domestic memory foam is generally 3-5 seconds, and the rebound time of imported memory foam is more than 10 seconds.

6.Hand feeling and temperature sensing: The hand feeling and temperature feeling have little to do with the density of the pillow, mainly due to the mature technology of the factory (depending on the difference and the amount of additives added in the environment). Like the feeling of kneading dough, the slow rebound almost feels a little squeamish, or it is a little stiff.

7. Service life: Polyurethane memory foam pillow is mainly related to whether it is pure polyurethane and whether it is high-grade imported polyurethane. If it is pure imported polyurethane, it should not deform for more than 5 years, but if it is added to increase density and weight Because of raw materials such as talcum powder, the pillows are of poor quality and usually only last 2 years.
