Does polyurethane foam material make pillows harmful to human body?
Polyurethane foam after finishing is no harm to the human body, so polyurethane foam pillows do not harm the human body. If it is genuine, just opened the pillow packaging, smell is normal, no harm to the human body, the use of one or two days after the disappearance of their own. Some people who are sensitive to the smell can put the pillow in the ventilation area and use it after 24 hours. It is better not to touch them directly, plus a mask. If you buy a pillow with a pungent taste of polyurethane, it is recommended to soak in water for more than 24 hours. After drying, it can be used to dispose of harmful residues and volatile odors.
Currently on the market can find all kinds of polyurethane production pillows, prices vary greatly, many consumers in the purchase after complaining does not rebound, with no pillow texture on the hand, as the weather changes in temperature pillow has become too hard or too soft.
Manufacturing process: slow rebound manufacturing process has two kinds: cutting and molding. Cutting is bought ready-made slow rebound sponge, cut into the pillow like, because the molding is not by cutting die + additives, without adding other additives even pure material polyurethane can only 40-70 density density. Is molded by adding additives with mold, foam, a series of processes such as die pressing, due to the addition of other additives, including soft foam, etc., so the density increase of about 70-100, feel good. The service life of the pillow has nothing to do with the process.
Rebound time: many consumers think that the longer the rebound time is, the better. This is a mistake. The better rebound time is about 3--5 seconds. Too short to get a slow rebound effect; too long can make your body stiff (think if you roll over, it hasn't been back up for half a day);
Density is the basic index of high-grade slow rebound material, the polyurethane density can be 70-100 in general molding process, and the cutting process can be 40-70. If this range is exceeded, it may be false. The market exists above the density of 130-150, which is almost unrealistic for pure polyurethane material production enterprises, the only possibility is to add other things, such as the ratio of polyurethane than the major, such as talcum powder and so on. From a professional polyurethane sponge technician's point of view, 110 density pure Pu is also possible, other possibilities are not present. In addition even the same density of products will be very different, is mainly the formulation, process and raw materials caused by the different, that is to say the high-grade tempur material is of high density, but only high density is not high-grade material;
