Polyurethane foam is a polymer made of isocyanate and polyether as the main raw materials, mixed by special equipment and foamed by high-pressure spraying under the action of various additives such as foaming agents, catalysts, flame retardants, etc. There are two kinds of polyurethane foams: flexible foam and hard foam, the soft foam is an open-cell structure, and the hard foam is a closed-cell structure; Soft foam is divided into two types: crusty and non-crusty, and is commonly used in sofa furniture, pillows, cushions, toys, clothing and soundproof linings; Rigid foam is a new type of synthetic material with thermal insulation and waterproof functions, which is mainly used in building exterior wall insulation, roof waterproof and thermal insulation integration, cold storage thermal insulation, pipeline thermal insulation materials, building plates, refrigerated trucks and cold storage thermal insulation materials.

Anonymous users2024-01-23Foam is generally insulated, the heat absorption ability is basically very poor, and whether you will get cold when you sleep has little to do with the mat, it mainly depends on what quilt you cover.
Or buy it, you have to ask someone to do it or do it yourself, in fact, it is not cheaper than buying outside, first of all, the purchase price of raw materials is more expensive than that of manufacturers, and secondly, if you don't make a professional sofa, it is not firm, and the lines may not be straight. It's easier said than done.
No. It is related to the urge to urinate and the trace elements contained in the urine. The foam with a high impact will dissipate quickly within five seconds. If it does not dissipate for more than ten seconds, you should check your blood sugar to see if your blood sugar is standard.
Children should be careful, otherwise they will fall easily. If an adult is there, he quickly dry the foam for him.
It cannot be wiped with steel wool balls, nor can it be washed with corrosive detergents, such as disinfectants.
What you said is terrible, whose indoor temperature is forty or fifty degrees! Under normal circumstances, a decoration can be applied for more than ten years!
