There are open, closed, mixed and micropores. That is, the PU component is used to form a foam plastic product with a solid skin at a time by a special process. Plastic foam: It is a chemical material, the full name of polystyrene foam (Expanded Polystyrene) , Referred to as EPS). It can be used in shock-proof packaging of electrical appliances, instruments, handicrafts and other vulnerable valuables, as well as fast food packaging. Generally, polyurethane is semi-rigid The foam is made of pvc or abs and other plastics as the surface material, and PU semi-rigid foam is filled into it to form a sandwich material that looks like a 'sandwich', which is used as a decorative material in industries such as automobiles and furniture. , About a few tenths of a millimeter to 2. Light weight, soft, elastic, and not easy to transfer heat.
Widely used in automobiles, airplanes, chemicals, daily necessities and other industries, used as heat preservation, sound insulation, shockproof materials, as well as seat cushions, mattresses, medical machinery, sanitary products, sporting goods, etc. It is comparable, and some even surpass it, such as puncture resistance, etc.3mm, there is a porous structure under this strong skin. At present, soft self-skin PU foam plastic products are used in automobile steering wheels, armrests, headrests, bicycle seats, motorcycle seats, armrests and headrests of easy chairs, Doorknobs, spoilers, bumpers, etc.PMI foam rubber'>The difference between PMI foam and plastic foam: PMI foam rubber: a kind of rubber. What is polyurethane self-skinned PMI foam? Self-skinned foam, also known as whole-skin molded foam. It has the functions of shock resistance, impact mitigation, heat insulation, and sound insulation. Because of its light weight, sturdiness, shock absorption, low moisture absorption, easy forming, good water resistance, heat insulation, low price, etc.
Hard self-skinning PU products are also called ' 'Structural foam' is used in the furniture industry to make Wholesale China CASCELL® HF foam solid and beautiful frames for doors, window frames, tables, chairs, computers, typewriters, and pianos, or for sports equipment to make skis and surfboards. Self-skin foam does not require other Plastic is used as the surface material, relying on the foam component to form the surface material and the foam core material at one time during the foam molding. Difference: It is composed of different materials, Different characteristics and application range. Vulcanized rubber with a sponge-like porous structure. The foaming agent can be added to the raw rubber ( Such as ammonium carbonate, urea, azobisisobutyronitrile, etc. Also known as sponge rubber.
This kind of foam is different from general semi-rigid foam. . Its application prospects are very optimistic.) or the concentrated latex, which is stirred and blown into the air, and then vulcanized., it is widely used in packaging, heat preservation, waterproofing, heat insulation, shock absorption It is one of the most widely used plastics in the world today. The density of the skin is 1000-1200kg/m3, and the density of the core layer is several hundred kg/m3. Can be made Made into soft rubber or hard rubber products. 498 PMI foam, core material foam, high temperature resistant foam Is the foam of the core material foam flame retardant? New core material foam plastic plastic composite structure. Its outer skin is thicker. Polyester self-skinning PU products are mostly used in the shoe industry to make various leather shoes, overshoes, mining shoes, riding boots, etc. The synthetic rubber also has the characteristics of oil resistance, aging resistance, and chemical resistance. The mechanical properties of the PU skin are completely comparable to the olefin plastic skin
