Polyurethane Shoe Sole
Polyurethane shoe soles have a lot of advantages: low density, soft texture, comfortable and lightweight; good dimensional stability, long storage life; excellent abrasion resistance, resistance to flexing; excellent shock absorption, anti-skid performance; good temperature resistance; good chemical resistance and so on. Polyurethane is mostly used in the manufacture of high-grade leather shoes, sports shoes, travel shoes and so on.
Polyurethane slurry
Divided into two categories, wet and dry, is a polymer solution system, transparent or cloudy appearance, the solid content of about (30-35)%, that is to say, (65-70)% of them are solvents, simply put, 1 ton of slurry contains (650-700) kg of solvents, for the dry is to contain so much toluene and butanone, the amount of toluene is larger, because toluene is used more, because of the good chemical resistance. Toluene, toluene dosage is larger, because the solvency properties of toluene is better, for the wet process is to contain 650-700 kilograms of pure DMF, so for the slurry, such as toluene, DMF, the price of the price changes largely affect the cost of the slurry, the reason is very simple to account for the amount of the proportion of the major.
Polyurethane slurry is used as a coating to prepare polyurethane synthetic leather and artificial leather. Polyurethane synthetic leather has a soft, natural luster, soft touch, leather feel strong appearance, with excellent bonding performance with the substrate, wear resistance, flex resistance, anti-aging, good resistance to mold and other excellent mechanical properties, but also has a good cold resistance, breathable, washable, easy to process, inexpensive price, etc., is the most ideal alternative to natural leather, widely used in apparel, footwear, bags, furniture, Sports and other industries. Where the application of leather, it can be replaced, but also can be applied to leather can not be applied in the field of leather, leather market is easily affected by the animal (cattle, sheep, pigs, etc. market, mad cow disease).
Dry polyurethane slurry - in the process of application, by heating evaporation of the slurry in the solvent evaporated, the solvent is mostly used toluene, butanone, evaporated solvent can not be recycled, not only pollution of the environment, but also caused unnecessary waste.
Wet polyurethane slurry - as the processing is used to extract DMF with water (the reason is that DMF and water have infinite solubility), more environmentally friendly, and the production of synthetic leather has good moisture permeability, breathability, soft feel, plump, light, and more rich in natural leather style and appearance, so the The development speed is extremely amazing.
Polyurethane fiber (Spandex, referred to as spandex)
Spandex's excellent performance: outstanding high elasticity, spandex's high elasticity is currently all elastic fibers can not be compared to its elongation at break is greater than 400%, up to 800%, even in 300% tensile deformation, rebound recovery is still above 95%; excellent tensile strength, tear strength; weather resistance, strong resistance to ultraviolet irradiation; chemical resistance, washing resistance; good affinity with dyes.
Spandex has been widely used in textiles, is a high value-added new textile materials, the use of its form there are four main: bare silk, core yarn, coated yarn, co-twisted yarn. Such as stockings, swimsuits, dancewear, Lycra (cotton covered spandex yarn), clothing, etc. In traditional textiles, just add less than 10% of the number of spandex, you can make the traditional textile grade greatly improved, showing a soft, comfortable, beautiful, elegant style.
Polyurethane Coatings (PU Coatings)
Polyurethane coatings are mainly used in the following areas: aircraft, ship, vehicle coating; wood, plastic, rubber, leather surface coating; building coating; anti-corrosion coating, and so on.
Waterborne polyurethane coatings - with water as the main medium, featuring low VOC content, low or no environmental pollution, and easy construction - are one of the main substitutes for solventborne coatings. It has been widely used in many fields, such as: (1) wood paint and wood floor paint; (2) paper coating; (3) architectural coatings; (4) leather coating; (5) fabric coating, and so on.
Polyurethane Adhesives (PU Adhesives)
Polyurethane adhesives contain very strong polarity and chemical activity of -NCO- (isocyanate), -NHCOO- (carbamate group), with the substrate containing active hydrogen, such as foam, plastics, wood, leather, fabrics, paper, ceramics, and other porous materials, as well as metal, glass, rubber, Plastics and other materials with smooth surfaces have excellent chemical adhesion;
With excellent shear strength and impact resistance, suitable for a variety of structural bonding areas, and has excellent flexibility characteristics;
Polyurethane adhesive has excellent rubber properties, can adapt to different coefficients of thermal expansion of the substrate adhesion, it is formed between the substrate with a soft - hard transition layer, not only strong adhesion, but also has excellent adhesive properties. It forms a soft-hard transition layer between the substrates, which not only has strong adhesive force, but also has excellent cushioning and vibration damping functions;
The low and ultra-low temperature performance of polyurethane adhesives exceeds that of all other types of adhesives;
Waterborne Polyurethane Adhesives--Waterborne Polyurethane Adhesives are characterized by low VOC content, low or no environmental pollution, and are non-flammable, which is a key development area for polyurethane adhesives. the key development direction of polyurethane adhesives.
Polyurethane Sealants (PU Sealants)
Sealants are used to fill the void (holes, joints, seams, etc.) of the material, both bonding and sealing two functions. Polyurethane sealant and silicone sealant, polysulfide sealant constitutes the current three varieties of high-grade sealant.
Polyurethane sealant is widely used in civil engineering construction, transportation and other industries:
Application in construction - doors, windows, glass, etc., filling seal;
