As one of the six major synthetic materials, polyurethane has the largest variety and widest uses. It has developed the fastest in recent years, gradually replacing other synthetic materials in different fields. Driven by the stimulation of various industries such as construction, automobiles, new energy and environmental protection, the polyurethane market has a bright future, and major famous companies have entered this industry to seize this big cake.
Multiple industries are driving demand for polyurethane, and major companies are rushing to seize the market
Polyurethane products are widely used in transportation, furniture, home appliances, construction, shoes and clothing, aviation, medical and health, sports and other fields in the form of soft foam, hard foam, spandex, elastomer, slurry, sole solution, coating, adhesive and other forms. coming more and more widely.
The progress of the foreign polyurethane industry in 2014-2015. Although the polyurethane industry was affected to a certain extent by the continued downturn of the world economy in 2014-2015, with the rapid development of the construction field, automobile industry, electronic equipment, new energy and environmental protection industries, This has greatly boosted the demand for polyurethane products.
According to the China Polyurethane Industry Association, polyurethane is still growing at an annual rate of about 4.5% globally, with growth rates in refrigeration, footwear, textiles, leisure and other fields expected to reach 5.7%. In emerging countries in the Asia-Pacific region, the growth rate of polyurethane has reached double digits, supported by new downstream applications.
Progress of polyurethane raw materials
Emery Oleochemicals’ bio-based polyol plant in Cincinnati, Ohio, has completed equipment installation. This product can ensure both high performance and low cost, and can be used in automobiles, furniture, bedding and other major home appliance industries. Imuli signed an agreement with BioAmber of the United States. BioAmber will supply a new series of bio-based succinic acid products “Impranil” to replace adipic acid products.
BASF has successfully developed bio-based polytetrahydrofuran 1000 (Poly THF1000), which is mainly used to produce elastic spandex fibers and can also be used in thermoplastic polyurethane (TPU) and cast elastomers.
Covestro has built a polyol production line using carbon dioxide as raw material in Dormagen, Germany, with an annual production capacity of 5,000 tons. The innovative polyol produced contains about 20% carbon dioxide, which was first used in the production of polyurethane foam mattresses.
Huntsman Corporation of the United States has developed a new type of high-functionality aromatic polyester polyol Terol 649, which is mainly used in the production of rigid polyurethane foam, especially spray polyurethane foam.
Mitsubishi Chemical Corporation of Japan has exclusively developed a new type of bio-based polycarbonate diol (a high-efficiency polyol). Its composition is completely different from the existing polycarbonate diols on the market. The polyurethane products produced have high hardness and Excellent mechanical properties, low temperature resistance, chemical resistance and wear resistance.
Washington State University has developed technology to use similar vegetable oils, such as olive and linseed oil, to make polyurethane plastics that can be used in everything from insulating foam panels to tires, hoses and sealants.
The newly expanded Duranate hexamethylene diisocyanate (HDI)-based polyisocyanate production line of Japan’s Asahi Kasei Chemicals (AKC) subsidiary in Nantong, my country, has been put into operation, doubling the production capacity of Duranate HDI-based polyisocyanate. Polyurethane Product Progress Dow Chemical has developed a new type of foam memory pillow. This memory pillow adds a cooling gel layer that can help you fall asleep as quickly as possible and can adhere to the memory foam pillow for a long time. Viscoelastic polyurethane foams and gels use odorless adhesives.
BASF has successfully developed Slentite, the first high-performance organic aerogel polyurethane thermal insulation material. After drying the colloid, an organic aerogel with stable mechanical properties can be obtained. It is a forward-looking insulation material required for both new construction projects and renovation projects. all major properties.
Huntsman has developed RUBIFLEX Cocoon, a cool and breathable polyurethane soft foam, which is used in bedding, furniture and seating areas. The foam inflator has a unique humidity management function to further improve human comfort.
Bayer has launched a new spray foam based on Honeywell Solstice liquid blowing agent with good thermal insulation properties to reduce energy losses.
(www.gsiyuan.com ) is deeply involved in the segmented industry of polyurethane raw materials – amine catalysts; it develops and manufactures various types of amine catalysts; main products: ZF-22|ZF-20|CS90|DMDEE|BDMAEE|DMEA|DMAEE|DMACetc., suitable for sponge, molding, high rebound, self-knotting Leather, PU toys and various hard foam and semi-rigid foam and other end products.
