Flexible polyurethane foam is a polymer produced from the reaction of polyols and isocyanates. It is characterized by a cellular structure with low density, good elastic recovery, sound absorption, air permeability, heat preservation and other properties.
Polyurethane flexible foam has always been the preferred material for car seats due to its durability and comfort, and the material has even greater potential: it can also help car manufacturers reduce CO2 emissions and the use of fossil resources in the production of car seat cushions significantly.
With the expansion of factory and the continuous improvement of production capacity, QICHEN company has increased its investment in R&D, introduced new equipments and a group of outstanding technical personnel, strengthened the R&D team, and committed to providing customers with better products, better technical support, more competitive prices, more convenient and efficient services~
Polyurethane spraying is a new type of synthetic material with the integration of thermal insulation and waterproof functions. Because of its low thermal conductivity, light weight, good heat resistance, efficient insulation, good sealing, easy to bond with concrete, wall, wood and other substrates, no cracking, no shedding, no corrosion, etc. For various shapes of substrates, whether it is a plane, elevation or top surface, whether it is a round, spherical or other irregular shape of complex objects, can be sprayed foaming processing directly. Therefore, it is often used in cold storage, exterior walls, walls, building insulation, equipment and pipeline insulation, storage tank insulation, breeding farms, steel structure workshops, light steel villas and other projects of thermal insulation and spraying construction.
Cast polyurethane (CPU) is the most widely used and most produced polyurethane elastomer. It is a process in which oligomeric polyols, isocyanates, and chain extenders (crosslinkers) are used as raw materials, react polyols with isocyanates to form low-molecular weight prepolymers at specific temperatures, and then add chain extenders to form cast polyurethane. Because of its superior comprehensive performance, a wide range of hardness, high strength and elongation, excellent wear resistance,etc, it is becoming more and more popular.
Sustainability is one of the recent development themes in the polyurethane industry, and electric vehicle industry is bringing the new application requirements for polyurethane. This reflects the strong interest in sustainable products in the electric vehicle industry and will be a significant opportunity for the polyurethane industry.
Recently, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development proposed the "Work Program for Accelerating Energy Conservation and Carbon Reduction in the Construction Sector" to improve the energy efficiency continuously, reduce carbon emissions and accelerate the improvement of the quality of green and low-carbon development in the construction sector.
In today's world, as the importance of environmental protection becomes more prominent, all industrials are looking for more sustainable and eco-friendly production methods. PU as a kind of material widely used in construction, home furnishing, automobile and other fields, which has attracted much attention in the environmental protection of its production and use. In recent years, polyurethane low-free MDI and TDI prepolymers are quietly changing the ecology of the polyurethane industry and contributing to our green life.
Nano polyurethane The so-called "nano polyurethane" refers to the organic/inorganic nanocomposite material formed by the inorganic filler dispersed in the polyurethane materials in nano size, and which has excellent properties that the general polyurethane materials does not have. Different fillers can be filled into different polyurethane material systems to make a lot of polyurethane composite systems, polyurethane nanocomposite coatings also have special properties or functions that the original components do not have, providing new possibilities for the preparation of high-performance new materials. so it is a new high-tech new material, which has broad prospects for applications.
When everyone is full of confidence that China's polyurethane industry has entered a stage of rapid development, we should pay more attention to the future development direction of polyurethane.
