New discovery of a 40-year-old catalyst
Silicate-1 (TS-1) was developed nearly 40 years ago and has been successfully used as a catalyst to convert propylene to propylene oxide. This is an important commodity chemical, such as polyurethane. plastic. Now, a research team from ETH Zurich, the University of Cologne, Fritz-Haber-Institute and BASF has revealed surprisingly actual reaction mechanisms. Propylene oxide is an important commodity in the chemical industry, used in the production of plastics, antifreeze and hydraulic oil. The annual production of propylene oxide exceeds 11 million tons, of which more than 1 mill

Co-sponsored by China Synthetic Resin Supply and Marketing Association, China Automobile Industry Association, China Polyurethane Industry Association, China Fluorosilicon Organic Material Industry Association, and hosted by China Automotive Lightweight Non-metallic Materials Industry Alliance, "New Material Application Development Conference and Automotive Lightweight Non-metallic Material Industry Alliance Seminar" was held in Qingdao on November 21, 2019 Han Baole, deputy secretary-general of the China Polyurethane Association,`s report on the [Application of
Environmentally friendly soles shoe footwear,polyurethane
It breaks the shortcomings of traditional rubber and EVA soles. It has the advantages of lightweight and environmentally friendly recycling. It can also use 3D printing to achieve customized and personalized design of shoes, helping the PU shoe industry to enhance the competitiveness of the industry. It is the PU midsole application that Zhejiang Huafeng New Materials Co., Ltd. under Huafeng Group has been researching and developing with great concentration in recent years. Recently, Huafeng New Materials brought PU (polyurethane) midsole application innovation trend program to
The film forming mechanism of water-based two-component polyurethane
The film forming mechanism of water-based two-component polyurethane is different from thermoplastic polymer solution, and also different from thermoplastic polymer dispersion and thermosetting polymer solution. From the composition point of view, it is related to both the particle coalescence mechanism of the thermoplastic polymer dispersion and the film formation mechanism of the thermosetting polymer solution's crosslinking reaction. During the film forming process: Volatilization of volatile matter (solvent, water); Co-coagulation
Ashland Increases 1,4-Butanediol, Derivatives Prices in Europe
Ashland is increasing prices on 1,4-Butanediol (BDO) and several derivative products as indicated below:
Recently, researchers at the University of California, Berkeley invented a new chemical process that can recycle waste plastic bags (mainly polyethylene PE) and convert them into more valuable adhesives, realizing the upgrade of polyethylene Recycling. According to reports, the researchers used a catalyst based on ruthenium (gold balls in the middle) to add specific chemical groups (in this case, OH (red)) to the polyethylene polymer chain to form an oxidized poly Vinyl. It can be firmly attached to the metal and retains the unique plastic characteristics of polyethylene. Resear
New method for chemical recycling of polyurethane waste
Polyurethane is a polymer formed by the reaction of isocyanate and polyol. These polymers have a wide range of hardness, hardness and density, and are usually used to manufacture high-resilience foam seats, rigid foam insulation boards, foam seats and gaskets, elastic wheels and tires, high-performance adhesives and surface coatings. And sealant. In terms of quantity, polyurethane foam is the most important as a soft or rigid foam, and the furniture market is the most important area. The global annual demand for furniture cushions, carpet cushions and mattresse
The arrival of a new era of polyurethane 3D printing
In the global 3D printing industry, we occasionally encounter some start-up companies whose technology may seem trivial, but the potential is huge. This not only requires a good idea, but more importantly, to find the real pain points. This is not as easy as it sounds. More importantly, the company must have the technology to solve these problems. Chromatic 3D Materials' work on thermoset materials, especially polyurethane extrusion, is a good example. Being able to use one of the most commonly used materials in the world for 3D printing proficiently and at low cost will bring huge market oppo
Use waste plastic bottles to produce polyurethane raw materials
Polyurethane is very versatile. This material formed by the reaction of polyols and diisocyanates can be made into skateboard wheels, rigid structures of automobiles, memory foams for mattresses, and insulation materials for refrigerators and buildings. However, the properties of polyurethane-the properties of tightly bound molecules and usually irreversibly combined with cross-linked materials, and remeltable thermoplastics such as polyethylene terephthalate (PET) or polypropylene (PP) In comparison, its recycling is a challenge. Plastic manufacturers are trying
The global waterborne coating additives market will reach US$4.11 billion by 2022
The US research institute Hexa Reports released a new research report showing that by 2022, the global water-based coating additives market is expected to reach 4.11 billion U.S. dollars, and the output will reach 801,000 tons, with a compound annual growth rate of 5.5%. Due to people's preference for low-toxicity, low-voc coatings and the increasing requirements of formulation technology for multifunctional additives, it is expected that the water-based coating additives market will develop well in the future. In the very mature North America and European area of architectural
Ethiopian Ambassador to China visited China Leather and Footwear Research Institute

TPU makes a big difference in shoe materials
TPU is synthesized from isocyanate and polyol. The isocyanate gives the strength of the TPU material, and the polyol gives the flexibility of the TPU material. With different formulations of raw materials, the hardness of TPU can be adjusted, and TPU has excellent wear resistance, which is very suitable for shoemaking. Outsole: The outermost layer of sole that touches the ground is called the outsole. The most important requirements for the outsole are non-slip and wear-resistant. Traditional shoe outsoles are made of rubber or EVA. Due to the wear resistance of TPU, it has grad
