It's time to delve into the fascinating world of polyurethane production and the two chemical heavyweights that dominate this arena: MDI (Methylene Diphenyl Diisocyanate) and TDI (Toluene Diisocyanate). These chemical compounds play a crucial role in various industries, ranging from construction Read More

By combining additives like isocyanate and polyol, MDI is a polyurethane material. It stands out from other synthetic materials due to its exceptional qualities, wide range of variations, and numerous applications. It is also currently one of the materials with the highest rate of development.Light Read More

Introduction of TDIThe chemical formula of toluene diisocyanate (TDI), an organic substance, is CH3C6H3(NCO)2. Commercially significant isomers include 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7), two of the six potential isomers. Although 2,4-TDI is synthesized in its pure form, it is freque Read More

Diisocyanates come in two main varieties: MDI and TDI. These are helpful in the creation of polyurethane. Diisocyanates come in two main categories: aromatic diisocyanates and aliphatic diisocyanates. Aromatic diisocyanates come in the shapes of MDI and TDI.What is MDI?Methylenediphenyl diisocyanate Read More

An aromatic diisocyanate is methylene diphenyl diisocyanate (MDI). There are three common isomers: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. These are distinguished by the locations of the isocyanate groups around the rings. The most common isomer, commonly known as 4,4′-diphenylmethane diisocyanate, is the Read More

MDI is a polyurethane material synthesized by isocyanate, polyol, and their combined additives. With its excellent properties, various varieties, and broad uses, it is unique among many synthetic materials and has become one of the fastest-developing materials today.Diphenylmethane-4,4-diisocyanate Read More

Thermoplastic polyurethane (TPU) is a linear block polymer consisting of soft chain segments (long-chain oligomeric diols) and hard chain segments (diisocyanates and chain expanders). Due to the strong polarity of the hard chain segments, the microphase regions of the hard chain segments are formed Read More

With dwindling petrochemical resources, the urgent need for environmental protection and the continued rise in the price of petrochemical products, the development of soybean oil, castor oil and palm oil-based polyether polyols has become a research hotspot. Soybean oil polyether polyol Compared wi Read More

According to the latest data released by China Customs, from January to February 2023, China's cumulative exports of polymeric MDI amounted to 207,700 tons, up 46.9% year-on-year. Strong growth in export volume to Europe/Middle East countries By country, from January to February, the U.S. remained t Read More

Following BASF Monomers' announcement of its ambitious sustainability roadmap in February 2023, two of its production sites in Asia have now received ISCC+ certification. These certifications underscore the division's commitment to helping its global customers achieve their sustainability goals. Thi Read More

Every year, Belgians discard one million mattresses that end up in landfills and incinerators. The EU wants to recycle and reuse at least 55% of household waste, including mattresses, by 2025, while Belgium has decided to start mandatory recycling gradually in 2021. In this context, we can better un Read More

Polyether MDI prepolymer is a widely used material for polyurethane foam manufacturing. The following is the basic process of polyether MDI prepolymer production: Adding catalyst: Raw materials such as PTMEG, BDO, HDO are mixed in a reactor, and then a catalyst, usually an organotin compound, is add Read More
