  • Polyether polyol types2


    In the previous article, we introduced polyether in the traditional sense, actually there are some species that can be used as polyether, here is a brief introduction 1. Polymer Polyol POP Vinyl polymer grafted polyether polyol, commonly known as polymer polyol (Polyether Polyol), or POP for short. Read More
  • Something about PTMEG


    The most popular polyether polyol utilized globally in the production of high-performance polyurethane elastomers is polytetramethylene ether glycol (PTMEG). PTMEG is utilized in a wide range of applications, including polyurethane elastomers, prepolymers, coatings, adhesives, cast polyurethane resi Read More
  • What is polytetramethylene ether diol used for?


    PTMEG is a waxy, white solid that melts to a clear, colorless, viscous liquid at or just below room temperature. Tetrahydrofuran (THF) is catalyzed into PTMEG by the polymerization process. The majority of PTMEG use worldwide is accounted for by spandex manufacturing. Other applications for polyuret Read More
  • Introduction to polytetramethylene ether diol​


    A white waxy solid, polytetramethylene ether diol is highly soluble in alcohol, ester, ketones, aromatics, and chlorinated hydrocarbons but insoluble in water and ester hydrocarbons. It turns into a translucent liquid when the temperature rises above room temperature.A polyether glycol containing hy Read More
  • Polyether polyol production process


    The main raw materials for the production of polyether polyols are starting agents, epoxides, catalysts, catalyst removers or deactivators, and post-treatment agents. The starting agents are low molecular compounds containing hydroxyl groups and low molecular compounds containing amino groups or hyd Read More
  • Overview of polyether polyols


    Polyether polyols are produced by the ring-opening polymerization of low molecular compounds containing active hydrogen, such as (alcohols, amines) as starting agents, with compounds containing epoxy structures under the action of catalysts. Polyether polyol can be generally divided into four catego Read More
  • Introduction to the production process of THF and PTMEG


    PTMEG, as the first major downstream of BDO, is a presence in the BDO industry that people cannot help but understand. Its downstream mainly includes spandex, polyurethane elastomer , polyether polyol and polyester ether copolymer elastomer (TPEE), etc., which are widely used. The production process Read More
  • A new player enters, a state-owned enterprise in Xinjiang lays out natural gas method BDO


    Karamay Fucheng Energy Natural Gas Comprehensive Utilization Project, with an estimated total investment of USD 500 million, is located in Baiyatan District Industrial Park and proposes to build 100,000 tons/year of 1,4-butanediol (BDO) plant, including 40,000 tons/year of acetylene, 100,000 tons/ye Read More
  • Thermoplastic polyurethane(TPU) in medical applications


    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
  • Recycling of polyurethane foam mattresses using chemical recovery


    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
  • BDO Industry Research Report 2023


    With the concentration of new production capacity, the trend of overcapacity is obvious. According to the specific analysis of the current BDO (1 4-Butanediol) production situation, the construction of BDO production units will be further accelerated in the next few years, and the increase in the nu Read More
  • Production process of polyether MDI prepolymer


    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
