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
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
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
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
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
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) 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
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
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
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
Spandex production, polyether polyol spandex, MDI and PTMEG belong to the main raw materials, DMAC is recyclable solvent, strictly speaking, in addition to these three substances other materials are auxiliary materials, mainly including amines, alcohol-based chain extenders, and a variety of additiv Read More
Bank collapse, crude oil plunge! Chemical market is directly brought to collapse, BDO, PTMEG and other raw materials fell more than 100$ in a single day! Last week, the financial risks triggered by Silicon Valley Bank had a significant impact on the commodity market, with international oil prices fa Read More
