  What is the function of tetrahydrofuran? Tetrahydrofuran  can dissolve organic or inorganic substances and is widely used in chemicals or coatings. It can also be used in dyes. Tetrahydrofuran is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butylaniline. It is also used to make synthetic fibers, synthetic resins, synthetic rubber, and many polymer materials and precision tapes. and solvents for the electroplating industry. In the pharmaceutical industry, tetrahydrofuran can be used to produce Kebiqing, progesterone, rifomycin and as a pharmaceutical solvent. Tetrahydrofuran itself can be polycondensed (repolymerized by ring-opening initiated by cations) into polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubber that is wear-resistant, oil-resistant, has good low-temperature

  What is the function of polytetramethylene ether glycol: Spandex industry: The main field of  polytetramethylene ether glycol  is the spandex industry. Spandex is an elastic fiber with excellent properties and is mainly used in the production of underwear, swimwear, sportswear and socks. Elastomer: Polyurethane synthesized from polytetramethylene ether glycol. It has the advantages of hydrolysis resistance, aging resistance, good elasticity, and wear resistance. It is a raw material for special rubber and can be used to make aviation hoses, elevator tires, and industrial tapes. , sports shoes, medical prostheses, etc. Other fields: Polytetramethylene ether glycol has the advantages of high strength, good elasticity, and mildew resistance. It can also be used in the production of synthetic leather products, tires, conveyor belts, architectural coatings and floors, and protective materials.
