Polytetramethylene glycol

Description:
Polytetramethylene glycol (PTMG), with the CAS number 25190-06-1, is a polyether polyol characterized by its flexible and hydrophilic properties. It is synthesized through the polymerization of tetrahydrofuran (THF) and is known for its low viscosity and excellent thermal stability. PTMG typically exhibits a high degree of elasticity and is soluble in a variety of organic solvents, making it suitable for diverse applications. Its molecular structure features repeating units of tetramethylene oxide, contributing to its unique properties. PTMG is commonly used in the production of polyurethane elastomers, adhesives, and coatings due to its ability to enhance flexibility and durability. Additionally, it is utilized in the formulation of thermoplastic elastomers and as a soft segment in segmented polyurethanes. The material is also recognized for its biocompatibility, which allows for potential applications in biomedical fields. Overall, PTMG is valued for its versatility and performance in various industrial applications.
