PTMEG Polytetramethylene Ether Glycol

PTMEG is a polymeric diol like ethylene glycol and its polymers but with a four carbon repeating unit instead of a two carbon repeating unit. A variety of polymeric molecular weights are possible. PTMEG is used to make high specification polyurethanes with enhanced properties such as hydrol-ysis and microbe resistance, good low temperature performance and excellent resistance to abra-sion and physical wear.

Examples of applications

Polymers formed using PTMEG include castable polyurethanes such as wheels and belts, thermo-plastic polyurethanes such as ski boots, hoses and sealants and a wide range of polyurethane coat-ings including fabric coatings and artificial leather.
