Polytetramethylene Ether Glycol Polyol 650 (PTMEG 650) is a specialty liquid difunctional polyether polyol with a softening point of about 11˚C. It is used as the soft (flexible) segment of high-performance polyurethane, polyurea, and co-polyester & co-polyamide elastomers, where higher durometer hardness values and tensile & tear strengths are required. PTMEG 650 is known for its lower viscosity, easier handling at room temperature, flexibility and resistance to wear and tear.
