PTMO (polytetramethylene oxide) is a synthetic elastomeric polyether polymer known for its exceptional flexibility and resilience, making it suitable for applications requiring large deformations and recovery. It is commonly used in sealing applications, flexible tubing, and vibration-damping components across automotive, industrial equipment, and consumer product industries, where its combination of low-temperature flexibility and chemical resistance provides advantages over rigid plastics and natural rubbers. Engineers select PTMO when applications demand high elongation capacity paired with moderate structural stiffness and resistance to ozone and weathering.
