Product Properties
Excellent Mechanical Properties
The polar ester bonds in the molecule generate strong intermolecular forces. After being formulated into PU materials, it delivers markedly higher tensile strength, tear strength and abrasion resistance compared with polyether polyols. It features a wide adjustable hardness range and good resistance to repeated bending fatigue.
Oil and Non-polar Solvent Resistance
Resistant to mineral oils, greases and fuel oils, making it suitable for oil hoses, oil seals and rollers. It also withstands non-polar solvents, offering prominent advantages in coating and adhesive systems.
