Product Introduction:
Polyether TPU mainly refers to thermoplastic polyurethane elastomers synthesized with PTMG as the soft segment macromolecular diol. Compared to polyester TPU, polyether TPU exhibits significant advantages in hydrolysis resistance, low-temperature resistance, and mold resistance, making it widely applicable in injection-molded footwear, extruded pipes, films, industrial equipment, and medical fields.
Performance and Applications:
Hydrolysis Resistance: Polyether TPU offers outstanding hydrolysis resistance, maintaining stable performance in humid environments.
Low-Temperature Resistance: Retains good elasticity, flexibility, and other physical properties at low temperatures.
High Elasticity: Polyether TPU exhibits excellent elasticity, accommodating significant deformation without breaking.
Microbial Resistance: This material resists microbial erosion, extending its service life.
Processing Performance: Easy to process using common thermoplastic methods like injection molding and extrusion.
Extrusion and injection molding: Spiral hoses, thick-walled extruded profiles, cable sheaths, etc.
Electronic wiring and cable sheaths: Due to its excellent wear and low-temperature resistance, it is suitable for electronic wiring, power cables, and communication cables.
Automotive parts: Used for car interior components and seals, offering high strength and elasticity.
