Polyether Polyol for Insole is a polyether polyol specially used for producing insole materials. It can react with isocyanate to form a soft, light and elastic insole material.
In the polyurethane footwear series, polyurethane materials are widely used because of their comfort, flexibility, durability, and light weight. They are suitable for a variety of footwear applications, ranging from low-density slipper soles to heavy-duty work shoe soles that demand high flexibility and long-lasting performance.

Feature of Polyether Polyol for Insole
Polyether polyols are used in the production of insoles to provide good elasticity, making the insoles comfortable and effective at absorbing impact during walking, which helps relieve pressure on the feet.
Because polyether polyols have a lower density, the finished insoles are lighter, reducing the burden on the feet.
Insoles made from polyether polyols have good wear and pressure resistance. They maintain their shape and elasticity over time, which extends the service life of the insoles.
Some polyether polyol insoles also offer a certain degree of breathability, helping to wick away moisture and keep feet dry.
Antibacterial agents are sometimes added to these insoles to keep them hygienic during long-term use and prevent unpleasant odors.
Polyether polyols come in various types and formulations, allowing adjustment of hardness, density, elasticity, and other properties to meet the needs of different brands and consumers.
They are also environmentally friendly, with some products meeting international environmental standards and capable of being recycled or reused.
Advantages of Polyether Polyol for Insole
Provides excellent comfort, suitable for long-term wear and helps reduce foot fatigue.
Its elasticity and softness effectively absorb walking impact and reduce pressure on joints.
Insoles made with polyether polyols resist wear and pressure well, maintaining elasticity and shape to extend lifespan.
The low density keeps insoles lightweight, avoiding extra burden while wearing.
Meets environmental protection standards, aligning with market demands for eco-friendly products.
