Footwear Grade Polyols

Footwear grade polyols are specially engineered polyurethane raw materials used in manufacturing high-performance shoe sole systems.

These polyols provide excellent flexibility, abrasion resistance, cushioning, durability, and lightweight performance required for modern footwear applications.

They are widely used in sports shoes, leather footwear, sandals, slippers, safety shoes, and industrial workwear footwear systems.

Footwear Grade Polyols

How Footwear Grade Polyols Work

Footwear polyols react with isocyanates to produce polyurethane elastomer systems that form durable and flexible shoe soles.

By controlling hydroxyl value, molecular weight, and functionality, manufacturers can optimize hardness, rebound, comfort, flexibility, and wear resistance.

Different footwear applications require customized formulations ranging from soft flexible slipper soles to highly durable industrial safety shoe systems.
