PUR For Shoe Sole | JCT Machinery

As shoe sole material, polyurethane (PUR) has become an indispensable material in modern footwear due to its unique physical properties, such as wear resistance, elasticity, comfort and weather resistance. Both thermoplastic polyurethane (TPU) and thermosetting polyurethane can meet the needs of different types of shoes, especially in sports shoes, casual shoes, work shoes and outdoor shoes.

JCT Machinery have PUR for shoe sole production line turnkey project.

Advantages of PUR for Shoe Sole

1. Excellent Wear Resistance

Polyurethane (PUR) soles have excellent wear resistance and can withstand long-term use without easy wear. They are very suitable for sports shoes and work shoes that often walk or run.

2. Elasticity and Comfort

PUR materials have high elasticity, which means that the shoe sole can provide good cushioning when walking or running, reduce pressure on the feet, and improve comfort.

The flexibility and resilience of TPU soles are very good, making the shoes more comfortable and supportive when walking.

3. Lightweight

The density of PUR materials is low, making the sole material light and suitable for long-term wear without feeling heavy or tired.

4. Oil and Water Resistance

PUR sole has certain oil resistance and water resistance, and can be used in wet or greasy environments. They are suitable for some special working environments, such as kitchens, industrial areas, etc.

5. Anti-aging

PUR materials have strong resistance to UV and oxidation, and can maintain their appearance and performance for a long time. Even under long-term sun exposure and use, the sole is not easy to become brittle or yellow.

6. Good Grip

PUR sole usually has good grip and anti-slip properties, suitable for sports shoes adn outdoor shoes that require strong grip.

7. Environmental Protection

Modern PUR material production pays more attention to environmental protection. Raw materials and processes used meet environmental protection standards. Some PUR materials are even water-based and solvent-free, which reduces the emission of volatile organnic compounds (VOCs).

One of the most important equipments in PUR for shoe sole production line is reactor.

Reactor not only provides the necessary reaction conditions for the synthesis of PUR resin, but also ensures that the final product has excellent performance and meets the requirements of shoe sole, such as wear resistance, elasticity, comfort and durability, through precise temperature control, pressure control and stirring. The design and operation process of reactor directly affects the quality and production efficiency of the sole material. Therefore, the optimization and precision control of the reactor are crucial to the success of the PUR shoe sole production line.
