Advantages
1. Excellent shock absorption and cushioning performance, stable resilience after coating.
2. Good cold resistance, applicable for low-temperature use scenarios.
3. Great hydrolysis resistance and soft and smooth material handle.
4. High elasticity, durable and long service life.
5. Stable foaming and molding performance with mature process parameters.
6. Medium hardness formula, balanced toughness and support performance.
Applications
This polyether polyurethane system is widely used for cold-resistant medium-hardness shoe sole materials, marine fender raw materials, and shock absorption mat raw materials. It supports professional foaming and mold forming production for elastic buffer products.
End-use Applications
1. Footwear products: Cold-resistant medium-hardness soles for sports shoes and daily casual shoes.
2. Marine accessories: Marine fender buffer parts for ship anti-collision protection.
3. Shock absorption products: Various shock-absorbing mats, buffer pads and elastic protection components.
