Footwear PU Material: Wear-Resistant, Shock-Absorbing For Sneaker,Casual Shoe Soles
Product Description
PU-S85A is a specialized PU material tailored for shoe soles, ideal for sneakers, casual shoes, and light outdoor footwear. Its optimal hardness balances support and flexibility, while high rebound rate enhances shock absorption during walking or running—reducing foot fatigue. With low abrasion index, it resists wear to extend sole lifespan; excellent Grade 4 yellowing resistance keeps soles from discoloring over time. Low compression set ensures long-term shape retention, and compatibility with injection molding suits mass production of sole designs. It meets footwear manufacturers’ demands for durability, comfort, and aesthetic stability.
In addition to its functional benefits, PU S85A offers environmental advantages. It is formulated with eco friendly components, reducing reliance on petroleum based materials and lowering carbon footprint during production. The material’s recyclability further supports sustainable manufacturing practices, aligning with global trends toward greener supply chains. Its non toxic properties also ensure compliance with international safety standards, making it a reliable choice for brands targeting health conscious consumers. By integrating PU S85A, manufacturers can achieve a balance of performance, sustainability, and cost efficiency in footwear production.

The Relationship Between PU and TPU
PU (Polyurethane) is a broad category of polymers made from isocyanates and polyols, encompassing both thermosetting and thermoplastic types. TPU (Thermoplastic Polyurethane) is a specific subset of PU that is thermoplastic. Both share polyurethane as their core component, offering good elasticity, durability, and resistance to wear—widely used in soles, coatings, and accessories. The key difference lies in their processability: most traditional PU (e.g., cast PU) is thermosetting (requiring vulcanization, non-recyclable), while TPU is thermoplastic (moldable at high temperatures, recyclable), adding flexibility for diverse manufacturing needs. In short, TPU is a functional, process-friendly branch of the PU family.
