100% Polyuretan: Key material for durability and shape retention. In shoe soles, it serves as a firm foam that doesn't compress and provides long-lasting cushioning. In clothing, it forms the basis of elastic fibers that ensure the garment fits perfectly and doesn't stretch out. PU is also a material for high-quality synthetic leathers, which are strong and easy to maintain. Its versatility gives shoes, clothing, and accessories the necessary strength and longevity.
