    AI Overview
    Aliphatic E-TPU (Expanded Thermoplastic Polyurethane) is a premium, non-yellowing, high-rebound foam material, commonly used in high-performance footwear and UV-resistant applications. It offers superior UV stability, durability, and flexibility compared to aromatic TPUs, making it ideal for clear or brightly colored products exposed to sunlight, such as protective films and specialized shoe midsoles. 
    Key Characteristics and Benefits 
    • Non-Yellowing/UV Resistance: Unlike aromatic TPU, which can break down and turn yellow, aliphatic E-TPU remains clear and color-stable for extended periods, even with constant sun exposure.
    • High Rebound/Energy Return: Known for excellent mechanical properties, it is often favored in high-performance sports, providing high resilience, shock absorption, and high-energy return.
    • Lightweight & Elastic: It maintains a soft texture with high elasticity, ideal for cushioning.
    • Durability & Strength: Resistant to abrasion, chemicals, and hydrolysis, ensuring a long lifespan. 
    Key Applications 
    • Footwear: Used by brands for high-performance shoe midsoles, cushioning, and durable, aesthetic soles.
    • Optical Films/PPF: Used for Clear Paint Protection Films (PPF) on vehicles, screens, and medical devices due to its transparency.
    • Outdoor Equipment: Ideal for products requiring superior weathering resistance. 
    Composition
    Aliphatic TPUs are formulated using aliphatic isocyanates (such as HDI or
    𝐻12
    𝑀𝐷𝐼
    ), which lack the double bonds that lead to yellowing, unlike aromatic types which use MDI. 
    Key manufacturers for these materials include Covestro with their Desmopan® range and Kunsun Polymer Material (Fujian) Co., Ltd.

    Is TPU better than PEBA?
    Standard TPU still works great for daily trainers, but the new ATPU compound was ready to go fast. Lighter, bouncier, and softer than the PEBA offerings that were in rotation, ATPU foams became known for their ability to absorb energy and to also rebound and give that energy back.Dec 16, 2025
