Compare aliphatics vs. aromatics TPU film

  • click to rate

    The main difference between aliphatic and aromatic TPU film is that aliphatic TPU PPF film is UV-stable and resists yellowing, making it ideal for outdoor and high-clarity applications, while aromatic TPU is less expensive and mechanically stronger but will yellow with UV exposure. Comparison Table

    Property  Aliphatic TPU Film Aromatic TPU Film
    UV Resistance / Yellowing Excellent; is UV-stable and resists yellowing Poor; yellows and degrades with UV exposure/oxidation
    Transparency/Clarity High clarity; often optical grade Typically has a yellowish tint, even when new
    Mechanical Strength Generally lower tensile strength Higher tensile strength and abrasion resistance
    Cost More expensive Less expensive/more cost-effective
    Lifespan (Outdoor) Long-lasting (often 7-10+ year warranties for PPF) Shorter lifespan (yellows within 1-2 years outdoors)

    Key Decision Factors

    • Aliphatic TPU Film: Choose this if UV exposure, color stability, and clarity are critical. It is the standard for premium, long-term outdoor applications.
      • Ideal forAutomotive paint protection film (PPF), high-end medical devices, electronic screen protectors, and architectural films that must remain transparent and clear over time.
    • Aromatic TPU Film: Choose this if cost is a primary concern and the film will be used in applications with minimal or no UV exposure.
      • Ideal for: Indoor industrial uses, economical/short-term protective films, footwear components (soles), and as a base coat in multi-layer coating systems.
