High Moisture Permeability TPU Film Suppliers

How resistant is the high moisture permeability TPU film to abrasion, UV exposure, and chemicals?

The high moisture permeability TPU film is generally designed to be highly durable and versatile, but its specific resistance to abrasion, UV exposure, and chemicals can depend on the formulation and additives used. Here's a general overview based on the typical properties of TPU (thermoplastic polyurethane) films:

Abrasion Resistance:
TPU materials are known for their excellent abrasion resistance, making them suitable for applications where wear and tear are concerns, such as in outerwear (jackets, gloves), sports equipment, and military gear. The film’s inherent toughness and flexibility contribute to its ability to withstand physical abrasion, especially when used in environments that require frequent movement or contact with rough surfaces.

Key factors influencing abrasion resistance:
Hardness: TPU films can be produced with varying degrees of hardness, and harder grades typically offer better abrasion resistance.
Thickness: Thicker films often provide greater protection against abrasion, especially in high-contact areas like the elbows or knees of jackets and sports gear.

UV Exposure Resistance:
High moisture permeability TPU film generally offer moderate resistance to UV exposure, but they may degrade over time when exposed to prolonged sunlight or UV rays. UV degradation can cause yellowing, embrittlement, and loss of flexibility, particularly in outdoor gear (jackets, tents, etc.) or products used in sunlight-exposed environments.

Enhancing UV resistance:
UV stabilizers or anti-UV additives can be incorporated into the TPU formulation to improve UV resistance and prevent these issues.
For critical outdoor applications, buyers may request films specifically treated for high UV resistance to ensure longevity and performance in outdoor conditions.

Chemical Resistance:
High moisture permeability TPU film offer good resistance to many common chemicals, making them suitable for applications where exposure to oils, fuels, and certain solvents may occur. However, the film's chemical resistance can vary depending on the specific chemicals and the grade of TPU used.

Resistant to:
Oils and greases: TPU is resistant to oils, which is why it’s used in items like sports equipment and military gear that might come into contact with lubricants or oils.

Water and detergents: TPU is naturally water-resistant and resistant to most water-based cleaning agents.

Less resistant to:
Strong acids and bases: TPU films might show signs of degradation when exposed to harsh chemicals like concentrated acids or alkaline solutions.

Aromatic solvents (e.g., benzene, toluene): Some TPU films can show reduced durability when exposed to strong solvents. This is especially relevant for applications in automotive interiors or industrial settings where chemicals might be used frequently.

Improving chemical resistance:
Some TPU films are specially formulated with chemical-resistant additives to enhance their performance in certain environments.

Summary of Resistance:
Abrasion resistance: High, making it durable for wear-and-tear applications like outerwear and sports gear.

UV exposure resistance: Moderate, but can be enhanced with additives for long-term outdoor use.

Chemical resistance: Good against oils, water, and mild solvents, but less resistant to strong acids, bases, and aromatic solvents.

If you’re looking for specific performance standards related to abrasion, UV, or chemical exposure for particular applications (e.g., military gear, automotive interiors), it’s possible to request custom formulations with enhanced resistance tailored to your needs. Some manufacturers, like Kunshan Red Apple Plastic New Material Co., Ltd., may offer these types of customizations based on the intended application.
