AI Overview
Thermoplastic Polyurethane (TPU) offers excellent resistance to abrasion and environmental aging, typically lasting 7–10 years or longer in various applications. It maintains flexibility in cold temperatures and resists oils, greases, and solvents. Durability can be further improved with UV absorbers, antioxidants, and anti-aging agents.
Key Aspects of TPU Ageing Resistance
- Environmental Stability: TPU is designed to handle harsh conditions, resisting UV light, road debris, and weathering.
- Temperature & Moisture Resistance: TPU maintains flexibility at low temperatures and, while susceptible to hydrolysis, specialized formulations offer improved resistance.
- Chemical Stability: It resists mineral oils, lubricating oils, and animal fats, making it suitable for seals and automotive parts.
- Enhancing Lifespan: To prevent degradation, yellowing, or chemical cross-linking caused by UV light and thermal oxidation, additives such as UV stabilizers are used.
- Performance Metrics: TPU, especially with specific hardness levels like 90A, shows superior aging resistance.
Methods to Improve Ageing Resistance
Applications of Aged-Resistant TPU
- Paint Protection Film (PPF): TPU is used for high-performance, long-lasting automotive coatings, outlasting cheaper materials like TPH.
- Medical Devices: Its non-toxic, hypoallergenic nature allows it to resist bodily fluids (sweat, saliva) over time.
- Industrial Seals & Gaskets: Excellent chemical resistance ensures long-term performance in high-stakes environments.
