Durable UV-Resistant Polymer For Cables, Engineered With High Tensile Strength For Longevity
Product Description
The DU-85A, meticulously crafted by Dingzhi, stands as a premier anti-UV TPU, renowned for its exceptional and enduring UV resistance capabilities. This high-caliber material boasts a long-term stability in UV resistance, as evidenced by its impressive E△ value remaining less than 1 even after rigorous 48-hour and 168-hour radiation exposure tests, conducted in accordance with the stringent ASTM G154 standards. Beyond its robust UV defense, the DU-85A maintains a consistent hardness throughout its usage, ensuring reliable performance under various conditions. Additionally, it showcases remarkable tensile strength, allowing it to withstand substantial stretching forces without compromising its integrity. Its superior tear strength further enhances its durability, making it highly resistant to tearing or damage. This versatile TPU is compatible with both injection molding and extrusion processes, broadening its applicability in manufacturing. Particularly ideal for use in HFFR (Halogen-Free Flame Retardant) wires and cables, the DU-85A guarantees a durable and steadfast performance, even in environments with prolonged UV exposure, thereby extending the lifespan and reliability of the end products.
The Relationship Between HFFR Wire and UV-resistant TPU Material
The relationship between UV-resistant HFFR wires and polyurethane TPU is rooted in TPU's exceptional material properties that address the stringent requirements of high-performance cable applications. HFFR wires demand materials with robust flame resistance, UV stability, and mechanical durability, all of which are inherent in TPU.
TPU, a thermoplastic elastomer, combines the elasticity of rubber with the processability of plastic. Its chemical structure, particularly polyether or polyester-based formulations, offers inherent resistance to UV degradation. For instance, Dingzhi's DU-90A TPU, tested under ASTM G154, exhibits minimal color change (ΔE<1) after 48-168 hours of UV exposure, ensuring long-term performance in outdoor environments.
In HFFR wires, TPU serves as an ideal sheath material due to its dual role in fire safety and environmental resilience. Its halogen-free formulation meets HFFR's eco-friendly standards while achieving UL94 V-0 flame retardancy through phosphorus-nitrogen-based additives. Additionally, TPU's high tensile strength and tear resistance protect cables from physical stress during installation and use. Its flexibility at low temperatures and resistance to oils and chemicals further extend the lifespan of HFFR wires in harsh conditions.Whether used in automotive wiring, renewable energy systems, or industrial machinery, TPU ensures HFFR wires maintain structural integrity and functionality under prolonged UV exposure, making it an indispensable material for modern cable engineering.
