Reliable UV-Resistant Polymer With High Tensile Strength For Cables
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.
