ETERNALAST LD4075A is a polycarbonate-based TPU (thermoplastic polyurethane) designed for demanding high performance applications. This granulated material, tailored for injection molding, combines superior mechanical strength, exceptional durability, and outstanding abrasion resistance. It is particularly suitable for producing technical components, cleaning devices, technical films, pneumatic tubes, sporting goods, and chair casters, delivering excellent surface finishes and long-lasting performance.
One of the standout features of ETERNALAST LD4075A is its remarkable stability against hydrolysis and chemicals, alongside wear resistance, and compatibility with oils, greases, and various nonpolar solvents. Its mechanical properties include a Shore A hardness of 75, a tensile strength of 42 MPa, and an elongation at break of 454%.
Proper material preparation is critical to achieving optimal performance. As the TPU is hygroscopic, it is essential to dry it to a residual moisture content of ≤ 0.03% using a dry air dryer. After processing, in injection applications, annealing at 105 ºC for 16-24 hours is recommended to relieve residual stresses and maximize crystallinity, ensuring enhanced performance and longevity.
ETERNALAST LD4075A is available in 25 kg bags and commercial samples, making it accessible for various industrial applications. This TPU is ideal for sectors requiring high-performance materials that can withstand extreme conditions while delivering reliable results.
