Applications exposed to repeated mechanical stress, abrasion, and elevated temperatures require materials capable of maintaining performance over time. In industrial environments, components are often subjected to continuous movement, dynamic loads, and contact with moisture, oils, or chemical agents. Selecting the right material is therefore essential to ensure durability and reliable operation throughout the product lifecycle.
ETERNALAST® LD4070D is a polycarbonate-based TPU developed for injection and extrusion processes and designed for high-temperature applications. The material combines high mechanical strength with excellent durability, making it suitable for components that must withstand demanding operating conditions.
A key characteristic of ETERNALAST® LD4070D is its ability to perform in challenging environments. Excellent hydrolysis and chemical stability help preserve material integrity when exposed to moisture and various chemical substances. The material/product also offers resistance to oils, and several non-polar solvents, supporting its use across a broad range of industrial sectors.
For applications involving repeated movement and friction, wear resistance becomes particularly important. High dynamic load capacity and excellent wear and abrasion resistance contribute to long-term reliability under continuous mechanical stress. The material also provides high tear strength and favourable compression set behaviour, further supporting demanding end-use requirements.
Typical applications include technical parts, cleaning devices, sporting goods, and chair casters, where durability and consistent performance are essential. Designed for high-temperature applications, ETERNALAST® LD4070D provides a robust combination of mechanical properties, stability, and wear resistance.
