LY—Standard Grade—WR (High Water-Erosion Resistance Version)
Compared with standard-grade products, the functional LY–standard–WR grade exhibits superior resistance to hot-water erosion. When the formulation is optimized with an AH content of 65%, tensile property degradation remains below 30% after 168 hours of immersion in 70°C hot water, making it suitable for cable processing under special service conditions such as humid environments and frequent water exposure.
