Adopting a special cold resistant polymer rubber modified formula, optimizing the flexibility of molecular chains, it can maintain good elasticity and toughness in extremely cold environments of -40 ℃, without hardening, cracking, or brittleness at low temperatures. Internally reinforced curtain fabric skeleton is resistant to low temperature fatigue, maintaining stable grip and bending strength in ice, snow, and frozen soil terrain without falling or breaking. It is specially designed for machinery in northern high-altitude regions, snowy forest areas, and polar regions, with all-weather cold resistance and durability.
