The company has successfully applied the "Liquid Gold" technology to air spring bellows, endowing them with exceptional tensile fatigue and flex cracking resistance.
Through modification technology, our chloroprene rubber has successfully lowered the brittle point from (minus)-43°C to (minus)-35°C, ensuring reliable operation of air springs under extreme low temperatures of (minus)-40°C. This breakthrough makes us the first company globally to achieve this milestone, while also doubling product lifespan.
