Problems solved by technology

The flame-retardant thermoplastic elastomers of the prior art have good flame-retardant properties and excellent physical and mechanical properties at room temperature, but poor low-temperature resistance. When the ambient temperature is lower than -10°C, the hardness increases, the elasticity deteriorates, and the strength Reduced, even brittle, affecting use
In the alpine regions of Northeast and Northwest my country, the temperature in severe winter is as low as -40°C. Conveyor belts, cables, auto parts, and shock-absorbing products for rail transit used in the open air must have good cold resistance to ensure normal use. Existing technical thermoplastic elastomers cannot meet these requirements
