● Inner layer: black, smooth, thermoplastic rubber (TPR), oil mist resistant ● Outer layer: black, smooth thermoplastic rubber, erosion resistance, wear resistance ● Reinforcement layer: high-strength synthetic core ● Temperature range: -10°C to +60°C ● Meet the medium to heavy duty engineering applications, with a certain strength; However, it does not lose flexibility, has a long life, and is easy to handle.
