Superior bending durability. (No abnormalities for 1 million bends) The hose is transparent so you can check the transport. After using the hose, it can be incinerated and does not generate toxic gases (hydrogen chloride, sulfur oxide, nitrogen oxide, hydrogen cyanide, ammonia). (Incinerated ash is less than 0.05%); Tube material has excellent abrasion resistance. (under room temperature); Uses: For sending and exhausting equipment, equipment. For transporting and exhausting food machinery For transmission and exhausting in clean rooms and environments where low dust is required. Not suitable for transporting foods or fluids containing oil. This product uses extremely low dust generating materials, but there is a chance of dust generating depending on the usage conditions (temperature, fluid, pressure, etc.), so please check the dust generation in advance. The dehydrating duct cuffs are also easy. Please avoid using or storing it for a long time.
