The "Thermoplastic Flex Medium-Duty" flexible ducting is a great general all-purpose thermoplastic hose for medium-duty applications. This flexible hose is made from thermoplastic rubber. Thermoplastic rubbers are a class of copolymers that possess both thermoplastic and elastomeric properties, generally made from a mix of plastic and rubber. Thermoplastic rubber products have a successful track record in a wide range of automotive, industrial and commercial applications. These rubber flexible hoses have reduced weight, lower costs, consistent performance, and are recyclable, unlike thermoset rubber compounds. Thermoplastic rubber ducts exhibit durability to extreme temperature and chemical exposure while offering excellent flexibility and abrasion resistance. Our thermoplastic rubber flex ducts are also reinforced with a spring steel wire helix that serves to provide protection and durability for the hose. This flexible hose has a smooth interior that allows minimal friction loss and provides efficient airflow. These medium-duty rubber hoses are ideal for applications involving abrasives, dust, and light materials. The thermoplastic composition also provides excellent moisture, UV, and ozone protection for these industrial ducts. The "Thermoplastic Flex Medium-Duty" industrial ducts are made to operate at both high and low temperatures. This thermoplastic flex ductwork has a temperature range of -40 degrees to +275 degrees Fahrenheit, allowing it to be used in a wide variety of applications. The "Thermoplastic Flex Medium-Duty" rubber hose is made to order in both 25 and 50-foot sections. The medium-duty design of this flexible hose makes this product ideal for applications such as air duct cleaning, dry cleaning, dust collection, pipe organs, paint spray extraction, pollution control, and other general-purpose jobs.
