Microbe-resistant and hydrolysis-resistant suction hoses and delivery hoses

Our hydrolysis-resistant and microbe-resistant hoses are made of polyester and ether polyurethane. This type of hose with a milky hose wall helps in applications where blockages can easily occur within the hose - for example when vacuuming up muck residues. For applications in which microbe-resistant and/or hydrolysis-resistant hoses are used, they are usually subjected to strong and dynamic movements, such as in road sweeping and suction vehicles for street cleaning. Here, the polyurethane material used scores highly with its good mechanical properties under tensile and compressive loads as well as deformations.

The advantage of the ether polyurethane used by Masterflex in production is that the material is already permanently resistant to microbes and hydrolysis without the need for additional additives and no extra microbicides need to be added. These properties of the ether version of polyurethane are particularly effective for outdoor applications.

Due to its chemical structure, ether polyurethane is resistant to microbes and is the perfect material for hoses that come into contact with earth-like substances during operation and are subject to stress and heavy soiling. These conditions - often in combination with a permanently damp and warm environment - are very hard on normal hoses in outdoor use and cause them to weather and wear quickly. In polyester-based materials, the ester compounds are gradually broken down by the enzymes of microorganisms. However, the polyether polyurethane we use can also be a good alternative for many applications in this area.
