Microbe-resistant and hydrolysis-resistant suction hoses and transport 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 clogging inside the hose is easy - for example, when sucking up manure residues. For applications in which microbe-resistant and/or hydrolysis-resistant hoses are used, they are usually subjected to strong and dynamic movements, as is the case, for example, in street cleaning sweeping and suction vehicles. Here, the polyurethane material used scores with its good mechanical properties under tensile and compressive loads as well as deformation.

The ether polyurethane used by Masterflex in production has the advantage that the material is already permanently resistant to microbes and hydrolysis without any further additives, and no extra microbicides have to be added. In outdoor applications, these properties of the ether variant of polyurethane come into their own particularly well.

Ether polyurethane, which is microbe-resistant due to its chemical structure, is the perfect material for hoses that come into contact with earth-like substances during operation and are subjected to stress and heavy soiling. These conditions - often combined with permanently humid and warm environments - take their toll on normal hoses in outdoor applications, causing 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.
