Increased lubrication is of interest for a medical application like urine catheters and for medical applications with sliding surfaces like moving syringe gaskets, buttons and gears. At the Wittenburg Group we add lubricants and/or fluor polymers to our Cawiton compounds to decrease the coefficient of friction in order to improve ease of insertion.

We can also change the surface polarity by modifying the polymer matrix or change the surface behaviour from hydrophobic to hydrophilic in order to influence the flow behaviour of medical liquids.

Please contact our engineers to solve your needs for lubricated or surface modified tube/catheter compounds.
