Clariant introduces new polymer to limit hydrolytic dehydration




Clariant is introducing new polymer compounds specially formulated to limit or even eliminate hydrolytic degradation, which is known to affect certain materials commonly used in catheters. The new resins are offered under the MEVOPUR brand name.
“After several years of research and testing, we are pleased to be able to limit the risk of hydrolysis and breakage in these materials, thereby helping device manufacturers improve the reliability of catheters,” said Eric Rohr, Medical & Pharmaceutical Segment Manager, North America.
One of the first indications of chain scission is an increased melt-flow index (MFI).
Tensile strength and elongation properties in standard test bars molded from the test materials were similarly unaffected in MEVOPUR compounds, while the standard material shows significant degradation in these critical properties.
