Multilayer tubing provides a modern, effective, and commonly used solution for a wide range of applications in
medicine, especially if the requirements and production methods of a medical system require the use of several
materials.
We apply over 60 years of experience in the development and manufacturing of high-quality plastic components
ÆÆ Up to four layers can be combined, depending on material requirements
for medical use to every single one of our products, from in-house material formulation and compounding, to
ÆÆ Variable layer thickness distribution based on economics and technical application
