Selecting the right material for microfluidic applications requires careful consideration of chemical compatibility to ensure system reliability. PU (Polyurethane) is widely used in various microfluidic applications due to its versatility and resilience.
However, like all materials, PU has limitations and is not compatible with some chemicals. This guide provides a chemical compatibility table for Polyurethane, based on data (at 21°C) from PSI Urethanes, to help users evaluate its suitability for specific needs.
Refer to this table to make informed choices and maintain the efficiency and safety of your system.
The chemical compatibility rating key is as follows:
- A = Excellent chemical compatibility (little to no effect)
- B = Good chemical compatibility (minor to moderate effect)
- C = Fair (moderate effect: not recommended for continuous use)
- D = Severe effect (not recommended for use)
The compatibility ratings provided in these tables are for general guidance only and may not be complete or accurate. They do not address potential contamination or changes in fluid properties due to tubing interaction. We do not guarantee the suitability of any material for specific purposes or the impact of tubing on fluid quality. For critical applications, conduct specific tests or seek expert advice.
