When selecting materials for microfluidic applications, ensuring chemical compatibility is key to preserving system performance and integrity. Polyphenylene Sulfide (PPS) is a popular choice due to its excellent mechanical properties, resistance to chemicals, and thermal stability. It is highly resistant to a wide range of acids, bases, salts, and organic solvents, making it ideal for demanding environments.
However, not all chemicals are compatible with PPS, so it’s crucial to understand its chemical compatibility to prevent material degradation and ensure safety. This guide provides a detailed chemical compatibility table for PPS, based on data from IDEX, helping engineers and researchers assess its suitability for different applications.
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 = Little to No Effect
- B = Slight Effect (Minor Discoloration or Corrosion)
- C = Moderate to Severe Effect (Not Recommended)
🚨 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.
