Hygroscopicity and Osmosis in Plastics – Are They the Same?
![]()
Hygroscopicity vs. Osmosis in Plastics – What’s the Difference?
Not all plastics absorb moisture! Hygroscopic plastics (e.g., ABS, PA, PET) pull water into their structure, which can cause defects during processing if not dried properly. Non-hygroscopic plastics (PVC, PE) do not absorb moisture but can act as barriers against osmosis.
💡 Key differences:
✔️ Hygroscopicity – water absorption into plastic granules.
✔️ Osmosis – water passing through a material.
✔️ PVC is not hygroscopic but can reduce osmosis.
