Morpholine

Morpholine. Large medical facilities use a central steam supply to provide steam to all sterilizers. Morpholine is amine based additive to steam supply systems to protect metal pipes from corrosion. Morpholine will aggressively attack all amorphous polymers except Radel R.

  1. Morpholine • Large medical facilities use a central steam supply to provide steam to all sterilizers. • Morpholine is amine based additive to steam supply systems to protect metal pipes from corrosion. • Morpholine will aggressively attack all amorphous polymers except Radel R.

  2. MORPHOLINE/AUTOCLAVE STERILIZATION RESISTANCE • 50 PPM Morpholine - Constant Stress - Weighted Cantilever Beam Steam Cycle - 30 Min. @ 270oF (132oC) Applied Stress Total Description (PSI) Cycles Appearance Radel R-5000 1,000 2,000 + Few Tiny Cracks (1,500+) 500 2,000 + Few Tiny Cracks (1,500+) Ultem 1000 1,000 155 Rupture Cracks (50) 500 289 Rupture Cracks (75)

  3. MORPHOLINE/AUTOCLAVE TEST PROCEDURE Front View of Apparatus Appearance of test specimens prior to autoclave exposure. Front View of Apparatus Appearance of test specimens after several autoclave cycles.

  4. FIELD EXPERIENCE • Amoco’s experience shows Radel R Polyphenyl Sulfone can be autoclaved for at least 2000 cycles, without any significant deterioration in properties. • Field reports from medical trays and containers indicate suitability up to 4000 autoclaves.
