I am looking to replace current material which is PVC with a more durable yet still functional material. I will perform a study but want to include the right selection with a winner the first go around.
the product is being used in a "critical environment" and does get sterilized (in an autoclave) and is exposed to various disinfectants/chemicals
the White PVC discolors orange/brown after autoclave, blue us better but still darkens and doesn’t do well with the harsher chemicals.
• the process is extruded
• the material needs to be durometer shore A – 80 to 90 range
• should withstand:
o Minimum # of Cycles to Resist: 20
o Sterilization Temperature –124.0 C +/-0.5 C
o Sterilization Time –40 minutes
o Pre Vacuum level –(psia) 2.7
o Drying Time –20 minutes (2.7 psia)
• Is exposed to the following chemicals:
o Vesphene II (Steris) -1 ounce per gallon
o LPH SE (Steris) -1/2 ounce per gallon
o Process NPD (Steris) -1/2 ounce per gallon
o TBQ (Steris) -1ounce per gallon
o Coverage Plus NPD (Steris) -1/2ounce per gallon
o Spor Klenz Ready to Use (Steris) -Undiluted
o (peracetic acid and hydrogen peroxide solution )
o 5.25% Sodium Hypochlorite (Steris) -5000ppm
o 5.25% Sodium Hypochlorite (Steris) -Undiluted
o 70% IPA / 30% Water –Undiluted
So far I have selected 2 materials for the study with a handful of others as candidates (durometers may be too hard):
• Santoprene 201-80
• Eastman AP007
Please feel free to comment and/or suggest.
