We are 3D printing masks that need to be used by medical staff treating COVID19 patients.
The first link is an overview of the material we are using for masks in general.
The second is the specific product we are making masks out of.
1- To sterilize; can we safely do 120C for 30 minutes without the mask losing shape? What about 70C for 30 minutes? Will it affect integrity and water/air proof "ness"
2 - Should we sterilize in humid air? dry air? again to maintain shape and impermeability
3 - will this be stable with exposure to 1) Vapor H2O2 @ >480 ppm for 30 minutes? 2) 1:9 bleach:water immersion? 3) household disinfectants (google Lysol)
We are making masks from this material and would be happy to recieve insights from people in the field.
