Does Acetal Delrin emit fumes when warmed up?
(OP)
I'm using Delrin as a tray to hold small tubes while they cure in an convection oven that is warmed to 50 degrees C and cured over 38 hours. These tubes are sprayed with a chemistry and I'm concerned that the delrin might emit an vapor and contaminate the batch. Is there a concern? Should I pre heat the trays prior to loading them to "season" the delrin?

There is a possibility that Delrin (POM) might emit formaldehyde.
Your idea might be worthwhile.

I would use polyester or even polypropylene at those temperatures. The PP will be a bit flexible but it is quite inert to a very wide range of chemicals. By comparison, polyesters are rigid, inert to almost everything and temperature resistant.
