    FDA approved plastic for use in -40C, -40F, with impact toughness

    I am thinking of changing the material to Delrin instead of Hostaform because it has 11kJ/m2 compared to 6kJ/m2 in impact strength at -30C. But I read that homopolymer has more breaking down in alkali which is used in the cleaning but is this an issue at this relatively low temperatures?

Is there something else strange with this material? And thanks for the tips to contact DuPont I will do that but first try to...

    FDA approved plastic for use in -40C, -40F, with impact toughness

    Hello. I am investigating what material to use in a part used in a freezer at -40C. The material now used is an unfilled copolymer POM. What has happened is that it does not have enough impact toughness and chips falls of if the part is "mistreated". So I wish to improve the impact toughness. I...
