Autoclavable Plastics
Autoclavable Plastics
(OP)
Hello,
I am looking for autoclavable plastics for a water process application. The specific requriements for this material will be:
(1)cost effective
(2)can be autoclaved repeatedly at 121°C/15 psi
(3)biologically compatible
(4)easy to machine and easy to seal with gaskets.
(5)working environment will be groundwater with neutral pH, temperature will be 0-35 degree C.
With preliminary research, I found the following materials which are autoclavable:
Polypropylene (PP), polypropylene copolymer (PPCO), polymethylpentene (PMP), Tefzel® ETFE, and FEP and PFA.
Any suggestions for choosing the right materials from the above list based on the requriements I mentioned? I am not good at materials and any input will be greatly appreciated .
Thanks,
Jen

RE: Autoclavable Plastics
TPX (poly methyl pentene) will do the job but is expensive and in short supply last I heard. The source is Mitsui.
The injection mouldable fluorocarbons should be OK but expensive.
Have you looked at PPO. It is used extensively in hot water meters, but I don't have actual data here. The most common name is Noryl.
Ultem and polysulphone might also be possibilities.

RE: Autoclavable Plastics
Thank you very much for your input. Noryl seems a strong candidate for its low cost as an autoclabable and biocompatible material. Ultem and polysulphone look good too. Thanks again and I really appreciate.
Best,
Jen
