Revision as of 11:05, 13 September 2022 by Michel Lamontagne (talk | contribs) (→In situ Production)
Polyester (PET) is an organic material, a polymer plastic that is commonly used as a fiber for cloth production, or a matrix for glass fibers in Fiberglass
In situ Production
Polyesters are polymers (chains) that contain ester groups in their repeating structure. The most common form is polyethylene terephthalate (PET).
- Polyethylene terephthalate is produced from ethylene glycol and dimethyl terephthalate (DMT) (C6H4(CO2CH3)2) or terephthalic acid.
- Ethylene glycol is a primary chemical feedstock and is very likely to be produced on Mars fairly soon.
