Plasticiser loss from plastic or rubber products through
Other polymer systems that use plasticisers include acrylic polymers, polyamides, polyolefins, polyurethanes, certain fluoroplastics, and elastomers. 7 Particularly, plasticisers are commonly used...
materials - Do plasticizers evaporate in space? - Space
Polymers (think plastic cladding on wires) has "plasticizers", which make it elastic instead of brittle. Those are going to evaporate. Nothing made of plastic is going to be able to take tiny shocks after 100 years.

Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Outgassing
Outgassing (sometimes called offgassing, particularly when in reference to indoor air quality) is the release of a gas that was dissolved, trapped, frozen, or absorbed in some material. [1] Outgassing can include sublimation and evaporation (which are phase transitions of a substance into a gas), as well as desorption, seepage from cracks or
Plasticizer - an overview | ScienceDirect Topics
Specialist plasticisers include phosphates for fire retardancy, polymeric plasticisers (low migration) and some newer ‘non-phthalate’ plasticisers such as citrates, benzoate esters, alkyl sulphonic phenyl esters (Mesamoll), di-isononyl cyclohexane-1,2-dicarboxylate (Hexamoll DINCH) and biobased plasticisers (e.g. Grindsted Soft-n-Safe).
- Can polymers be used in space?
- These effects (e.g., radiation, chain scission, and crosslinking) are to be taken into account when developing polymers for various space applications. Polymers could be used to develop superior construction materials that could be fabricated from space in situ resources.
- How does space affect polymers?
- The extreme environment of space poses unique conditions to polymeric materials. These effects (e.g., radiation, chain scission, and crosslinking) are to be taken into account when developing polymers for various space applications.
- What is the evaporation rate of plasticiser?
- Second, the plasticiser evaporation rate from polymer surfaces is similar (on the same order of magnitude) as the rate from their pure liquid state, indicating that the constant plasticiser concentration on the surface is close to that in the pure liquid (100%).
- Are plasticizers internal or external?
- Plasticizers can be either internal or external, where external plasticizer molecules are not attached to polymer chains by primary bonds and can therefore be lost by evaporation, migration or extraction. On the other hand, internal plasticizers are inherently part of the plastic and remain part of the product .
- How do plasticisers leave a polymer?
- Plasticisers, when not chemically attached to polymer chains, can in certain conditions leave the polymer through migration, evaporation or extraction by liquids.
- Which materials are best suited for space environments?
- Of the most investigated materials, there is a convergence on the notion that polymers and composites are best suited for space environments due to their superior performance against vacuum, radiation, elevated temperatures, and so forth , .
