Vespel SP-1 material degradation in space applications

In summary, Vespel SP-1 is a high-performance polymer material commonly used in aerospace and space applications due to its excellent mechanical and thermal properties. It is known for its exceptional resistance to extreme temperatures, chemicals, and wear, making it suitable for use in the harsh conditions of space. However, it is not completely immune to degradation in space, which can be caused by exposure to high levels of radiation and atomic oxygen. To protect Vespel SP-1 from degradation, coatings or additives can be used, and components can be designed to minimize exposure to these elements. If significant degradation occurs, it can compromise the performance and functionality of space components, potentially leading to mission failure. Therefore, careful consideration of Vespel SP-1

Good afternoon,

I'm trying to search only based on bibliography or numerical and theoretical calculations the change of the thermal optical properties, namely the solar absorptivity, of a polyimide-based plastics (VESPEL SP-1) in space conditions (considering radiation, atomized oxygen atoms., etc)

My question is how could I estimate the variation on the thermal optical properties of this materials without doing any experimental test (ageing tests). Also in bibliography I didn't found any model or any empirical correlation...

Thank you in advance,
Ricardo Gomes
