Hydrolysis Kinetics and Lifetime Prediction for Polycarbonate and Polyesters in Solar Energy Applicsumptions and experimental uncertainties, and hydrolysis can be considered unimportant in this solar energy application. Concerns about PET suitability on the basis of its relatively short embrittlement times in the 85 °C/85 % RH damp heat test are unfounded.

A Kinetic Model for Predicting Polymeric Neutron Shieldings Lifetime,on-limited oxidation (DLO): a superficial layer is oxidized whereas the core is not affected. Therefore, to investigate the long-term properties, it is obvious that DLO phenomenon must be taken into account by coupling both oxidation kinetic and oxygen diffusion. In our case, there is a good agreeme

The weight change of LLDPE resulting from thermal aging was studied at constant temperatures ranging from 90 to 170 °C. Three stages were observed including induction, the weight increase, and the weight decrease period. The activation energy for the ind

Test Method Development for Outdoor Exposure and Accelerated Weathering of Vinyl Siding Specimens,nvolved the examination of multiple types of equipment, multiple cycles, and multiple conditions, and comparing the various results to the outdoor exposures. Testing suggested that for this particular material, one method was more suitable than the other. The proposed method was verified with repeat
