SEPAP MHE

The SEPAP MHE is designed to perform accelerated photoaging of polymers with the aim of understanding the aging mechanisms of polymers exposed outdoors and examining the chemical evolution at a molecular level. Using a mercury vapor lamp, the SEPAP MHE is able to replicate and accelerate the chemical mechanisms responsible for the gradual loss in properties of polymers during their lifetime. The SEPAP MHE is capable of operating at irradiance levels between 90 W/m² and 300 W/m² (290 - 420 nm).
