- loose of characteristics
- etc..
Thanks for your input. I am looking to documents about UV effect on driving belts polyurethane jacket with steel cords inside (looking like the ones used to drive a starter or an alternator in the car)
Compare to other diene elastomers , Polyurethanes show good weathering properties. However the show slight embritlement under sun after years of exposure. It depends on weather conditions (ozone, oxigen sun) and PU typeolyether based slightly more resistant than polyester based
