"What makes something UV resistant?
A. UV Stabilized means they have added a stabilizer to the resin to allow it to protect the substance from the long-term degradation from UV light. UV stabilizers work by absorbing or screening out UV radiation and preventing damage. UV Resistant materials by nature resists UV rays and prevent UV degradation."
Two such substances mentioned were carbon black and zinc oxide.
