Application
UV ABSORBER HOSORB-UV3638 is a highly efficient benzoxazinone type UV absorber,
which is distinguished by its superior low volatility and strong & broad range of
UV light absorption together with no color contribution & excellent stabilization
for polymers. It is designed to meet the demanding high temperature requirements
for processing engineering plastics such as Nylon, PC,PET,PBT and PPO. It is also
highly effective in other polymers such as polyamides, polyacetals, polyolefins
fibers, styrenics, elastomers where long term UV light stability is required.
