The main application of BIOSORB® 531 is in combination with a HALS the light stabilization of low density and linear low density polyethylene as well as ethylene-vinyl acetate co-polymers for agricultural films.

The main application of BIOSORB^® 531 is in combination with a HALS the light stabilization of low density and linear low density polyethylene as well as ethylene-vinyl acetate co-polymers for agricultural films. It can be used as well as a UV barrier to protect the contents of packages for both industrial and consumer applications. Also, in combination with HALS, BIOSORB^® 531 can be used in high density polyethylene molded articles, e. g. in crates. BIOSORB^® 531 also protects a number of other polymers against degradation caused by light exposure such as plasticized PVC and rubbers.
