Chimassorb® 81 P

Chimassorb® 81 P by BASF is benzophenone which acts as a UV absorber. It imparts good light stability when used in combination with a hindered amine light stabilizer (HALS) of the Chimassorb®, Tinuvin® or Uvinul® range.

• Shows good compatibility with polyolefins and plasticized PVC.
• Protects a number of other polymers against degradation caused by light exposure such as plasticized PVC and rubbers.
• It can also be used in combination with antioxidants and phosphites.
• Suitable for low density and linear low density polyethylene as well as ethylene-vinyl acetate copolymers for agricultural films.
• It can be used as UV barrier to protect the contents of packages for both industrial and consumer applications.
• Particularly suitable for thick films, typically >100 µm and thick sections.
• Its low vapor pressure prevents losses during processing.
• Low migration rates reduce the risk of blooming.
• Also, in combination with HALS it can be used in high density polyethylene molded articles, such as in crates.
• Chimassorb® 81 P recommended dosage is 0.10-0.5% for PE and 0.15-0.5% for LLDPE, LDPE & EVA.
