Chimassorb® 81 FL

Chimassorb® 81 FL by BASF is a benzophenone grade that acts as a UV absorber. Suitable for low-density and linear low-density polyethylene and polyethylene-vinyl acetate copolymers for agricultural films.

• Imparts good light stability when used in combination with hindered amine light stabilizer (HALS) of Chimassorb®, Tinuvin® or Uvinul® range.
• Protects other polymers against degradation caused by light exposure.
• Shows good compatibility with polyolefins and plasticized PVC.
• It can also be used in combination with antioxidants, phosphites and other light stabilizers.
• It can be used as a UV barrier to protect the contents of packages for both industrial and consumer applications.
• 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.
• It can be used in high-density polyethylene molded articles like crates when used in the combination with HALS.
• The recommended dosage of Chimassorb® 81 FL is 0.10-0.5% for PE and 0.15-0.5 % for LLDPE, LDPE and EVA.
