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.

Compatible Products Based on HSP Distance

HSP distance provides an indication of compatibility. It is based upon the “like seeks like” principle. The smaller the distance between ingredients, the more compatible they are predicted to be.
