ALCUDIA® 117TD is a Ni quencher (yellow greenish color), and benzophenone UV masterbatch LDPE based specially designed for the production of films for covering greenhouses. ALCUDIA® 117/TD, apart from the UV stabilizers, contains antiblock and special antioxidant package of additives. This masterbatch, when properly used, provides high solar radiation resistance.

APPLICATIONS
ALCUDIA® 117TD is specially indicated to produce films for greenhouses and tunnels cover. 180 µm thickness films have a lifetime of two continuous agricultural seasons (two winters and one summer) in geographical areas where the maximum solar radiation is 160 kLy.

The recommended melt temperature range is from 190-210 °C. Processing conditions should be optimized for each production line.

ALCUDIA® 117/TD is specially indicated to produce films with high solar radiation resistance for greenhouses and tunnels cover.

Repsol recommends these dosing of ALCUDIA ® 117/TD with LDPE to produce films, for greenhouses in the geographical zones where the maximum solar radiation is 160 kLy:

• 7 % to produce films having a lifetime of two continuous agricultural seasons (two winters and one summer).

• 10% to produce films having a lifetime of two years.

The film duration depends on the quality of the blend. In order to obtain a very good dispersion and homogenization of the additives in the film, the blend must be done under the best conditions.
