ROMBEST® IR 550

Inorganic infra-red absorber masterbatch with PE as the carrier resin. It maintains higher night temperatures, reduces fuel consumption for heating and also prevents frost and temperature inversion. It absorbs heat emitted from the greenhouse or low-tunnel during the night. Its recommended addition level in LDPE films is 5-15 % depending on film thickness and required "thermic effect". For LDPE/EVA coextruded films, recommended addition level is 2-10 % depending on film thickness, VA content of the film and required "thermic effect".
