CYASORB CYNERGY SOLUTIONS® A400 is an additive designed to protect against polymer degradation in agricultural applications such as greenhouse and mulch films, solarization films, shade cloths and ground covers. A key difference between CYASORB CYNERGY SOLUTIONS® A400 and A430 is service life. A400 is best suited for applications requiring 2+ year service life. It provides excellent thermal and UV protection to polymers such as PE and EVA, and is resistant to commonly used aggressive pesticides and fumigants. A400 improves thermal stability during film processing and service, and does not interfere with light transmission, thereby supporting enhanced crop yield in greenhouses. A400 is compatible with UV absorbers and mulch pigments.
