Antioxidant, UV Absorber, Pigments for Agriculture Plastics
Plastics in agriculture also refers to Plasticulture. Plasticulture application includes greenhouse covers, tunnel films, mulch films, silage bags, irrigation pipes, nettings, nonwovens, twines, and substrate/ hydroponic bags. In which greenhouse and mulch film account for almost 70% of the market.
Antioxidant and UV Additives for Agriculture Plastics
Hindered phenolic antioxidant 1076 is recommended for general LDPE film. For plastic agriculture plastics, Anti-oxidising additive varies. One thing we shall bear in mind is choosing antioxidant / UV additives carefully. Cause not only weather, geography, but also other chemicals like pesticide could affect antioxidant performances. High molecular weight hindered amine light stabilizer 783, 944 is recommended in plasticulture, sometimes together with UV absorber 531.
