Greenhouse film PLASTERMIC DH-DN

polyethyleneUV-resistantthermal

Thermic film, with LDPE base, Diffused, in White (H), PLASTERMIC DH, or Yellow (N) PLASTERMIC DN colour and manufactured in multilayer co-extrusion systems and different thickness. Properties and Applications: This film has been designed to cover greenhouses and tunnels. It has a special package of co-stabilisers that offers a good performance against chemical attacks and solar radiation. It contains as well a special package of thermic additives in order to thermo-regulate the cultivated area. These additives provide a barrier against the loss of long wave Infra Red radiation (7-14µ), which is emitted by the earth during the night. This provides as well a very good thermicity, thus avoiding sharp nocturnal and diurnal temperature differentials and the risk of frost which are harmful to the plant. (Thermic inversion). With a high light diffusion, the film eliminates shadows from within the greenhouse and allows an equal distribution of light across the crop, thus increasing yield. Disinfectants, pesticides and insecticides must not splash or contaminate the cover of the greenhouse, as it can affect the film duration. Advantages: - Very good mechanical properties. - High resistance to ageing. - High light diffusion (60%), avoiding shadows inside the greenhouse. - Optimum thermo-isolating effect, avoiding night cooling and risk of frost. - Recommended for those place with high isolation during the day and low temperatures at night.
