Thermic Film with EVA/EBA, Diffused (TRC DH), manufactured using multilayer co-extrusion systems in different thickness. The correct application of the different raw materials in each layer enhances the film properties.
The film can be Yellow (TRC DN), and also with less diffusion (TRC TH).
Greenhouse film with a duration of 3 Years (*): 3.000ppm Resistant to Sulfur.
Properties and applications
This film has been specially designed to cover tunnels and greenhouses, providing a high resistance to degradation for solar radiation or chemical attacks, due to its special package of U.V. additives.
Disinfectants, pesticides and insecticides must not splash or contaminate the cover of the greenhouse, as it can affect the film duration.
Application: The external layer
The external layer gives the film rigidity and tear resistance, and also has an anti-adherent additive that prevents settlement of dust.
This is the one in contact with the exterior and therefore the first to receive the solar radiation. For that reason, it is provided with an extra package of U.V. additives, which means better protection for the two layers beneath. It gives the film excellent mechanical properties, high transmission of visible light within the greenhouse (luminosity).
Application: The central layer
The central layer, with high EVA content, gives good flexibility, transparency and thermal properties to the film.
Application: The internal layer
The Internal layer provides good light diffusion and it has a special package of co-stabilizers that offers a good performance against different chemical attacks such as pesticides and insecticides used in agriculture.
Great mechanical properties, combining the properties of EVA / EBA copolymers and those of LDPE.
Good resistance to ageing.
High global transmission of visible light (90%) and very good luminosity inside the greenhouse.
Excellent light diffusion effect (55%), avoiding shadows inside the greenhouse and possible burns to the plants.
Optimum thermo-insulating effect (10%) avoiding possible thermic inversions.
External anti-dust layer.
Available with anti-condensation agents (AF).
(*) Minimum duration guaranteed will depend on climatology and radiation of the country or zone where the film is going to be used, and the thickness of this.
