Sotrafa Premium - Model TRC -Thermic Films
Thermic Films with EVA/EBA, and metallocens polymers, Diffused and White colour (TRC DH PREMIUM), manufactured using multilayer co-extrusion systems in different thickness, enhance the properties of the film with the correct application of raw material in each layer. The film can be Yellow (TRC DN PREMIUM), and also with less diffusion (TRC TH PREMIUM). Greenhouse with a duration of 3 Year (*): 5.000ppm 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.
The external layer gives the film rigidity and tear resistance, and also has an anti-adherent addtivie 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)
Advantages:
- 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)
