Product of the ongoing effort to discover new solutions in plasticulture, SOLPLAST has developed a new product that is more durable than the standard materials used to date: INDASOL QU4TRO.

INDASOL QU4TRO is a thermal sheet manufactured by multilayer coextrusion, combining resins from EVA/EBA copolymers with LDPE, LLDPE and metallocene materials. Different resins are combined to make the most of the advantages of each, while at the same time ensuring that the properties of the whole exceed those of each individual material.

The combination of UV stabilizers in its formula boosts its resistance to degradation, making it last longer, even in environments subjected to intensive plant protection treatments.

The product formula includes a combination of additives that form a barrier against IR radiation and also provide good thermal properties that regulate the temperature inside the greenhouse.

Its high degree of diffusion permits the even distribution of radiation inside the greenhouse, reducing shaded areas and promoting uniform crop development.

Main features:

  • Great mechanical strength. The combination of various polymers in different layers provides excellent mechanical strength.
  • High transmission of visible light, which permits the heating of the growing area, favoring plant development throughout the service life of the plastic.
  • Excellent light diffusion, preventing areas of shade inside the greenhouse and reducing irregular plant development by homogenizing light throughout the growing area.
  • Optimal heat-insulation effect:  the combination of its IR additives, along with the effect of the EBA/EVA copolymers, create a barrier against long-wave infrared radiation emitted by the soil at night, preventing sharp temperature drops (especially at night) and eliminating the risk of thermal inversion that could jeopardize plant life.
  • Highly resistant to degradation caused by sunlight and treatments applied inside the greenhouse.
  • Longer-lasting: The greater effectiveness of INDASOL QU4TRO film is evident in post-summer use, during the months of September and October.
