Thermal sheets manufactured by multilayer coextrusion, combining resins from EVA/EBA copolymers with LDPE, LLDPE and metallocene materials. INDASOL CRISTAL has a special combination of stabilizers that protect against UV radiation, making the film highly resistant to degradation from both UV radiation and treatments applied inside greenhouses.
The combination of copolymer resins in its central layers improves the thermal effect of the film.
In addition, this combination of materials, arranged in suitable layers, makes the film a good transmitter of light, minimizing diffusion.
The outer layer prevents dust from adhering, which maintains the high transmission of visible light throughout the service life of the plastic.
This combination of optical properties makes INDASOL CRISTAL film especially suitable for use in areas with low solar radiation or short daylight hours.
- 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.
- Good heat-insulation effect: the effect of the EBA/EVA copolymers creates 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.
