The new polymer can reduce the temperature about 7 ° C compared with the normal plastic.
The most widespread remedy to reduce high temperatures in greenhouses plastic cover, It is applying shading coverage based chalks, cal the special paint.
To avoid the application of these protective layers, He has appeared a new polymeric plastic can reduce the temperature inside the greenhouse without changing light levels.
The new polymer for greenhouses 'KoolLite +', produced by the company Hyplast, It has been specially designed to protect crops in countries like Mexico, Kenya, Ethiopia, Vietnam and Saudi Arabia; regions with excess light during warm summers.
This plastic contains a new type pearlescent pigment (small metal), which it has been specially designed to reflect solar radiation near infrared (CIR), in combination with a transmission improved light (BY).
During the last years, Hyplast has launched several tests KoolLite +. "This new plastic can reduce the temperature inside the greenhouse with a difference of 6 to 7 ° C compared to a normal plastic ", said Tom Smedt responsible for Hyplast.
Ensures that the biggest advantage compared to plastic meshes or shading paint application, It is the fact that the plastic allows maximum light diffusion therethrough.
"KoolLite + not only maintains a lower temperature during the day, but also a better diffusion of light towards the cultivation, It is generating a crop stress and more balanced, with better quality and higher yields ".
At night and on cloudy days and colder, the temperature in a greenhouse with KoolLite + is equal to a greenhouse with a normal plastic layer.
"Producers in Mexico already know the results that can be achieved with plastic, today they are implementing large-scale ", said De Smedt, He added that "producers in Saudi Arabia are carrying out tests".
KoolLite + price is greater than the conventional plastic, but according to De Smedt, this plastic saves costs as hedges other supplies for greenhouses. "The shading and cleanliness are expensive operations that depend on the cost of labor in each country".
The KoolLite + is also available with additional features such as anti-drip, opening UV, sulfur resistance, different light stabilizers UV blocker.
