| Popis: | Films for greenhouse applications were developed with kaolin or Ethyl Vinyl Acetate (EVA) that had the property of transmitting short infrared wavelengths while substantially blocking the transmission of long infrared wavelengths, thus creating a higher degree of "Greenhouse Effect". These films, and controls with other long infrared wavelength absorbers, were evaluated for their mechanical properties (i.e., tensile strength, elongation at break, tear strength and impact strength) and optical properties (haze and total light transmittance) as well as aging resistance. Both kaolin and EVA were satisfac tory as long infrared radiation absorbers and did not significantly affect the mechanical properties or the aging behavior of the agricultural films. Kaolin increased the haze of the films significantly, whereas EVA increased the haze to a smaller extent. |
