 click chart to close MINBLOC® containing films can enhance plant growth by transmitting greater amounts of photosynthetically active radiation (PAR) to accelerate photosynthesis. MINBLOC is unique in the thermal additives category because its refractive index essentially matches that of the host plastic. This permits higher total light transmission to accelerate crop growth, increase crop yield and improve crop quality. The MINBLOC refractive index also permits loading levels in excess of the traditional 10% limit to optimize thermicity without degrading optical properties. Flow and dispersion properties make MINBLOC a natural choice for highly loaded films.  click to enlarge MINBLOC can also be used to modulate indirect or diffused light in horticultural film. Highly filled thermal films can have as much as 60% haze and still promote accelerated plant growth. By comparison, MINBLOC containing films typically deliver combined direct and indirect light transmittance in excess of 90%. The advantage is uniform plant growth without the shadowing or burn defects characteristic of unfiltered, direct sun exposure.
