3M using glass microspheres in greenhouse films
Using microspheres can allow producers to make more amounts of low density and linear low density film with the same amount of resin, application development engineer Fernando Cervantes said at Plastimagen 2016 in Mexico City.
Microspheres also can provide whiteness to films, allowing for the replacement of titanium dioxide, he added. The materials also can spread light over a greater area, which helps plant growth.
Development of microsphere films began last year in the U.S. St, Paul, Minn.-based 3M now is working with film producers on the new application.
