ETFE resin is extruded into a very thin homogenous film. This is a complex process and is done in a controlled factory environment which is dust-free and where a constant temperature is maintained.
F-CLEAN is a specific version of ETFE developed for applications in the horticultural industry as well as in the architectural industry where light transmission is important. Specifically selected fluor granulates are the base of the production process. These give a product with the highest possible level of light transmission.
Throughout the production process additives can be added in order to give the final film specific properties, such as anti-drip characteristics and/or a UV-block.
A thin ETFE film, F-CLEAN® Greenhouse Film is the preferred covering material for horticultural greenhouses as it lets in more light than glass, PE film, polycarbonate and PMMA sheets.
By allowing maximum UV light transmission (up to 94%), F-CLEAN ensures earlier harvest of better quality fruit and vegetables and more colorful flowers.
Low surface energy gives F-CLEAN film non-stick and self-cleaning properties so greenhouses remain clean naturally with rain or snow. And snow will automatically slide off, saving the cost of labor-intensive and expensive snow removal.
No condensation will ever fall onto plants as F-CLEAN has excellent anti-dripping properties.
This highly durable ETFE film has protected greenhouses for more than 30 years without showing signs of deterioration. Grades range in thickness from 60 µm (2.4 mil) to 100 µm (4 mil).
