Embossed Solar Encapsulant targets photovoltaic applications.

Press Release Summary:

Thin gauge encapsulant Saflex® PG41 is designed to enhance solar panel throughput for solar module manufacturers that use vacuum encapsulation process. Embossing technology creates micro channels on surface of encapsulant, which facilitate quick removal of air during vacuum encapsulation process, while also reducing visual defects due to air bubbles trapped in encapsulant. Product is less moisture sensitive at edges, even with fluctuating humidity.

Saflex® Introduces Embossed Solar Encapsulant for Photovoltaic Market

Unique encapsulant increases throughput while reducing material usage

ST. LOUIS,-- Saflex, a business unit of Solutia Inc. (NYSE:SOA), announces the launch of a new encapsulant designed specifically to improve solar panel throughput and processing costs for solar module manufacturers that use the vacuum encapsulation process. The product, Saflex® PG41, is a new thin gauge encapsulant that utilizes embossing technology and marks the latest addition to a fast growing PV encapsulant portfolio for Saflex.

Embossing is a mechanical technology that creates 'micro channels' on the surface of the encapsulant. These channels provide a quick and efficient manner to remove air during the vacuum encapsulation process. "It follows the same logic as having treads on a tire," comments Christopher Reed, Business Director for Saflex Photovoltaics. "By embossing the surface, we're providing a means to speed up the vacuum encapsulation process which then increases throughput and ultimately lowers processing costs."

Saflex pioneered embossing technology during the 1990's to improve the vacuum lamination process for manufacturers of automotive windscreens. "Our company has been innovating products for decades for use in automotive and architectural applications. We're now bringing this scale and expertise to the photovoltaic market; embossed technology is yet another example of what can bring to module manufacturers," continues Reed.

Embossing also pulls more air out of the module which improves yields by reducing visual defects due to air bubbles trapped in the encapsulant. This may be especially important for aesthetic applications, including Building Integrated Photovoltaics (BIPV), where optical quality and appearance is a critical product attribute.

Saflex PG41 is a follow up product to the recently launched Saflex PA41 thin gauge PVB encapsulant. Like PA41, material usage of PG41 is reduced by 33% by thinning the encapsulant from 1.14mm to 0.76mm. PG41 is also based on proven 3G PVB chemistry which is proven to be less moisture sensitive especially at the edges, even as environmental conditions, including humidity, fluctuate.

The new Saflex PG41 is the latest addition to a fast-growing portfolio of innovative encapsulants designed specifically for photovoltaic applications. Saflex, a business unit of Solutia, provides solar encapsulants to the solar energy market supported by an 80 year history of manufacturing excellence, global technical support, and the world's largest PVB manufacturing base for glazing applications.
