The new product, Saflex PA41, is a second generation product designed specifically for photovoltaic applications and reduces encapsulant thickness by 33% (from 1.14mm to 0.76mm). The formulation of the PVB was modified to incorporate ‘high flow’ characteristics which enable encapsulant thickness to be decreased while ensuring the finished module package continues to meet critical durability and performance requirements.
The new formulation of Saflex PA41 is also less viscous, compared to traditional PVB products, which improves the encapsulant flow around bus bars and other critical components.
To ensure long-term durability, a rigorous testing regimen was developed that included a series of natural and accelerated weathering tests that goes beyond photovoltaic industry standards. Plus, Saflex partnered with module manufacturers to confirm that handling, processing and throughput of PA41 met or exceeded expectations compared to thicker gauge PVB encapsulants. Saflex PA41 also recently passed IEC 61646 certification testing and is UL recognized.
