POE Polymer Overview - Dow POE PV 8660

Under the "dual carbon" policy and the global clean energy wave, the photovoltaic industry is entering a stage of rapid development. However, the aging and cracking of sealing materials, high water and air permeability, and the decline in insulation performance have always been the key problems restricting the lifespan and performance of photovoltaic modules. Especially, once the sealing of the frame and the packaging structure fails, it will not only affect the power generation efficiency, but also may bring potential safety hazards.

01 | Focusing on photovoltaic applications, we specialize in researching sealing pain points

Traditional materials such as EVA and TPO still have shortcomings in terms of weather resistance, structural toughness and sealing durability. Dow POE polymer PV 8660 is precisely a high-performance ethylene-octene copolymer material developed specifically for the demand of photovoltaic sealants, and it has:

✔ Extremely low water vapor transmission rate, significantly delaying water vapor erosion;

✔ 1100% ultra-high elongation rate, maintaining long-term flexible sealing without cracking;

✔ 1E15 Ω.cm volume resistance, significantly enhancing electrical insulation reliability;

✔ Excellent heat aging resistance, UV resistance and weather resistance, suitable for harsh outdoor environments.
