Collaborative Innovation for Renewable Energy Advancement
Under the Belt and Road Initiative, the partnership between the
EVA/POE photovoltaic film industry and participating nations is
accelerating global renewable energy development. As a pivotal
material in solar module encapsulation, EVA (Ethylene Vinyl
Acetate) and POE (Polyolefin Elastomer) films ensure durability,
efficiency, and longevity of solar panels. This collaboration
bridges technological expertise with emerging markets, fostering
sustainable energy infrastructure and climate resilience.
Why Partner with Belt and Road Nations?
- Abundant Solar Resources: Ideal geographic conditions in Belt and Road countries enable
high-yield solar power generation.
- Growing Energy Demand: Rising electricity needs drive demand for advanced photovoltaic
materials like EVA/POE films.
- Technology Transfer: Advanced extrusion technologies and manufacturing know-how empower
local industries to scale competitively.
- Investment Opportunities: Cross-border infrastructure projects create synergies for joint
ventures and clean energy expansion.
