Product Overview
Premium EPE Solar Encapsulant Film for Flexible Photovoltaics
Our EPE solar encapsulant film is a high-performance encapsulation material developed specifically for flexible solar modules. Made from modified ethylene-propylene copolymer, it offers superior flexibility, low-temperature resistance and weather stability compared to traditional EVA films.
EPE film maintains excellent elasticity and adhesion even in extreme cold environments, making it the ideal choice for thin-film solar panels, flexible photovoltaic modules, building-integrated photovoltaics (BIPV) and portable solar products.
Key Features
- Excellent low-temperature resistance (-40°C to +85°C operating range)
- Superior flexibility and elasticity for curved surfaces
- High light transmittance (>91%) for maximum power generation
- Good anti-PID performance and electrical insulation
- Excellent weather resistance and UV stability
- Strong adhesion to glass, backsheet and flexible substrates
- Customizable softness and cross-linking degree
