• Encapsulant film comprises 16–22% of module weight; precise layer thickness varies (typically 0.45–0.6 mm per side) depending on module design and lamination pressure

Downstream process integration

• EVA processed via extrusion casting into films; films are layered over photovoltaic cells before lamination in vacuum furnaces at 140–155°C with automated positioning and air evacuation systems

Final product types

• Crystalline silicon solar panels
• Bifacial PV modules
• Thin-film photovoltaic panels
• Building-integrated photovoltaic elements

3. Wire and Cable Compounding

Electrical cable manufacturers deploy the copolymer in sheath and insulation compounds to improve flexibility, flame resistance, and stress-crack resistance in both power and communication cables. The ratio in the formulation depends on compliance with fire safety codes and mechanical properties required for specialized cables such as automotive, underground, or high-frequency signal transmission. Melt blending techniques, combined with on-line extrusion and pelletizing, ensure homogeneous compound distribution and batch consistency.

4. Flexible Packaging Films

Converters in the packaging sector utilize the copolymer for the production of multilayer flexible films used in food and medical packaging, exploiting its sealing capabilities and low-temperature flexibility. The addition level correlates with substrate compatibility and target tensile elongation, with extrusion and lamination lines optimized for thickness uniformity and interlayer adhesion. End products from this application must meet stringent migration and toxicity standards, especially for food and medical device packaging.

Industry compliance standards

• EU Regulation No 10/2011 (Plastics Intended for Food Contact)

Typical usage ratio

• 8–22% by weight in multilayer film structures; the exact proportion depends on film gauge, sealing strength, and coextruded layer ratios

Downstream process integration

• Compound is dry-blended or melt-compounded with LDPE or other resins, then processed via blown film or cast film extrusion prior to surface treatment and lamination

Final product types

• Food vacuum pouches
• Medical device blister packs
• Flexible sachets (pharmaceutical and hygiene products)
• Peelable lidding films

5. Footwear Injection Molding

Manufacturers in the footwear industry incorporate this copolymer into injection-molded compounds for midsoles and outsoles, enabling softness, elasticity, and impact absorption. Suitable for producing lightweight, non-marking sports and leisure shoes, the compound is introduced during the melt blending stage before direct-mold injection. Compliance focuses on consumer safety, VOC emissions, and phthalate restrictions, while the dosage level is tailored for targeted cushioning properties and wear resistance.
