Applications of Hanwha TotalEnergies E282PV EVA in Industrial Manufacturing

Hanwha TotalEnergies E282PV EVA is a specialized ethylene-vinyl acetate copolymer engineered for high-performance industrial applications. As the direct manufacturer, we focus on compliant integration into established downstream use-cases where its molecular design contributes to product durability, processing efficiency, and regulatory compatibility. Below we detail precise application scenarios supported by industry-validated standards, controlled formulation levels, integration stages, and recognized finished goods.

1. Photovoltaic Module Encapsulation

E282PV EVA plays a central role as the encapsulant in photovoltaic (PV) module manufacturing due to its controlled crosslinking and weathering resistance. Our polymer’s characteristics address non-yellowing, transparency retention, and electrical insulation for cell protection through decades of service in harsh environments. The grade demonstrates low gel content and process stability, supporting automation, stable lamination, and reliable module output during mass production.

Industry compliance standards

• IEC 61215: Terrestrial Photovoltaic (PV) Modules - Design Qualification and Type Approval
• UL 1703: Flat-Plate Photovoltaic Modules and Panels
• IEC 62788-1-1: Measurement procedures for encapsulation materials
• RoHS Directive (2011/65/EU) – Restriction of Hazardous Substances

Typical usage ratio

• Typically 400–550 g/m² per lamination (front and back encapsulation layers); weight adjusted according to cell profile, module size, and lamination line design

Downstream process integration

• Extrusion into sheets or films integrated at the lamination step; placed between tempered glass and PV cells, crosslinked under heat and vacuum at 140–155°C for 10–25 minutes, encapsulating sensitive silicon cells prior to framing and junction box installation

Final product types

• Multicrystalline and monocrystalline silicon solar panels
• Thin-film photovoltaic modules
• BIPV (Building-integrated photovoltaic) glass panels

2. Cable and Wire Insulation Compounds

Our EVA copolymer is used in the compounding of low-voltage cable insulation and sheathing materials, adding flexibility and electrical properties required for cable extrusion lines. The controlled vinyl acetate content in the E282PV grade optimizes melt processability and arc-tracking resistance, supporting demanding insulation applications in industrial, telecom, and automotive sectors.

Industry compliance standards

• IEC 60502-1: Power cables with extruded insulation and their accessories
• UL 62: Flexible Cords and Cables
• EN 50363: Insulating, sheathing and covering materials for cables
• REACH (EC 1907/2006) compliance for hazardous substances

Typical usage ratio

• 20–35 wt% as base resin in the insulation compound, with levels adjusted according to mechanical/flexibility targets; masterbatch color or additive adjustments up to 5 wt%

Downstream process integration

• Dry blending with stabilizers and plasticizers, then melt compounding before direct extrusion onto conductor via crosshead dies on continuous production lines at 120–140°C

Final product types

• Flexible low-voltage power and instrument cables
• Fire-retardant signal wires
• Automotive primary wiring sheaths

3. Hot Melt Adhesive Formulations

EVA copolymers with well-defined melt viscosity grades are essential in the production of hot melt adhesive (HMA) systems, including those for packaging and bookbinding industries. Hanwha TotalEnergies E282PV EVA delivers consistent tack and bonding properties, supporting advanced automated lines and application-specific adhesive requirements without compromising surface wetting or adhesive clarity in the end-use.

Industry compliance standards

• FDA 21 CFR 175.105: Adhesives for indirect food contact in food packaging
• EU Framework Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food
• ASTM D3236: Standard Test Method for Apparent Viscosity of Hot Melt Adhesives
• GMP (EU 2023/2006): Materials intended for food contact during packaging production

Typical usage ratio

• 30–55 wt% in HMA base formulation; precise ratio dependent on adhesion strength, viscosity, and specific substrate application, with tackifiers and waxes making up balance

Downstream process integration

• Added as primary resin in formulation blending tanks, then homogenized with waxes and resins at 150–170°C prior to block, pellet, or stick molding for downstream adhesive application machines

Final product types

• Hot melt glue sticks for packaging lines
• Bookbinding adhesives
• Carton sealing and labeling adhesives

4. Solar Panel Backsheet Components

E282PV EVA is formulated into solar module backsheets, where it functions as the bonding and moisture barrier intermediate layer between electrical insulation foils and other protective films. The material resists hydrolysis and ensures layer adhesion stability under outdoor exposure, supporting long service life of the panel and compliance with internationally recognized module reliability standards.

Industry compliance standards

• IEC 61730: PV Module Safety Qualification
• UL 94: Flammability of Plastic Materials for Parts in Devices and Appliances
• EN 50548: Junction boxes for PV modules
• TUV Rheinland 2 PfG 1169: Qualification of backsheets for PV modules

Typical usage ratio

• Plays role as 20–35% of total backsheet film multilayer mass; adjusted per adhesion and mechanical durability after layer lamination and environmental stress testing

Downstream process integration

• Co-extruded or laminated as the core adhesive/sealant layer between PET and fluoropolymer films, followed by calendar rolling and precision slitting to custom backsheet dimensions

Final product types

• Triple-layer PV module backsheets (PET/EVA/fluoropolymer)
• Double-layer electrical insulation films for solar modules

5. Film and Sheet for Greenhouse Coverings

E282PV EVA is widely incorporated in agricultural film manufacturing to improve light transmission, flexibility, and resistance to extreme climates. Formulators select this grade for its optical clarity and ability to maintain mechanical integrity under UV and humidity cycling, ensuring greenhouse films meet regional agricultural demands and long-term deployment cycles.
