Applications

Photovoltaic (Solar) Encapsulation Films:

EP28025 sets the benchmark for solar module encapsulation. Its 28% VA, ultra-low gel, and pure resin guarantee haze-free, transparent films that maximize light transmission and module efficiency. High elongation absorbs thermal stress and prevents cracking or delamination during 25+ years of solar module operation.

Hot Melt Adhesive (HMA) Base Resin:

EP28025 is the preferred base for HMA formulations, offering high polarity for strong substrate adhesion and precise MFI for controlled flow. Used in lamination adhesives, flexible packaging, industrial assembly, and footwear adhesives, it delivers durable bonds and flexible performance.

Wire & Cable Compound:

Used in cable insulation, semi-conductive jackets, and specialty cable compounds, EP28025’s flexibility, low-temperature toughness, and strong adhesion deliver bendable, impact-resistant cables for electrical, automotive, and specialty applications.

Specialty Coating, Lamination & Industrial Applications:

Ideal for thermal lamination films, extrusion coatings, and custom compounding where optical clarity, flexibility, and adhesion are paramount.

Key Application Highlights:

  • Photovoltaic solar encapsulation films (core)
  • Hot melt adhesive base resin (HMA)
  • Wire & cable insulation, semi-conductive jackets
  • Thermal lamination, extrusion coating, specialty compounds

FAQs

Frequently Asked Questions

What is LG Chem EVA EP28025 and why is it designed for photovoltaic encapsulation?
EP28025 is a 28% VA, pure EVA copolymer engineered for solar module encapsulation. Its high VA, ultra-low gel, and additive-free formulation provide crystal-clear, defect-free films, maximizing light transmission and module durability.
Photovoltaic encapsulation films, HMA base resin, wire/cable compounds, thermal lamination films, extrusion coating, and specialty industrial adhesives.
EP28025’s pure resin (no additives), strict gel control, and ultra-high VA set it apart from generic 28% VA EVAs, which may contain slip agents or have higher gel levels—risking haze, delamination, or reduced solar efficiency.
Typical properties: tensile 9.5–11 MPa, elongation 850–950%, Shore A 76, Vicat 45°C, melting point 69°C, ultra-low gel. Process at 160–200°C (extrusion), use conventional blown/cast film lines.
It ensures maximum transparency, eliminates haze, prevents contamination, and guarantees consistent optical/mechanical performance-critical for solar modules’ efficiency and lifespan.
Complies with FDA 21 CFR 177.1350, ISO 13022, IEC 61215/61730, ISO 9001, ISO 14001. For solar or food-contact use, request certificates and confirm with your distributor.
Generic “EVA 28% VA 25 MFI” listings risk brand confusion and inconsistent quality. JITSY ensures you get authentic, South Korean-made EP28025 with full technical data, batch traceability, and regulatory compliance-delivering consistent solar and specialty performance.
