Applications of Arkema Evatane 1020 VN 5 EVA in Industrial Manufacturing

Arkema Evatane 1020 VN 5, an ethylene-vinyl acetate copolymer (EVA), plays a key role in critical downstream industries where its specific polymer architecture, vinyl acetate content, and melt flow rate directly align with demanding technical requirements. Below, explore the optimal industrial applications fully grounded in its real-world use, spanning from adhesive manufacturing to cable compounding, photovoltaic encapsulation, and flexible packaging films. Each section details exact compliance demands, formulation ranges, processing touchpoints, and targeted end products.

1. Hot Melt Adhesives for Packaging and Bookbinding

Evatane 1020 VN 5 is integral to the formulation of hot melt adhesives designed for automated packaging lines and bookbinding operations, valued for its medium flow and high vinyl acetate content. The polymer enables the synthesis of adhesives displaying immediate bond strength, controlled open time, and resistance to low-temperature brittleness required in high-speed carton closing, labelling, perfect binding, and magazine spine gluing. Integrators rely on its stable rheology during hot melt extrusion, which ensures consistent application weight and minimal adhesive stringing.

Industry compliance standards

Typical usage ratio

• 20-40% by weight in hot melt adhesive base—final ratio depends on targeted softening point and tack, adjusted according to resin, wax, and plasticizer components in the adhesive blend

Downstream process integration

• Directly fed into hot melt mixers or twin-screw extruders with tackifying resins, waxes, antioxidants; compounded at 120-170°C; pumped into block molding or pelletizing lines before supply to adhesive application units

Final product types

• Edge glues for bookbinding and magazine spine adhesives
• Hot melt case and tray sealing applications in food and beverage industries

2. Wire and Cable Compounds: Insulation and Sheathing

Arkema’s Evatane 1020 VN 5 enhances the flexibility and electrical insulation of low-voltage wire and cable jacketing materials. Its use in compounds enables precise tuning of physical and dielectric properties required for safety cables, power conductors, and automotive wiring. The copolymer disperses easily with mineral fillers and flame retardants, contributing to abrasion resistance and stress crack prevention, while facilitating smooth extrusion through cable sheathing lines.

Industry compliance standards

• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• RoHS Directive 2011/65/EU (Restriction of Hazardous Substances)
• IEC 60245 & 60332 (Rubber insulated cables and fire performance test)

Typical usage ratio

• 10-35% by weight in compound, with adjustments based on cable diameter and performance targets, balancing EVA with polyethylene, crosslinking agents, and flame retardant fillers like ATH

Downstream process integration

• Blended in Banbury mixers or continuous compounding extruders with base polymers and additives; pelletized and supplied to wire drawing and extrusion lines where melt processing coats or extrudes the cable’s insulation or sheath at 160-200°C

Final product types

• Low-voltage power cable insulation
• Flexible appliance cords and automotive wiring sheath
• Fire-resistant building wires

3. Photovoltaic (PV) Module Encapsulation

Leading PV module manufacturers use Evatane 1020 VN 5 as a primary encapsulant resin, owing to its transparency, UV resistance, and compatibility with silane crosslinking agents. These features assure long-term adhesion and electrical insulation of solar cell assemblies. The resin’s tailored melt properties support bubble-free film casting and rapid lamination in vacuum lines, securing PV module durability under thermal cycling and weather exposure.

Industry compliance standards

• IEC 61215 (Crystalline silicon terrestrial PV modules design qualification)
• UL 1703 (Flat-Plate Photovoltaic Modules and Panels)
• TÜV Rheinland 2 PfG 1169/08.2007 (Requirements for PV encapsulation films)
• ISO 9001:2015 for module manufacture process control

Typical usage ratio

• 60-80% of film formulation by weight, based on target film thickness (typically 400-600 microns), with minor amounts of photostabilizers and crosslinking promoters as functional additives

Downstream process integration

• Processed in extrusion lines to cast EVA films; films then laminated in encapsulation stacks over PV cells in vacuum laminators at 145-155°C, where in-situ crosslinking occurs during module assembly

Final product types

• Photovoltaic module encapsulant sheets (PV panels for rooftop and utility scale installations)
• BIPV (Building Integrated Photovoltaics) glass-laminate films

4. Flexible Packaging Films: Food and Consumer Goods

Converters incorporate Evatane 1020 VN 5 in multilayer coextruded film formulations for its ability to impart flexibility, cold seal adhesion, and heat sealing at reduced temperatures. The copolymer’s moderate MFI balances mechanical integrity with film processability, optimizing output of stretch films, barrier packaging, and soft lamination layers for food, personal care, or medical items.

• GMP Regulation (EC) No 2023/2006 (Manufacturing practice for food packaging)

Typical usage ratio

• 10-25% by weight in multilayer film blends—dose depends on desired elasticity, seal performance, and film gauge; typically blended with LDPE, LLDPE, and barrier resins

Downstream process integration

• Compounded and extruded through blown or cast film lines; forms middle or sealing layers in 3- to 7-layer film constructions; film rolls are converted into finished bags, wraps, or lamination feedstock

Final product types

• Flexible food packaging films (cheese, bakery, confectionery wraps)
