Applications of Arkema Evatane 28-40 EVA in Industrial Manufacturing

Arkema Evatane 28-40 EVA, an ethylene-vinyl acetate copolymer with a high vinyl acetate content, is engineered to meet specific industrial demands where flexibility, adhesion, and process stability are critical to downstream manufacturing workflows. Its proven reliability in demanding environments supports consistent quality control and compliance for finished goods across multiple sectors.

1. Hot Melt Adhesive Formulations for Packaging

Evatane 28-40 EVA brings enhanced adhesion and flexibility to hot melt adhesive systems used in carton and case sealing applications. Its high vinyl acetate content delivers secure bonds even at lower temperatures, reducing energy consumption while maintaining high throughput on automated packaging lines. The material ensures excellent machinability and tack properties, enabling adhesive manufacturers to meet stringent packaging performance demands for various substrates, including difficult-to-bond surfaces.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for food packaging)
• Commission Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food
• SQF Code Edition 9 for packaging materials

Typical usage ratio

• 15–40% of total adhesive blend; the ratio depends on adhesive softness, open time, and viscosity requirements. Formulators adjust based on substrate type and line speed.

Downstream process integration

• Added at the compounding stage during powder or pellet blending, then melted and mixed with tackifiers, waxes, and other polymers before extrusion or drum melting.

Final product types

• Hot melt glue sticks, packaging adhesives for corrugated cases, convenience food carton sealing adhesives

2. Photovoltaic Module Encapsulation

The copolymer provides consistent transparency and weathering resistance critical for photovoltaic (PV) module lamination. It offers a high cross-linking potential while preserving elasticity, minimizing the risk of delamination and improving module durability in harsh outdoor conditions. Manufacturers rely on this material for precise process control and to meet technical lifetime guarantees demanded by the solar power industry.

• UL 1703 (Flat-plate photovoltaic modules and panels)
• RoHS Directive (2011/65/EU) on hazardous substances

Typical usage ratio

• 70–80% of encapsulant sheet formulation; the loading adjusts to achieve targeted crosslink density and electrical insulation based on specific PV module requirements.

Downstream process integration

• Granules compounded with UV stabilizers and cross-linking agents, extruded into sheets, then applied as the encapsulant during lamination under vacuum and heat on module assembly lines.

Final product types

• Encapsulant films for crystalline silicon and thin-film PV modules, bifacial panel encapsulants, specialty solar panels for building-integrated photovoltaics (BIPV)

3. Wire and Cable Jacketing Compounds

Our EVA resin boosts flexibility and electrical insulation when compounded into wire and cable jackets. Its high VA content aids flame retardancy and compatibility with filler systems, supporting the manufacture of low-voltage and data transmission cables for demanding automotive, construction, and telecommunication applications where consistent dielectric strength and crack resistance must be demonstrated.

Industry compliance standards

• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• IEC 60502 (Power cables with extruded insulation and their accessories)
• RoHS Directive (2011/65/EU)

Typical usage ratio

• 30–50% by weight in jacketing compound; adjusted for flame retardancy, extrusion speed, and finished jacket thickness as per specific cable type.

Downstream process integration

• Blended and melt-compounded with fire retardants, antioxidants, and processing aids, then pelletized and extruded onto conductor assemblies during insulation and outer sheath application.

Final product types

• Low-voltage electrical cables, data and telecom wire coatings, automotive primary wire jackets, appliance cords

4. Footwear Sole and Midsole Production

This copolymer serves as a primary matrix in injection-molded and foamed shoe soles, contributing to the desired balance of softness, elasticity, and low-temperature flexibility. EVA-based soles produced with this grade achieve lightweight cushioning and shock absorption required for high-performance sports, casual, and safety footwear. Its processing ease accommodates complex multi-layer or colored outsole designs with uniform cell structure and long-term physical stability.

Industry compliance standards

• EN ISO 20345:2022 (Personal protective equipment – Safety footwear)
• REACH Regulation (EC) No 1907/2006 for restricted substances
• GB/T 15107-2013 (China Standard for footwear sole performance)

Typical usage ratio

• 60–80% in midsole foam blends; loading modified based on density, foaming agent, and sole hardness targets for different product lines.

Downstream process integration

• Compound pellets with blowing agents and colorants, then injection-molded or compression-molded into midsoles, outsoles, or full sole units in batch or continuous processes.

Final product types

• Sports shoe midsoles, safety shoe soles, children’s footwear soles, lightweight beach sandals

5. Flexible Film Casting for Agricultural and Industrial Use

The resin supports the manufacture of soft, tear-resistant films suitable for greenhouse, silage, and industrial protective films. Its high clarity and impact resistance safeguard crops and goods during storage and transport, while its compatibility with stabilizer and pigment systems enables stable performance under varying weather and UV exposure. Processors value the precise fusion and drawdown characteristics in wide-width and high-output extrusion lines.

Industry compliance standards

• EN 13206:2017 (Plastic covered greenhouse films)
• ISO 527-3 (Determination of tensile properties of films)
• REACH compliance for additives and pigments

Typical usage ratio

• 20–40% in coextruded film blends; EVA content increases for flexibility and cold resistance in demanding climatic regions.

Downstream process integration

• Pellets dry-blended with LLDPE, masterbatches, or UV stabilizers, then fed into blown film or cast film extrusion lines and converted into specific roll widths for agricultural or industrial users.

Final product types

• Greenhouse films, silage wrap films, industrial shrink and stretch films, flexible membrane liners
