Applications of Arkema Evatane 18-150 EVA in Industrial Manufacturing

Arkema Evatane 18-150 is a high vinyl acetate content ethylene-vinyl acetate copolymer used in multiple industrial sectors, supporting both high-adhesion and flexible end product requirements. As the direct manufacturer, we detail proven downstream uses where this grade addresses specific formulation, process, and regulatory needs.

1. Hot Melt Adhesives for Packaging and Bookbinding

Evatane 18-150 acts as a foundational polymer in hot melt adhesive formulations, delivering high viscosity and superior adhesion to corrugated substrates, paperboard, and coated cardboard. The copolymer ensures consistent melting behavior, tack, and cohesive strength, which is critical for demanding automated packaging lines and precise bookbinding operations where bonding speed and long-term durability are evaluated batch to batch.

• REACH Regulation (EC) No. 1907/2006
• EU Regulation No. 10/2011 (when used for food packaging with migration studies)
• ISO 9001:2015 for adhesive manufacturing QC systems

Typical usage ratio

• 20–40% by formulation weight; further adjusted based on required open time, tack, and substrate porosity

Downstream process integration

• Direct feed into premixing and hot-melt compounding lines; combined in-situ with waxes and tackifiers before extrusion or application coating

Final product types

• Case and carton sealing adhesives
• Book spine glues
• Paper label adhesives
• Laminating adhesives for flexible packaging

2. Wire and Cable Insulation Compounds

Within the wire and cable sector, Evatane 18-150 enhances insulation compound flexibility, electrical properties, and resistance to stress cracking. The high VA content supplies necessary softness and processability, integrating with various fire retardant fillers and stabilizer packages without plasticizer migration. Manufacturers rely on this resin for both jacketing and insulation, especially in low-voltage indoor and communication cables.

Industry compliance standards

• IEC 60502-1 (Power cables with extruded insulation)
• RoHS Directive (2011/65/EU)
• UL 1581 (Electrical wires, cables, and flexible cords)
• EN 50363 (Insulating and sheathing materials for cables)

Typical usage ratio

• 15–35% within compound; loading level varies based on filler content, desired elongation, and target dielectric strength

Downstream process integration

• Dry blending with polyolefins, antioxidants, and compatibilized flame retardants; melt compounded via twin-screw extruder and fed into wire extrusion lines

Final product types

• Low-voltage cable insulation
• Communication and data cable jackets
• Flexible appliance cords
• Specialty automotive wire coverings

3. Photovoltaic Module Encapsulant Sheets

In the renewable energy supply chain, Evatane 18-150 forms the base of encapsulant film formulations, providing elasticity, high transparency, and adhesion to both glass and silicon wafer surfaces. High EVA content supports stable crosslinking and minimal yellowing under UV exposure, characteristics routinely validated during module manufacturer QC. This ensures sustained electrical insulation and weatherability through long service life certifications.

Industry compliance standards

• IEC 61215 (Crystalline silicon module long-term durability)
• UL 1703 (Flat plate PV module safety)
• IEC 61730 (PV module safety qualification)
• RoHS compliance

Typical usage ratio

• Base film comprises 60–80% of total sheet weight; ratio is fine-tuned in line with required gel content and crosslinking speed per crosslink promoter system

Downstream process integration

• Feedstock for film extrusion, with VA-based crosslink agents and UV stabilizers; extrusion into sheet, lamination between glass and cell layer, then thermal crosslinking during module encapsulation

Final product types

• Encapsulant sheets for photovoltaic solar panels
• Protective films in thin-film module stacks
• Photovoltaic edge sealing compounds

4. Flexible Footwear and Foam Products

Evatane 18-150 is widely used in EVA foam compounding for shoe soles, midsoles, and comfort flooring. Its softening and elastic attributes enable fine cell structure and compression set maintenance, even after dynamic stress and aging. It processes efficiently in injection or compression foam molding, accommodating demanding QC specifications linked to wear resistance, shape retention, and odor neutrality in consumer and semi-industrial footwear markets.

Industry compliance standards

• ISO 20344 (Personal protective equipment – Test methods for footwear)
• REACH Annex XVII (restricted substances in consumer articles)
• Prop 65 (California OEHHA compliant for footwear materials)
• EN 71-3 (for foams in children’s footwear and toys)

Typical usage ratio

• Blend content 25–55%; ratio varies with density target, crosslink agent selection, and desired mechanical cushioning performance

Downstream process integration

• Compounding in an internal mixer or Banbury-type kneader with blowing agents, curing agents, and colorants; subsequent sheet extrusion or direct injection into sole molds

Final product types

• Sports and leisure shoe soles
• Work boot midsoles
• Injection molded sandal platforms
• Cushioned anti-fatigue mats

5. Polymer Modification for Polyolefin Films

Converters incorporate Evatane 18-150 to raise sealability, clarity, and stress-crack resistance in PE and PP blown film applications. Its broad compatibility with PE resins enables downgauging and tackle brittle failures in shrink and stretch films, allowing food, secondary, and technical film producers to customize seal performance and cold impact properties specified by large FMCG and industrial packaging clients.

Industry compliance standards

• FDA 21 CFR 177.1350 (Ethylene-vinyl acetate copolymer in contact with food)
• EU 10/2011 on plastic materials and articles intended to come into contact with food
• GFSI/IFS PACsecure (Packaging material safety for food applications)
• ISO 22000 for plant QC managing food packaging films
