Applications of Arkema Orevac EVA in Industrial Manufacturing

Arkema Orevac EVA, a functionalized ethylene vinyl acetate copolymer with maleic anhydride grafting, finds critical use across several high-value industrial sectors. As the chemical manufacturer, we supply material directly for downstream applications demanding robust adhesion, compatibility, and performance in compounding, lamination, and modification processes.

1. Polyolefin Compounding for Automotive Bumper Systems

Automotive OEMs and compounders utilize this material to enhance adhesion and impact strength in polypropylene-based bumper fascia and energy absorbers.

• Reactive extrusion with glass or talc fillers
• Homogenization ahead of pelletizing and final molding

Final product types

• Bumper fascia
• Grilles
• Under-hood impact modifiers
• Interior trim panels

2. Hot-Melt Adhesives for Industrial and Packaging Laminates

Producers in the adhesive sector select this material to formulate hot-melt adhesives that require strong bonding to polar and non-polar substrates. Its grafted functionality provides enhanced adhesion to treated films, metal foils, and paper stocks, especially in multi-layer packaging systems. The resin maintains flexibility and peel strength after cooling, making it suitable for automated lamination and high-speed packaging lines.

Typical usage ratio

• 15% to 40% in hot-melt adhesive formulation, depending on target viscosity and bond strength

Downstream process integration

• Blended during bulk adhesive compounding and pelletizing
• Melted and metered into high-speed slot-die or roller laminators

Final product types

• Flexible food packaging laminates
• Industrial box and carton laminates
• Textile/foam assembly laminates
• Bookbinding spines

3. Cable Sheathing and Insulation Compounds

Wire and cable manufacturers use our material as a coupling and compatibilizing agent in halogen-free flame-retardant (HFFR) compounds. It enables strong bonding between polyolefin matrices and inorganic flame retardants like ATH or magnesium hydroxide. The result is a flexible, durable sheath that resists cracking and shrinkage during extrusion, vital for power and telecom cable performance under regulatory fire testing.

Industry compliance standards

• IEC 60502-1 (Power cables)
• EN 50363-8 (Polymeric sheath compounds)
• RoHS Directive (2011/65/EU)

Typical usage ratio

• 3% to 7%, adjusted according to the loading level of ATH and the desired mechanical properties

Downstream process integration

• Incorporated during compounding of polyolefin/HFFR masterbatch
• Melt blended ahead of high-shear extrusion for outer sheathing

Final product types

• Low smoke zero halogen cable jackets
• Power cable insulation layers
• Data transmission cables
• Flexible instrument wiring

4. Multilayer Flexible Barrier Films for Food Packaging

Leading film extrusion plants select the maleic anhydride grafted copolymer as a tie-layer in multilayer co-extruded films that combine polyolefin and EVOH or polyamide barrier layers. Its high interfacial activity enables permanent bonding under high-throughput blown or cast film processes. The material maintains optical clarity where required and ensures the lamination withstands product filling, sealing, and transport.
