Typical usage ratio

• 30–50% of hot melt adhesive mass, tuned according to open time and required bond strength; higher ratios for low-temperature bonding

Downstream process integration

• Dosing into high-shear mixers, followed by extrusion compounding and solidification into pellet or block format for subsequent melting and application

Final product types

• Packaging adhesives for fold cartons, corrugated, bottle labeling, and case/carton sealing
• Industrially compounded hot melt adhesive pellets and blocks

3. Wire and Cable Compound Manufacturing

Cable insulation and sheathing producers employ Ateva 2020 EVA for its electrical insulating properties, flexibility, and capability to accept high loadings of flame retardants without compromising extrusion stability. The resin enters compounding lines where it accepts stabilizer, crosslinking, and flame-retardant packages, directly supporting compliance-driven builds for power, data, and control cables subjected to chemical and UV exposure as well as thermal cycling.

Downstream process integration

• Incorporation into twin-screw or Banbury-type extruders with filler, UV stabilizers, and flame retardant systems, pelletization, and reintroduction in cable extrusion lines

Final product types

• Cable insulation and sheathing for power, instrumentation, and fiber-optic lines
• LSZH insulation compounds and jacketing materials

4. Foam Sheet and Pad Fabrication

Producers of footwear, sports mats, and packaging foams compound this grade of EVA as the primary matrix to achieve fine cell structure, resilience, and cushioning. The resin supports blowing agent and pigment dispersion while providing sufficient melt strength for continuous foaming. The process involves compounding with azodicarbonamide or other blowing agents, crosslinkers, and fillers prior to thermally induced foam expansion and cooling.
