Arkema Evatane EVA

Evatane 40-55

High-VA EVA copolymer (VA 40%, MFI 55) engineered for solubility in solvents, compatibility with inks and foam expansion.

Arkema Evatane 40-55 EVA copolymer 25 kg bag

Grade Summary

High VA, High Compatibility

Evatane 40-55 carries 40% vinyl acetate with a melt flow of 55 g/10 min. The high VA level makes the polymer highly soluble in common solvents and highly compatible with polar tackifiers, plasticizers and pigments.

Typical uses include solvent-based adhesives, printing inks, cross-linked foam for footwear and hot melt formulations.

Differentiated Module

High VA Solubility: Solvent Adhesives, Inks & Foam

High vinyl acetate drives solubility and tack in demanding formulations.

At 40% VA, Evatane 40-55 dissolves readily in esters, ketones and aromatics, giving clear, high-solids adhesive and ink solutions. Its polarity also improves wetting of fillers and pigments.

Fast dissolution for solvent-based contact and laminating adhesives.
Strong pigment binding and gloss in printing ink systems.
Excellent expansion and cell uniformity in chemically cross-linked foam.

Processing

Processing Recommendations

Practical guidance for converting Evatane 40-55.

Heat Sensitivity

Low melting point (55 °C) means the resin is heat-sensitive; avoid prolonged high-temperature residence to prevent degradation.

Solvent Systems

Dissolves well in polar solvents; control solids and viscosity for coating and gravure ink lines.

Foam Expansion

Blend with blowing agent and cross-linker; tune cure profile for uniform cell structure.

Adhesive Blending

Combine with tackifier and plasticizer to set tack, set time and flexibility.
