VAE is basically a polymer dispersions. These dispersions are produced using vinyl acetate monomer (VAM) and Ethylene as a major raw material. Here are the key types of polymer dispersions they offer:
- Vinyl Acetate-Ethylene (VAE) Copolymer Dispersions:
- VAE dispersions combine vinyl acetate and ethylene monomers.
- They offer benefits like flexibility, adhesion, and water resistance.
- Produced without added APEOs (alkylphenol ethoxylates).
- Used in various applications, including adhesives, paints, and coatings.
- PVAc (Polyvinyl Acetate) Homopolymer Dispersions:
- PVAc dispersions are polar, hydrophilic homopolymers.
- They serve as binders and promote strong adhesion and cohesion.
- Commonly used in adhesives, paper coatings, and textiles.
- Dispersions Based on Vinyl Chloride (VC) Co- and Terpolymers:
- These dispersions are based on VC co- and terpolymers.
- Inherent fire retardation due to vinyl chloride polymers.
- Excellent hydrophobicity.
- Used in architectural coatings and construction materials.
Additionally, VAE dispersion can be dried to polymer powders through spray-drying of polymer dispersions. When in contact with water, these dispersible polymer powder grains dissolve and release individual dispersion particles again.
Applications
VAE dispersion offer unique possibilities to assemble food packaging (especially cardboard, but VAE also is able to adhere to plastics). VAE often complies to FDA and EU food packaging laws.
VAE powder is a key ingredient in construcation areas for many cementious adhesives, offering thinbed adhesives, thin floor levelling compounds and tile-over-tile bonding.
