Wacker Vinnapas® EP 1133 Vinyl Acetate Ethylene
Categories: Polymer; Thermoplastic; Ethylene Vinyl Acetate

Material Notes: Product description: VINNAPAS® EP1133 is a carboxylated, higher solids vinyl acetate-ethylene (VAE) copolymer dispersion with a glass transition temperature (Tg) of 0°C. It is a moderately soft binder that performs well for many nonwovens and offers excellent adhesion to various fiber substrates. It also has the ability to be crosslinked.

Properties: VINNAPAS® EP1133 is a unique dispersion combining high solids with carboxyl functionality. The carboxylation provides crosslinking sites and causes the dispersion to thicken in the presence of alkalies. This dispersion exhibits high wet tack and excellent mechanical stability. It has lower plasticizer and solvent thickening response than conventional poly(vinyl alcohol) stabilized dispersions. The dried film exhibits excellent flexibility. The film exhibits slight dry tack, is heat sealable, and can be dissolved with water at a pH of approximately 9.5. VINNAPAS® EP1133 demonstrates a low environmental impact design.

  • It does not use any surfactants or defoamers that contain alkylphenol ethoxylates (APEOs).
  • The total free residual vinyl acetate monomer content is less than 1000 ppm.
Application: VINNAPAS® EP1133 is an excellent base for nonwoven formulators and can be used in a wide variety of applications. The ethylene in the polymer acts as an internal plasticizer which provides flexibility and reduces or eliminates the need for post added plasticizer. VINNAPAS® EP1133 can be applied by a number of different application methods including saturation, spraying, foaming and print bonding. VINNAPAS® EP1133 performs well on various fiber types including cellulose, rayon, fiberglass, and polyester based substrates. This dispersion is especially suited for use in absorbent products and pre-moistened wipes.
