    Product Description

    Vinyl acetate (Vinyl acetate) is also known as vinyl acetate, vinyl acetate, ethylene acetic acid, etc., it is an organic compound with the molecular formula C4H6O2, and the relative molecular weight is 86.09. Vinyl acetateIt is a colorless liquid with a sweet ether taste, slightly soluble in water, soluble in cohol,acetone、benzene、chloroform。 that relative density(water=1) 0.93, melting point -100°C, boiling point 72.8°C, flash point -8°C (closed cup).

    There are two main methods for the preparation of vinyl acetate, one is to use it acetylene and acetic acidThe acetylene gas phase method for raw materials, the second is ethylene and acetic acid as raw material ethylene vapor phase direct oxidation method. It is mainly used in the production of polyvinyl alcohol resin and synthetic fibers, and its monomers can be copolymerized to produce adhesives for a variety of purposes, and can also be copolymerized with vinyl chloride, acrylonitrile and other monomers to make polymer synthetic materials with different properties, such as grafting and blocking. It can also be used as an intermediate for oil condensation thickeners, as well as for latex paints, paper coatings, etc.

    FAQ - Technical & Supply Chain

    • Q:

      Does Vinyl Acetate Monomer refer to the reactive liquid monomer or the polymerized resin emulsion?

      A: Vinyl Acetate Monomer is verified under CAS 108-05-4 as the pure, inhibited liquid monomer, distinguishing it from Polyvinyl Acetate (PVAc) or EVA resins to ensure it is suitable for radical polymerization reactions.
    • Q:

      What is the primary role of Vinyl Acetate Monomer in the coatings industry?

      A: Vinyl Acetate Monomer is typically applied as the essential building block for manufacturing polyvinyl acetate latices and copolymers, which serve as the film-forming binders in water-based paints and adhesives.
