2、Vinyl Acetate

Vinyl acetate (VAM) is a colorless, flammable, volatile liquid with a boiling point of 72–73°C. Practically all use is as a vinyl monomer to produce polyvinyl acetate homopolymers and copolymers.

3、Technical Data Sheet of Vinyl Acetate Monomer (VAM)

VINYLACETATE is a colourless, low-viscous, flammable liquid with an ester-like odour. It is miscible with a number of solvents, but not with water. The vapour is invisible and being heavier than air, it spreads out at floor level. VINYL ACETATE forms explosive mixtures with air.

The molecular weight distribution of vinyl acetate should meet the design requirements and avoid too wide distribution, otherwise it will affect the formability and mechanical properties of the polymer.

Technical Requirements for Vinyl Acetate

Introduction: Vinyl acetate (VAc) is a critical organic chemical raw material widely used in plastics, adhesives, coatings, inks, and binders. With advancements in technology and market demands, higher standards for its quality and performance have emerged. This document provides a detailed exposition of the technical requirements for vinyl acetate.

1. Appearance and Physical Properties Vinyl acetate should be a colorless or pale-yellow transparent liquid with a slight irritating odor. Its density is approximately 1.02 g/cm³, boiling point 150°C, and freezing point -40°C. The viscosity of vinyl acetate varies with temperature and should maintain good fluidity under normal conditions.

2. Chemical Properties Vinyl acetate is stable under normal temperatures and does not readily react with water, alcohols, or acids. under high temperatures, pressure, or specific conditions, it may undergo polymerization or condensation reactions. During storage and handling, contact with such substances should be avoided.

3. Thermal Stability Vinyl acetate exhibits good thermal stability and can be used at elevated temperatures. under certain conditions, decomposition reactions may occur, producing toxic byproducts. In production, temperature control is critical to prevent overheating.

4. Electrical Insulation Vinyl acetate has high electrical insulating properties, making it an excellent insulating material. It can be utilized in electrical equipment as insulating paint, coatings, or other applications.

5. Solvent Resistance Vinyl acetate demonstrates strong resistance to various organic solvents, including alcohols, ethers, ketones, and esters. It can serve as a solvent or additive in coatings, adhesives, and other formulations.

6. Aging Resistance Vinyl acetate possesses moderate aging resistance. prolonged exposure to ultraviolet radiation, heat, or oxygen may lead to oxidation or degradation, reducing its performance. During storage and use, protection from sunlight, moisture, and heat is recommended.

7. Environmental Requirements The production and use of vinyl acetate must comply with environmental regulations and standards to minimize pollution. Safe operations, such as fire and explosion prevention, are mandatory.

8. Quality Control The quality of vinyl acetate directly impacts the performance of related products. Manufacturers must establish rigorous quality management systems, covering raw material procurement, production processes, and product testing to ensure superior quality.

As a vital organic chemical raw material, vinyl acetate requires stringent technical standards. Manufacturers must adhere to relevant norms, continually improving product quality and performance to meet market demands. Consumers should also prioritize product quality and select appropriate grades for specific applications.
