Its unique properties offer broad application prospects in industrial production. This article elaborates on the physical, chemical, mechanical, thermal, electrical, optical, and biodegradable properties of PVAc, aiming to provide references for research and practical applications in related fields.

1. Physical Properties

Polyvinyl acetate is a white or light-yellow solid powder with good flowability and plasticity. Its glass transition temperature (Tg) is approximately 80°C, and its melting point is around 170°C. The density of PVAc is about 1.3 g/cm³, and it exhibits excellent mechanical strength and toughness. Additionally, PVAc has high tensile, compressive, and flexural strengths, making it an ideal engineering material.

2. Chemical Properties

Polyvinyl acetate is a nonpolar polymer with strong corrosion resistance to most chemicals. it is highly soluble in strong acids, strong bases, and certain organic solvents such as alcohols and ketones. Furthermore, PVAc has hygroscopic properties and tends to absorb moisture from the air. Storage and handling should avoid contact with these substances.

3. Mechanical Properties

The mechanical performance of PVAc is reflected in its tensile, compressive, and flexural strengths. These properties vary significantly depending on polymerization methods and processing conditions. Generally, the tensile strength ranges from 150–400 MPa, compressive strength from 10–20 MPa, and flexural strength from 10–30 MPa. Such properties enable diverse industrial applications.

4. Thermal Properties

Key thermal properties of PVAc include its glass transition temperature (~80°C), melting point (~170°C), and thermal stability. At high temperatures, PVAc decomposes into carbon black and water, limiting its use in高温 environments.

5. Electrical Properties

Polyvinyl acetate is an insulating material with low dielectric constant and dielectric loss tangent, suitable for high-frequency applications. It also exhibits good conductivity, allowing its use in conductive films and electrodes.

6. Optical Properties

PVAc demonstrates high transparency and a refractive index of ~1.45, making it suitable for transparent films and optical components. Its optical properties position it well for applications in fiber-optic communication.

7. Biodegradability

Polyvinyl acetate is a biodegradable material with degradation rates influenced by pH, temperature, and microbial activity. In natural environments, it decomposes into harmless substances like carbon dioxide, water, and biomass, classifying it as an eco-friendly material with promising applications.

As a polymer material, PVAc possesses multiple excellent properties, offering broad industrial potential. Further research into its application-specific performance and processing techniques is needed to fully leverage its capabilities.
