Vinyl acetate copolymer - Names and Identifiers
Vinyl acetate copolymer - Introduction
Vinyl acetate copolymer is a synthetic resin made by copolymerizing Vinyl acetate and other monomers. It has the following properties:
1. Physical properties: Vinyl acetate copolymer is a white to Milky White solid or liquid with high molecular weight and viscosity.
2 chemical properties: it has good solubility, in the solvent can form a transparent solution. It can be compatible with other resins and additives, giving it Adjustable properties.
3. Thermal properties: Vinyl acetate copolymer has good heat resistance and aging resistance, and can maintain its physical and mechanical properties at higher temperatures.
Vinyl acetate copolymer is mainly used in the following fields:
1. Adhesive: Because of its high viscosity and adhesion, it is widely used in the preparation of various adhesives.
2. Coatings and inks: as a thickener and dispersant added to coatings and inks to provide good Coating Performance and particle dispersion.
3. Packaging film and fiber: Vinyl acetate copolymer can be used to prepare all kinds of packaging film and fiber, with certain flexibility and durability.
The methods for preparing Vinyl acetate polymer are generally as follows:
1. Addition polymerization method: vinyl acetate and other monomers are copolymerized under the action of an initiator to generate a copolymer.
2. Indirect copolymerization method: vinyl acetate monomer is synthesized first, and then copolymerized with other monomers.
Regarding safety information, Vinyl acetate copolymer is relatively safe under normal use conditions, but the following matters still need to be noted:
1. Avoid direct contact with skin, eyes and respiratory tract, if there is contact, immediately rinse with water.
2. Avoid inhaling its vapor or dust and ensure that it is used in a well-ventilated area.
3. Avoid sparks or open flames during use to prevent them from burning.
In General, proper use and storage of Vinyl acetate polymer can ensure security and optimal performance. Relevant safety operation regulations shall be observed during operation.
