Polyvinyl Acetate (PVAc) Emulsion, often recognized by its common names such as white glue, PVA glue, or carpenter's glue, stands as a cornerstone in the adhesive industry. This aliphatic, rubbery synthetic polymer is widely acclaimed for its exceptional adhesive properties, particularly on porous materials like wood, paper, and cloth. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing high-quality PVAc emulsions that meet the diverse needs of modern industries, emphasizing reliability and environmental responsibility.

PVAc emulsion is a milky-white liquid prepared through the emulsion polymerization of vinyl acetate monomer (VAc) in a dispersion medium. This process typically involves a protective colloid, traditionally polyvinyl alcohol (PVA), which ensures stability and enhances the mechanical properties of the resulting adhesive. The degree of polymerization for PVAc generally ranges from 100 to 5000 units, contributing to its robust performance. Our PVAc emulsion is characterized by its high adhesion, rapid curing capabilities at room temperature, and an adhesive layer that is colorless and transparent upon drying, ensuring no discoloration of the bonded materials. Furthermore, it is a non-toxic, single-component solution that is easy to apply and clean, offering a remarkably long storage period, making it a highly practical choice for various applications.

Despite its numerous advantages, conventional PVAc emulsions have historically faced challenges regarding water and heat resistance. However, continuous innovation in copolymerization, blending techniques, and the incorporation of advanced additives have significantly mitigated these limitations, broadening the scope of its applicability. For instance, research into utilizing biomaterials like cellulose and starch as stabilizers instead of petroleum-derived components not only improves performance but also aligns with global sustainability efforts by reducing volatile organic compound (VOC) emissions.

The applications of PVAc emulsion are incredibly diverse, spanning across numerous sectors:

Adhesives: It is extensively used as a primary adhesive for woodworking, carton sealing, bookbinding, envelope and wallpaper adhesion, and various handicraft projects. Its strong, flexible bond makes it ideal for paper packaging conversion and as a consolidant for porous building stones, especially sandstone.
Coatings: PVAc copolymers serve as crucial film-forming agents in latex paints for both interior and exterior walls, providing durable and weather-resistant finishes. They are also integral in paper coatings, industrial coatings, wood stains for furniture and parquet varnishes, and protective coatings for metals and plastics.
Construction Materials: In the construction industry, PVAc homopolymers and copolymers are vital in manufacturing joint compounds, caulks, flexible sealants, cement bonding agents, and mastic compounds.
Binders for Nonwovens: It acts as an effective binder in the production of nonwoven fabrics for products such as wipes (baby wipes, personal cleaning wipes), sanitary napkins, filter paper, automotive components, and medical/surgical supplies.
Specialty Applications: Beyond these major uses, PVAc finds niche applications, including as a gum base in chewing gum and as a coating layer for certain cheeses like Gouda.
