At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the diverse and specialized applications of chemical compounds. Linear Alkylbenzene Sulfonate (LAS) powder, while widely known for its detergent properties, also serves as a highly effective emulsifying agent, particularly in the production of adhesives, such as pressure-sensitive adhesives (PSAs).

The manufacturing of many modern adhesives relies on emulsion polymerization, a process where monomers are dispersed in water as droplets stabilized by emulsifiers. LAS powder, as an anionic surfactant, is exceptionally well-suited for this role. Its amphiphilic nature allows it to orient at the oil-water interface, forming micelles that encapsulate monomer droplets. This stabilization is critical for achieving a uniform particle size distribution of the polymer, which directly impacts the final adhesive properties like tack, adhesion, and cohesion.

The high efficiency of LAS powder as an emulsifier in emulsion polymerization stems from its ability to significantly lower interfacial tension between the monomer and water phases. This leads to smaller, more stable monomer droplets, which in turn facilitates better control over the polymerization reaction and the resulting polymer structure. For manufacturers of pressure-sensitive adhesives, this means the ability to fine-tune the adhesive characteristics to meet specific application requirements, whether for tapes, labels, or protective films.

NINGBO INNO PHARMCHEM CO.,LTD. supplies LAS powder that is manufactured to precise specifications, ensuring optimal performance in emulsion polymerization processes. The purity and particle size of our LAS powder are controlled to guarantee consistent and reliable emulsification, leading to high-quality adhesive products. By using our LAS powder, adhesive manufacturers can benefit from:
