Styrene butadiene latex (SBL) exhibits excellent chemical and mechanical stability, strong adhesiveness, and excellent printability, making it suitable to a wide range of industrial applications in addition to paper coating applications, including use as foam rubber, carpet backing, and adhesives between fiber and rubber, etc.

Chemical Structure

• SBL is a synthetic rubber latex with the principal components being styrene and butadiene.
• It is a water-based emulsion, which makes handling easy and safe, so it is used in a wide range of applications.
• It is a liquid with a milky white appearance and uniform, perfectly spherical particles dispersed stably in water.
• Its glass transition temperature (hardness) and polarity can be adjusted through the composition ratio.
• Particle surface can be a modified type, through the addition of acid monomers and other functional groups, or non-modified type.

Properties

• Low viscosity even when degree of polymerization (molecular weight) is increased
• Low viscosity even when concentration is increased
• Fast drying and film formation
• Easy and safe to handle
