Applicable Base Polymer Properties

Styrene butadiene rubber high-quality elastomers are often combined with natural rubber to make solvent-based adhesives for masking tapes, labels, cloth tapes, and duct tape. Offering cost-effective tack, shear and peel strength performance where UV resistance is not required, they are manufactured with a consistent molecular weight and viscosity, which enables formulators to achieve a consistent formulation.

Resulting Properties

Linear, non-crosslinked SBR polymers are the technologies of choice when a good balance of adhesion, cohesion and tack is required. The butadiene stiffens as it ages to offset the rubber’s softening over time. These light-colored, low-gel polymers are suitable for general-purpose pressure-sensitive adhesives or as laminating adhesives. The formulations shown above are sprayable adhesives.
