Versatility of Styrene Butadiene Copolymer Resins

Adhesives and sealants based on styrene-butadiene copolymers (SBCs) are both useful and unusual. They have the solubility and thermoplastic nature of polystyrene.


At ambient temperature, they have the toughness and resilience of an elastomer. This characteristic provides styrene-butadiene copolymers adhesives with versatile properties in both adhesive and sealant formulations.

Because of their thermoplastic nature, SBC can be easily formulated into either hot-melt adhesives or solvent solutions. They can even be chemically crosslinked via radiation or the use of reactive end groups.

styrene-butadiene copolymers resins represent a versatile family of resins for adhesive and sealant development. They bond well to many substrates, and their formulation can be easily adjusted to achieve widely varying properties.


This modification usually takes the form of:

·Selection of the appropriate SBC resin of which many are available

·Addition of tackifiers primarily to modify the rheological properties

·Addition of plasticizers, waxes, or oils primarily to modify the application properties

·Addition of other additives such as antioxidants, UV inhibitors, fillers, etc. to provide sufficient stability for the application process and service conditions.


As a result, formulations prepared with styrene-butadiene copolymer resin as base polymer offer a unique combination of properties and have found wide applications in diverse markets such as:


·Building and construction





·Graphic arts

·Tapes and labels

At the service temperatures, the polystyrene segments act as physical crosslinks to connect and lock the elastomeric segments in a three-dimensional network.

At higher temperatures, the end segments will soften and the material can flow under stress.


Since these materials are thermoplastic elastomers they have many performance properties of vulcanized elastomers but can be processed easily on conventional thermoplastic processing equipment.


The low surface energy of Styrene Butadiene Copolymer resins results in good wetting of low surface energy substrates such as polyolefins.


There is no strong chemical interaction with substrates; however, the very good adhesive strength is achieved by the SBC resins ability to conform to the surface and to dissipate energy uniformly throughout the bond area. These factors provide adhesives with high peel strength and toughness.


It is readily apparent why styrene-butadiene copolymers are one of the most popular polymers to use in both pressure-sensitive and non-pressure-sensitive applications.
