Technical & procurement detail
Functional role of sbs (styrene-butadiene-styrene)+
SBS behaves as a vulcanised rubber at service temperature and as a thermoplastic at processing temperature, because its polystyrene domains soften on heating and reform on cooling. That reversibility gives elastic recovery and toughness in compounds and adhesives without a curing step.
Selecting the right grade+
Styrene-butadiene ratio, linear or radial architecture, molecular weight, diblock content and oil extension determine melt flow, elasticity and compatibility with bitumen or tackifiers. End use — hot-melt adhesive, roofing membrane, road binder, footwear sole — dictates the grade.
Documentation and specification+
Properties differ between producers and between grades of the same material. Allzone confirms the applicable grade with the supplier before quoting and shares the technical data sheet and safety data sheet for the exact material offered, so the values you evaluate are the values you receive.
Frequently asked questions
Which SBS grade suits bitumen modification?+
Bitumen modification typically uses specific linear or radial grades selected for elastic recovery and dispersion behaviour in the binder. Share the binder type, target properties and mixing equipment and the matching grade is confirmed with the supplier.
Which grade will I be quoted?+
The grade is set by your specification. Share the target performance, process conditions and any customer or regulatory requirement in the RFQ and the matching grade is confirmed with the supplier before quotation.
What packaging is available?+
Packaging is confirmed with the supplier at quotation for the grade and quantity discussed.
Can you deliver across Ontario and Quebec?+
Yes. LTL and FTL freight is arranged across Ontario, Quebec and Western Canada, with container-direct supply for repeat volumes.
