TOP MANAGERS TAKING QUESTIONS
In the Q&As section, our top managers answer the most interesting and relevant questions from our clients sent to dearcustomer@sibur.ru.
In 2020, SIBUR’s plant in Voronezh launched a new Thermoplastic Elastomers (TPE) line and introduced three licensed grades of styrene-butadiene-styrene: SBS L 7322, 7417 and 7420. The applications of these grades by manufactures of adhesives for furniture, adhesive tapes, sticky labels and hygiene products are discussed below.
SBS-based adhesives have several advantages: they offer an improved performance and feature an optimal proportion of polymer and adhesive content. Moreover, SBS has a strong potential for replacing styrene-isoprene-styrene (SIS) polymers in adhesives for packaging tapes and hygiene products. Compared to SIS, SBS is more frost-resistant and durable; however, high adhesion is harder to achieve.
“With our formulation, we have managed to obtain the target value of the adhesion force,” says Roman Voshchinsky, Chief Expert of the Applications Development Unit (for adhesives). “We offer our customers specific solutions at their request and understand what to do if parameters need to be changed. A good example is our cooperation with hot-melt adhesives manufacturer Ergotek. The range of Ergotek’s products includes a SIS-copolymer-based adhesive for mattress bonding.”
In 2022, it is planned to develop basic formulations for the segments using solvent-based adhesives (used in everyday household adhesives, furniture and automotive industries).
