Abstract
Procedeul pentru obtinerea unui compound pe baza de cauciuc siliconic, pentru septumuri de cromatografie, caracterizat prin aceea ca se amesteca într-un malaxor elastomer metilvinilsiliconic avînd 0,2% mol unitati metilvinilsiloxanice si masa moleculara 300000...600000, de preferinta 450000, silice de ardere tratata cu dimetilsiloxani ciclici inferiori si cu oxid rosu de fier, în raport în greutate de 100:25...30:20...25, compoundul rezultat fiind omogenizat pe valt supus vulcanizarii la 170...180 degree C, timp de 12h, la un debit de aer de 125 l/kg cauciuc, 1 min.
