Operation of elastomeric materials in the extreme climatic conditions of the North is a complex and expensive, since not always existing materials can provide the required level of low-temperature characteristics (down to -60 ° C).
Introduction Operation of elastomeric materials in the extreme climatic conditions of the North is a complex and expensive, since not always existing materials can provide the required level of low-temperature characteristics (down to -60 ° C).
Among them are new materials that appeared not long ago in the market of raw materials for rubber products: propylene oxide rubber (Sintez kauchuk, Sterlitamak, Russia) and epichlorohydrin rubber Hydrin T6000 (Zeon, Japan).
Materials based on these rubbers were prepared in “Brabender” plasticizer, then cured in hydraulic press.
