SBR-Dichtungen

SBR ist auch als Polystyrol-Butadien-Copolymer bekannt. Die physikalische Struktur, die Verarbeitungsleistung und die Produktleistung von SBR-Dichtungen kommen dem Naturkautschuk sehr nahe. Bestimmte Eigenschaften wie Verschleißfestigkeit, Hitzebeständigkeit, Alterungsbeständigkeit, Vulkanisationsgeschwindigkeit usw. sind dem Naturkautschuk überlegen. Es kann zusammen mit Naturkautschuk und verschiedenen synthetischen Kautschuken verwendet werden. SBR-Dichtungen finden breite Anwendung bei der Herstellung von Reifen, Bändern, Schläuchen, Drähten und Kabeln, medizinischen Geräten und verschiedenen Gummiprodukten. SBR-Kautschuk ist die größte universell einsetzbare synthetische Kautschuksorte und eine der ersten Kautschuksorten, die industriell hergestellt wird.

Weiche Anschlussdichtungen aus Gummi

Gummi weiche Verbindung Dichtungen haben die Vorteile der guten weichen und elastischen Wirkung, so dass die Details in der Dichtung behandelt werden können. Gummi weiche Verbindung nimmt interne nahtlose Hochdruck-Gummi weiche Verbindung, die die Korrosion von korrosiven Medien auf der Innenwand der Gummi weiche Verbindung effektiver in der Pipeline mit hoher Temperaturbeständigkeit, Säure und Lauge Widerstand und Ölbeständigkeit verhindern kann. Verbesserte Nutzungsdauer. Die weiche Gummiverbindung kann die Verbindung und den Ausgleich des Rohrleitungssystems mit gleichem Durchmesser realisieren und den Zweck der gleichzeitigen Verbindung und des Ausgleichs des Rohrleitungssystems in einer Anwendung verwirklichen. Nach der Installation können die Geräusche, die durch die Pipeline-Pumpe und andere Vibrationen erzeugt werden, reduziert werden, und die Vibrationsabsorptionsfähigkeit ist stark.
