    Studies on microcellular soles based on natural rubber/polyethylene blends (1999)
    Springer
    Journal of materials science 34 (1999), S. 1493-1495

    Notes: Abstract Microcellular (MC) soles based on NR/polyethylene blends were developed as possible replacements for the conventional NR/HSR soles. The mechanical properties of the soles suggest that 80/20 NR/LDPE blends can be used for light weight good quality soles. 80/20 blends of NR/HDPE are also found to be promising base materials for good quality soles. A part of HSR in a NR/HSR blend was replaced by LDPE and the effect of replacement on the mechanical properties was evaluated. It is found that 70/15/15 NR/HSR/LDPE and 60/20/20 NR/HSR/LDPE based MC soles show better mechanical properties than NR/LDPE based MC soles.

    Notes: A high density polyethylene grade is blended with two selected grades of linear low density polyethylene and the mechanical and rheological properties of the blends are evaluated over the entire composition range. The blends show sufficient compatibility in the solid phase and in the melt and hence they can be advantageously used to capitalize on their useful properties.

    Description / Table of Contents: Ein mit Ruß gefülltes 50/50 NR/SBR-Blend (Naturkautschuk/Styrol-Butadien-Copolymer) wurde unter Verwendung verschiedener konventioneller Vernetzungssysteme, die durch unterschiedliche Schwefel- und Beschleunigeranteile gekennzeichnet sind, vulkanisiert. Die Vulkanisationscharakteristiken und die Eigenschaften der Vulkanisate wurden verglichen. Das Ausmaß und die Qualität der Vernetzungsstellen wurden für jeden Fall durch chemische Testmethoden ermittelt, um sie mit den Vulkanisateigenschaften zu vergleichen.
    Notes: A carbon black filled 50/50 natural rubber (NR)/styrene-butadiene rubber (SBR) blend is vulcanized using several conventional curing systems designed by varying the amounts of sulphur and accelerator. The cure characteristics and the properties of the vulcanizates are compared. The quantity and quality of crosslinks in each case are evaluated by chemical probes to correlate them with the vulcanizate properties.

    Description / Table of Contents: Mischungen von Elastomeren wie Naturkautschuk und Styrol-Butadien-Kautschuk werden bei verschiedenen Temperaturen vulkanisiert und die Behandlungscharakteristika und Vulkanisateigenschaften verglichen. Die optimale Behandlungszeit bei einer bestimmten Vulkanisationstemperatur konnte empirisch durch eine Exponentialbeziehung dieser Temperatur ausgedrückt werden. Die Vernetzungsdichte der Vulkanisate nimmt mit steigender Vulkanisationstemperatur ab. Für eine vorgegebene Mischung gibt es eine bestimmte Vulkanisationstemperatur, bei der die Materialien die besten Eigenschaften für spezifische Anwendungen besitzen.
    Notes: Gum compounds of natural rubber (NR) and styrene-butadiene rubber (SBR) are vulcanized at different temperatures and the cure characteristics and vulcanizate properties are compared. The optimum cure time at a particular vulcanization temperature could be expressed empirically in terms of that temperature using an exponential relation. The crosslink density of the vulcanizates is found to decrease with an increase in the vulcanization temperature. For a given compound there is a particular vulcanization temperature which gives the best compromise of properties for specific applications.

    Notes: Studies conducted on butadiene-acrylonitrile copolymer (NBR)/poly(vinyl chloride) (PVC) blends at different temperatures indicate that an optimum temperature exists for the formation of a particular blend. The mechanical properties of the blends confirm this observation. PVC stabilizer based on magnesium oxide, zinc oxide, and stearic acid was found to be very useful in NBR/PVC blends.

    Description / Table of Contents: Die physikalischen, mechanischen und rheologischen Eigenschaften von schmelzgemischten Blends aus Polyethylen niedriger Dichte (LDPE) und linearem Polyethylen niedriger Dichte (LLDPE) wurden ermittelt. Die Blends verfügen uber die guten mechanischen Eigenschaften von LLDPE und die Verarbeitungseigenschaften von LDPE. Der Einfluß einer Vernetzung mit Dicumylperoxid (1 phr) wurde ebenfalls untersucht. Der Vernetzungsgrad stieg mit zunehmendem LLDPE-Anteil. Während die niechanischen Eigenschaften der vernetzten Blends ziemlich unverändert blieben, verschlechterten sich die durch die Kristallinität des Polymeren kontrollierten Eigenschaften, wie Dichte, Härte und Volumenverlust durch Abrasion.
    Notes: Selected grades of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) were melt-mixed and the physical, mechanical and rheological properties evaluated. The blends were found to combine the good mechanical properties of LLDPE and processing properties of LDPE. The effect of crosslinking the blends with dicumyl peroxide (1 phrParts per hundred rubber) was also investigated. The level of crosslinking increased with increase in LLDPE content. While the mechanical properties of the crosslinked blends were more uniform, the physical properties controlled by the crystallinity of the polymer, such as density, hardness and volume loss on abrasion, decreased on crosslinking.
