    摘要: The invention provides a method for producing a fluororubber composition that is able to give a crosslinked article that exhibits not only heat resistance, but also excellent mechanical properties at high temperatures. A method for producing a fluororubber composition includes: a step (1-1) of mixing a fluororubber (A) and a carbon black (B) by means of an internal mixer until the maximum temperature reaches 80 to 220° C. so as to obtain an intermediate composition; a step (1-2) of cooling the intermediate composition to a temperature of less than 50° C.; and a step (2-1) of mixing the cooled intermediate composition until the maximum temperature reaches not lower than 10° C. but lower than 80° C. so as to obtain a fluororubber composition.

    摘要: A cellulosic inclusion-thermoplastic composition that includes cellulosic inclusions and a thermoplastic polyolefin that forms a matrix in which the cellulosic inclusions are dispersed. A maleated polymer and a polar thermoplastic polymer resin of a polyamide or polyester are provided to improve adhesion between the cellulosic inclusions and the thermoplastic polyolefin. The polar thermoplastic polymer resin is characterized by a melting temperature greater than that of the thermoplastic polyolefin. The composition as provided has increased break tensile strength relative to a composition devoid of the polar thermoplastic polymer resin but otherwise is unchanged. The break tensile is measured at 23° Celsius and at an elongation rate of 50 millimeters per minute.
