And the glass panel molding assembly for a vehicle produced from the aforementioned composition.
摘要:
A method for improving thermal stability of an organopolysiloxane characterized by compounding an organopolysiloxane (A), which was polymerized with participation of an alkali-metal catalyst, with a metal deactivater (B); and an organopolysiloxane mixture composed of an organopolysiloxane (A) characterized by compounding organopolysiloxane (A), which was polymerized with participation of an alkali-metal catalyst, with a metal deactivater (B) used in the amount of 0.02 to 1 part by mass per 10 ppm of the alkali metal contained in component (A).
摘要:
A thermoplastic resin composition comprising (A) a polyolefin-type thermoplastic elastomer or a similar thermoplastic resin, (B) an organopolysiloxane represented by the following average unit formula: R 1 a SiO (4-a)/2 {where R 1 is a univalent hydrocarbon group having 1 to 10 carbon atoms, and "a" is a number in the range of 1.95 to 2.05}, and (C) a metal deactivator; and a product molded from the aforementioned composition. The thermoplastic resin composition is suitable for obtaining molded products that are characterized by their ability to suppress development of defects on the product surfaces after long-term outdoor exposure.
摘要:
An addition-reaction-curable silicone rubber composition comprising: 0.001 to 5 mass % of a metal deactivator and 0.001 to 5 mass % of a curing-retarder selected from an alcohol derivative having carbon-carbon triple bonds, an enyne compound, an alkenyl-containing low-molecular-weight organosiloxane compound, or an alkyne-containing silane; and a molded body produced by curing the aforementioned addition-reaction-curable silicone rubber composition. The addition-reaction-curable silicone rubber composition is capable of producing a molded silicone rubber body, which is obtained with low compression set without resorting to secondary thermal treatment.
摘要:
The present invention provides a silicone-containing thermoplastic fluororesin composition having excellent flame retardance, flexibility and mechanical properties and enabling an obtained crosslinked product to be printed, a molded article comprising the composition, and a process for preparing the silicone-containing thermoplastic fluororesin composition. Specifically, the present invention relates to a silicone-containing thermoplastic fluororesin composition comprising a fluororesin (A) and a silicone rubber (B), wherein the fluororesin (A) comprises a fluorine-containing ethylenic polymer (a) having a carbonyl group-containing end group, and the silicone rubber (B) is crosslinked at least in a part thereof.
