摘要： A synthetic cork compound includes a methyl vinyl silicone polymer with a microsphere agent such as soda lime borosilicate in an amount of approximately 5 to 50 weight percent. The microsphere agent gives the compound a low density. The methyl vinyl silicone polymer preferably includes polydimethylvinylsiloxane polymer from about 45 to 90 weight percent and fumed silica from about 5 to 50 weight percent. Preferably, the compound is catalyzed using chloro-platanic acid from about 0.1 to 5 percent. Additional components of the compound include toasted oak dust from about 0.1 to 25 weight percent, ground cork from about 5 to 50 weight percent, a pigment from about 0.1 to 5 weight percent, silicon hydride from about 0.1 to 25 weight percent, and ethynyl cyclohexanol from about 0.05 to 5 weight percent.
