WebIn contrast to other elastomers, the gas permeability of Silicones is very high. In fact, permeability is 30 times than that of natural rubber and 400 times than that of Butyl rubber. Although disadvantaged in seals for gas containers, Silicones find plenty of uses where gas permeability is an advantage i.e. contact lenses, fabric coatings and ... WebJan 31, 2024 · A small percentage of phenyl groups along the chain sufficiently perturbs mobility of the polymer chains and disrupts crystallization, allowing the polymer to remain flexible at very low temperatures; the glass transition temperature of methyl-phenyl-siloxane remains quite negative, with Tg of ca. −25 °C. 2 Crosslinking Mechanism fluid on lungs heart
