Silicone liquid rubbers, advantages

In comparison to homogeneous membranes, e.g., of silicon rubber, the SLMs have the advantages of faster membrane diffusion, and easier and wider modification of the liquid phase, which determines the transport mechanism and the selectivity. Further advantages are the low amount of organic solvent and of extractants, low operating costs, easy automation, and high enrichment factors. Dialysis across SLMs has a wide and continuously growing field of application in environmental analysis. Table 3 summarizes some applications. Three modes of separation are used ... 

Applications requiring low adhesion take advantage of the surface properties of the methyl groups (see Mould adhesion and fouling). They include liquid silicone rubber (LSR) used in moulding applications, silicone Release coatings to dispense organic Pressure-sensitive adhesives (PSA) and silicone PSAs. 

Much work continues on the development and introduction of "thenno-plastlc silicone rubbers" and a wide variety of both silicone and silicone-organic block copolymers are being evaluated at this time. As with the liquid silicone rubbers the major fabrication advantage being sought is direct processing by injection molding techniques [20].
