The term "silicone" covers a large group of materials, O-rings, gaskets, & custom molded parts in which vinyl-methyl-silicone(VMQ) is often the central ingredient. These compounds can be synthesized with a wide variety of compositions and properties. Silicone seals, O-rings, gaskets, & custom molded parts do not demonstrate the greatest tensile strength or wear resistance, but remain relatively unchanged over a very large temperature range. For these reasons, silicone seals, O-rings, gaskets, & custom molded parts are excellent for extreme temperatures in static applications. However, the low strength and wear resistance of silicone O-rings, gaskets, & custom molded parts causes the seal to fail in many dynamic applications.

TKF Tech carries a range of silicone O-rings, gaskets, & custom molded parts, and we are happy to custom tailor a seal to meet your application requirements! In addition to standard compression molding, silicone can also be injection molded in it's LSR (liquid silicone rubber) form. Silicone seals, O-rings, gaskets, & custom molded parts are popular in applications where extreme temperature fluctuations are common, such as the automotive and aerospace industries. Additionally, many silicone compounds, O-rings, gaskets, & custom molded parts are physiologically neutral making them ideal for the medical and food industries.
