Silicone Rubber Sheeting

Silicone Rubber Sheeting

Silicone rubber sheeting (SI) is a kind of synthetic elastomer composed of silicon, carbon, hydrogen, and oxygen. The material is very flexible across a wide temperature range (-60°C to +200°C), has good releasing qualities, and functions extraordinarily well when subjected to ozone, weathering, and UV radiation. It has a strong compression set, is moisture resistant, and is a superb electrical insulator. The elastomer is also biocompatible, although it is not suited for usage with acids, ketones, or petrochemicals, and it has low wear and tear resistance.
Because of the aforementioned properties, silicone rubber sheeting is employed in a wide variety of applications. It is frequently used to make gaskets for usage in high-temperature conditions, as well as seals for electrical devices. Because of its inertness and compliance with FDA food contact requirements, the elastomer may also be used as a liner in prosthesis and is a popular alternative in the food, drink, and pharmaceutical sectors.
