Medium strength silicone sheeting is a versatile elastomer material designed to balance mechanical performance with flexibility, thermal stability, and chemical resistance. It is commonly used when standard silicone lacks the required durability, but high strength silicone is not necessary or cost-effective. This middle-ground option provides adequate tensile strength, tear resistance, and elongation for many demanding environments without the added stiffness or higher cost of high strength formulations.
One of the most common applications for medium strength silicone sheeting is in gasket and sealing products for industrial equipment. In these applications, the material must maintain its shape and elasticity while forming a reliable seal under compression. Medium strength silicone works well in sealing enclosures against dust, moisture, or contaminants, especially in environments where the seal may be repeatedly compressed and released. It offers long service life and consistent performance even when exposed to temperatures ranging from approximately -60°C to +200°C.
Medical and food processing applications also benefit from medium strength silicone sheeting, particularly when FDA or USP Class VI compliance is needed. The material resists bacterial growth, is chemically inert, and can be sterilized without degradation. It can be used for pump diaphragms, transfer tubing, and cushioning components in sensitive environments.
In electronics and automotive industries, medium strength silicone serves as insulation padding, vibration dampening material, or EMI shielding when combined with conductive additives. It has excellent dielectric properties and maintains its integrity under continuous thermal cycling, making it ideal for environments where moderate mechanical stress is combined with high heat or exposure to ozone and UV.
Medium strength silicone sheeting is also used in consumer products and general manufacturing, such as protective pads, weather stripping, and vibration-isolating components. It offers better durability than soft silicone while remaining easier to handle and install than high strength grades. This makes it especially valuable for maintenance teams and OEMs seeking a reliable, general-purpose elastomer with a wide performance envelope.
Select medium strength silicone sheeting when an application requires better physical properties than general purpose silicone but does not demand the extreme tensile or tear strength of high strength silicone. It offers a cost-effective and reliable solution for sealing, insulating, or cushioning across a broad spectrum of industries.
