Silicone Rubber Gaskets

Silicone is the general name for a family of polymers that includes any synthetic compound consisting of repeating units of siloxane (from which the material’s alternate name, polysiloxane, derives). Siloxane is best described as a chain of alternating silicon and oxygen atoms; carbon and/or hydrogen are frequent additives.

Why Silicone Rubber Gaskets?

Silicone Rubber Gaskets are High-Performance Mechanical Seals With a High Resistance to Extreme Temperature. There is little or no effect on the silicone rubber material at temperatures between -60°F to +400°F. It also has exceptional UV and ozone properties which makes them suitable for outdoor applications.

Being an inert material, silicone generally does not react to the majority of chemicals and other fluids like acetic acids, detergents, alcohol and salt water making it popular for use in medical and industrial applications. Silicone is a very clean rubber with low odor and taste and it is generally non-reactive and stable.

Silicone Rubber Seals

Silicone gaskets are used to prevent leaks between different substrate sections in a wide range of applications including for high temperature, food grade (fda), high strength, high purity, fire retardant and thermally conductive emi/rfi applications. Here are some additional benefits of choosing Silicone Rubber Seals:
High Strength, High Temperature Gaskets

These gaskets are engineered to withstand extreme temperatures while offering excellent shock-absorbing properties. Their robust design ensures a long-lasting performance, making them ideal for demanding applications.

High Purity, High Temperature Gaskets

Our gaskets are crafted with high-purity materials, meeting USP Class VI standards. This ensures that they are suitable for critical applications where purity is a top priority, even in high-temperature environments.

EMI/RFI Shielding, High Temperature Gaskets
These gaskets serve as effective shields against electromagnetic interference (EMI) and radiofrequency interference (RFI) while enduring high temperatures. They conduct electricity to safeguard sensitive equipment from harmful static charges.
Fire-Retardant, High Temperature Gaskets

Offering a robust defense against fire and smoke, these gaskets meet stringent standards such as FAR 25.856 and UL94VO. They are a crucial component in fire-resistant applications, ensuring safety and compliance.

Fabric Reinforced, High Temperature Gaskets
We reinforce these gaskets with fiberglass cloth, enhancing their strength and resilience against high stress and flexing. This makes them a reliable choice for applications that demand durability and flexibility.
Criss-Cross Surface
Our gaskets feature a criss-cross surface pattern, providing superior grip and sealing properties. This innovative design ensures a secure and effective seal, even in challenging conditions.

Manufactured from Continuous Rolls or Sheets of Rubber

Alpha die cutting’s solid silicone gasket products are manufactured by die cutting flat parts from continuous rolls or sheets of silicone rubber. So that we provide the customer with the best combination of price, quality and delivery, we source from 3 different silicone rubber suppliers. We source high temperature silicone rubber material to make gaskets that are food grade (FDA), to MIL spec and AMS standards. We manufacture flat standard gasket and washer sizes, as well as custom sizes. Alpha Die Cutting Manufacture Gaskets From ¼” to 28” in Diameter. Silicone rubber material is available in various thicknesses from 0.005” to 0.50”.


A Choice of Rubber Material

Alpha Die Cutting, located in San Diego, offers a versatile range of silicone rubber materials. We provide options with a plain backing or Pressure Sensitive Adhesive (PSA) on one side, and a selection of hardness levels.

Our low durometer silicone rubber gaskets (10A, 20A, 30A) excel in environmental sealing, requiring relatively low closure force. On the other hand, solid gaskets in the mid to higher durometer range are designed for applications where higher closure forces are necessary. These gaskets find common use in metal or rigid enclosures with the appropriate bolt pattern to ensure proper compression of a sturdy gasket.


Diverse Silicone Rubber Options

While silicone rubber is commonly found in red, Alpha Die Cutting offers an extensive range of color choices, including white, cream, black, yellow, green, blue, brown, and clear. In addition to solid silicone, we provide silicone sponge and silicone foam materials. Discover the versatile world of silicone rubber with us.
