Custom Die Cut Silicone Rubber Gaskets

Custom Die Cut Silicone Gaskets

Customization is a key feature of these gaskets. They are designed to meet your specific application requirements, whether you need them for a unique industrial process, automotive system, medical device, or any other application.

Silicone Gasket Advantages

Silicone gaskets are made from silicone rubbers, a family of synthetic elastomers.

• Provides environmental sealing
• Offers excellent temperature stability
• Resist ozone, sunlight, weathering, and aging
• Chemically inert
• Good dielectric properties
• Maintain their flexibility at low temperatures
• Can withstand high temperatures

Silicone Gasket Types

Silicone gaskets can be categorized in several different ways. For example, solid silicone gaskets and sponge silicone gaskets are distinct because they have different molecular structures. Hardness or durometer also distinguishes silicone seals. Foam silicone gaskets may be soft like sponge silicone gaskets, but foam silicones are distinct because they contain different ingredients and use a different curing system. Interstate die cuts all of these silicone gasket types.

Solid Silicone Gaskets

Solid silicone gaskets are made of solid rubber materials with a tightly-packed molecular structure.

• They have lower durometers (hardness) and compression rates than sponge silicones
• Not all solid silicones are “soft”, however
• Lower-durometer solid silicones provide strong environmental sealing with low closure force
• Solid silicone gaskets with mid-range durometers require greater closure force

Interstate can also diecut gaskets from relatively hard silicones.

Sponge Silicone Gaskets

Sponge silicone gaskets are made of sponge-like silicone compounds that provide cushioning and padding. Interstate die cuts both basic types of sponge silicone materials: open-cell and closed-cell.

• Open-cell silicone gaskets contain interconnected pockets that, unless the gasket is compressed, allow water, chemicals, and air to pass
• Closed-cell silicone gaskets are filled with nitrogen gas to prevent the passage of these substances at low pressures.

Foam Silicone Gaskets

Foam silicone gaskets are made of soft, medium, firm, or extra-firm silicone grades for different amounts of compressibility.

• They have a lower compression set than sponge silicone gaskets
• Offer improved flame resistance

Interstate die cuts the three basic types of foam silicone materials: open-cell, closed-cell, and silicone rubber that has both open and closed cells. Like solid silicones and sponge silicones, foam silicones have numerous applications.

Silicone Gasket Applications

Custom cut silicone gaskets are suitable for a variety of industries, including but not limited to automotive, aerospace, electronics, food processing, pharmaceutical, etc. They are suitable for applications such as sealing, electrical insulation, shock absorption and heat insulation.
