Custom Silicone Rubber Gaskets

Silicone rubber gaskets are devices made from durable silicone rubber materials that offer a wide range of uses in different industries.

From the food sector to healthcare, silicone gaskets are resistant to high temperatures and harsh environments, making them a top choice.

Thanks to the durable silicone gasket materials, they can effectively prevent leakage of air, gasses, or fluids. This prevents chemicals from contaminating your area, keeping your station sterile.

In healthcare, silicone gasket material properties prevent contamination when medical devices are sterilized. In food processing, silicon gaskets maintain the hygiene and safety of food, even at high temperatures.

Meanwhile, in the electronics industry, silicone gaskets protect sensitive components from dust or moisture, preventing electrical hazards altogether.
Silicone gaskets are made to last, requiring less maintenance and saving you some hefty repair costs. It features low compression, high biocompatibility, and excellent electrical insulation properties.

What Are Silicone Gaskets?

Silicone gaskets are rubber devices that seal two surfaces. They have water-repelling materials, designed to prevent gas or fluids leakages and contamination. Silicone gaskets are beneficial due to their high heat resistance, flexibility, and durability, which allow them to be used in various applications.

Compared to other materials like EPDM (Ethylene Propylene Diene Monomer) or PTFE (Polytetrafluoroethylene) gaskets, this type of gasket material has low maintenance while offering high performance in both very low to very high temperatures. It also has excellent durability to UV light, moisture, or certain chemicals, making it highly useful in the medical, food, and electronics industries.

Silicone Gaskets Features & Benefits

What makes silicone gasket material properties so special? Well, they offer a range of benefits

  • Resistant to High & Low Temperatures: Silicone gaskets can withstand continuous use at extreme temperatures, ranging from as high as 392°F to as low as -94°F.
  • Top-Tier Electric Insulators: Silicone gaskets are the top choice for superior electrical insulation. Engineered with cross-linking chemical reactions, they remain stable and non-reactive even at high temperatures.
  • UV Resistance: Silicone gaskets have excellent durability and resistance to ozone, UV light, or extreme conditions and are great for outdoor use. High-performance silicone gaskets won’t need high maintenance, saving you recurrent repair costs.
  • FDA Approved: Silicone gaskets are widely used in medical equipment and food processing instruments. Their FDA approval ensures they meet stringent standards for use in environments that demand the highest levels of purity and performance.

Silicone Gaskets Manufacturing

Made from the highest-quality silicone elastomers, our gaskets are crafted through advanced manufacturing techniques such as molding and die-cutting. These elastomers can either be sponge or solid silicone, each offering different benefits.

Solid silicone are best for high-pressure environment, whereas sponge silicone–as the name implies–has a softer texture, making it a better option for sealing in low-pressure applications or cushioning.

In the first process of die-cutting, silicone gaskets that come in custom shapes are then cut into the hem of their exact dimensions. This enables us to maintain the precision of the shape while manufacturing silicone gaskets in a large batch, ensuring both speed and quality.

In the second process, or “molding”, silicone gaskets are crafted with intricate designs, ensuring uniform thickness while maintaining durability throughout the gasket’s structure and material.

The manufacturing process of silicon gaskets involves various processes. The first process is die-cutting, where the silicon gaskets have custom shapes, and cutting the hem into exact dimensions makes them ideal for producing large volumes. Another method is molding, where silicon gaskets

At Rubber Xperts, our process ensures that each gasket meets the highest industry standards for durability and performance, whether it is a solid or sponge silicone gasket.

Types of Silicone Gaskets

Looking for specific silicone gasket types? Rubber Xperts provides you with the best variations there are in the market:

  • Solid Silicone Gaskets: These gaskets are soft but more rigid than sponge silicone. They come with a seal rating of IP67 or higher, offering excellent strength and resilience that make them perfect for high-pressure applications.
  • Sponge Silicone Gaskets: These gaskets have cushioning and padding texture, and can either come in the forms of open or closed-cell. They have one of the highest temperature thresholds—up to 500 degrees Fahrenheit. Sponge silicone gaskets are lightweight and compressible, ideal for environments where flexibility is critical.
  • Silicone Foam Gaskets: This silicone gasket specification comes in a wide range of textures: soft, medium, firm, or extra firm. It can also be open-cell or closed-cell, making it suitable for food and medical applications. Silicone foam gaskets are designed to meet industrial safety standards.
  • Die-Cut Silicone Gaskets: For large-volume silicone gasket uses, this variation is the most economical option. It uses specialized tools to create custom parts, depending on their industrial use.
  • Molded Silicone Gaskets: This silicone gasket material offers the best out of its value; they tend to be more expensive, but they’re also the highest performer.
