Silicone Rubber Sheet: How This Rubber Sheets Can Help The Industry?

Posted by David Kenton on June 28th, 2019

For quality and for extensive range of applications, rubber sheets are manufactured with various thickness to satisfy demanding clients. To various types of stresses during mechanical, electrical, and environmental changes, outdoor insulators are used in distribution and transmission systems. Under the humid and contaminated conditions, the selection and outdoor design insulators are primarily dependent on the performance.

As durable and sturdy materials lend, the silicone rubber sheet is undeniable for human life. The sheet is used in a variety of appliances, products, and equipment along with multiple industries. For its exceptional properties, the silicone sheet is considered as one of the best sheets among the various types of rubber.

For very high temperatures and even fire, the sheet provides excellent resistance. The sheet has specific properties like good thermal conductivity, high tensile strength, and elongation. In the last few decades, the silicone sheet is extensively used for outdoor insulation. While resulting in isolated water droplets, the low surface energy of the silicone sheet materials exhibits the formation of the continuous layers.

Due to the superior property of hydrophobicity, the silicone rubber sheet offers many benefits as compared to glass and porcelain insulators. To provide high surface resistance and to minimize leakage current flow, the better flashover performance of the silicone sheet forms a resistance for the formation of uniform water layers.

The sheet is vulnerable to degradation and aging due to the organic nature while offering several benefits to the industry. There are discrete droplets form on the surface of silicone rubber insulators, under the wet and contaminated conditions. There is a high at the junction of water, insulator, air and insulator surface, as numerical simulations of the electrical field revealed that the electrical area has the right intensity.

There is development partial arcs and corona, as high electric field stress at the edge of the water droplets. While leading to the flashover, these partial discharges and arcs lead to the reduction of surface hydrophobicity.

Benefits Of EPDM Membranes:

While known as EPDM rubber based membranes, the EPDM waterproofing membrane is a single ply. For the building basement, roofs, expansion joints, and basements. There are some of the benefits of the EPDM membrane, which are as follows:

Superior Elongation & Mechanical Strength:

With a tensile strength of over 9 MPA, the EPDM waterproofing membrane has an elongation of over 300%. During the stresses, it takes care of the structural movements of the building. While the building will not crack under the load, the membrane takes care of the building settlement. When compared with the box type waterproofing, the installation of the EPDM membrane is a lot quicker.

Superior Aging Properties:

The membranes are ozone and UV resistant. When exposed to the UV, the membrane performs very well as long as they are not physically damaged. On the structure, it adds negligible load. Without adding significant load to the structure, it can be placed on brickbat Coba, podium areas, and waterproof roofs.

Installing With Ease:

There is no need for torches or flames to install the EPDM membranes, until bitumen base membranes. While using the bonding adhesive, the EPDM membranes are being installed. It has been found that the installation is very safe and quick. For the aircraft hoses, fuel pump diaphragms, gaskets, and oil lined tubing, the nitrile rubber sheet performs well. The nitrile material is used in applications involving not only for fuel, oil, and chemical resistance, due to the strong strength and versatility. These applications need resistance to the water, heat, abrasion, and gas permeability.


For the sealing applications, the nitrile rubber sheet makes it an excellent solution. For the service temperatures, up to 250 F, the sheet has excellent resistant to petroleum products and can be compounded for service. For the most severe automotive applications, the sheet can provide excellent temperature resistance. There are other applications, as well.

The Sheet Is Suitable For The:

• Nitrile roll covers
• Low-temperature applications
• Oil resistant applications
• Hydraulic Hoses
• Nitrile tubing

Benefits Of The Sheet:

There is some excellent benefit to the sheet, which is as follows;

• Tensile strength
• Good compression set
• Unique solution for sealing applications
• Resistance to abrasion
• Resistance to heat
• Resistance to water
• Resistance to abrasion
• Resistance to gas permeability


While involving a high solvent such as nitro hydrocarbons, the nitrile sheet should not be used in other applications. Hence, caution should be taken when one uses the sheet.
