Silicone Rubber VS EPDM: What’s the Difference

When it comes to choosing the right material for your project, it is important to consider the properties of each option. In this blog post, we will compare the properties of silicone rubber and Ethylene-Propylene Diene Monomer (EPDM) to help you decide which option is best for you.

What are silicone rubber and EPDM?

Silicone rubber and EPDM (ethylene propylene diene monomer) are two of the most popular types of rubber. They both have a wide range of applications, but there are some key differences between them.

Silicone rubber and EPDM are two types of synthetic rubber. They are both made from petroleum products and have many applications in industry and manufacturing. Silicone rubber is known for its heat resistance and flexibility, while EPDM is known for its weather resistance and durability. Both materials are widely used in the construction industry, such as roofing membranes, flooring and floor covering. They have excellent resistance to water and chemicals, so they are often used for a variety of applications.

WHAT IS SILICONE RUBBER?

Silicone rubber is a synthetic rubber that is made from silicon, oxygen, and other chemicals. It is heat resistant and has a wide temperature range, making it perfect for applications where other rubbers would break down. Silicone rubber also has good electrical insulating properties and is resistant to water and chemicals. This rubber is known for its resistance to high temperatures and its flexibility. It can be used in a variety of applications, including electrical insulation, automotive components, cookware, and medical devices. Silicone rubber is a thermal shock resistant elastomer that can withstand high temperatures. It can be used in applications requiring resistance to chemicals and water, such as food packaging. It also has excellent abrasion resistance and electrical insulating properties, making it ideal for use in electrical insulation.

WHAT IS EPDM?

EPDM is a synthetic rubber that offers excellent resistance to ozone, sunlight and weathering. It also has good chemical resistance and can withstand extreme temperatures. EPDM is commonly used in roofing applications, but can also be found in gaskets, seals and hoses. EPDM has the chemical formula CH2=CH(CH3)2, and the melting temperature is approximately -40°C. The main components of EPDM are dimethylpentadiene and dimethylisoprene. Dimethylisoprene is the most important component and gives EPDM its resistance to ozone, sunlight, weathering and cold temperatures.

What are the key differences between silicone rubber and EPDM?

There are many types of rubber, each with its own unique properties. Two of the most common types of rubber are silicone rubber and Ethylene Propylene Diene Monomer (EPDM) rubber. Although both materials are elastomers (i.e., they can return to their original shape after being stretched or compressed), they have several key differences.

Silicone rubber is a synthetic material made from silicone, a siloxane (a molecule consisting of silicon and oxygen atoms). Silicone rubbers are resistance to high temperatures and have good electrical insulating properties. They are often used in applications where these properties are necessary, such as in high-voltage electrical insulation, gaskets and seals for engines and other machinery, cooking utensils, and medical implants.

EPDM rubber is also a synthetic material, made from a copolymer of ethylene and a synthetic diene (a compound containing two carbon atoms). EPDM rubbers have good resistance to heat, weathering, and chemicals. They are often used in outdoor applications such as seals on car doors and windows, hoses, tubing, and wire insulation.

There are other important differences between silicone rubber and EPDM rubber. Silicone rubbers have poorer tear resistance than EPDM rubbers; however, they have better compression set resistance (i.e., they maintain their shape better when compressed over time). Silicone rubbers also have lower density than EPDM rubbers; however, they have higher specific heat capacity (i.e., they can absorb more heat before becoming hot themselves).

Silicone rubber and EPDM are both versatile materials that have a variety of applications. They are both elastomers, meaning they have the ability to return to their original shape after being stretched or compressed. However, there are some key differences between these two materials.

Silicone rubber and EPDM Difference in properties: flexibility, heat resistance, chemical resistance

Silicone rubber and EPDM are two types of synthetic rubber. They are both used in a variety of applications, but there are some important differences between the two. Silicone rubber is more flexible and has better heat resistance than EPDM. silicone rubber has a much higher temperature range than EPDM. Silicone rubber can be used in temperatures as high as 400 degrees Fahrenheit, while EPDM starts to break down at around 200 degrees Fahrenheit. This makes silicone rubber a better choice for applications where high temperatures are involved. It is also less resistant to chemicals and UV radiation.  This makes it a good choice for applications where it will come into contact with harsh chemicals or solvents. Silicone rubber also shows resistance to oil and grease, which makes it a good choice for applications where dirt and debris is a concern. It is also resistant to acids, alkalis, and chlorine. Silicone rubber has better adhesion, even to a variety of substrates, including metals, glass and ceramic. It also has low hysteresis.

Silicone rubber and EPDM Difference in Weathering

Weathering is the process of breaking down and altering materials by the action of wind, water, ice, and other atmospheric conditions. Weathering can be a problem for many different materials, but it is especially an issue for silicone rubber and EPDM. These two materials are often used in applications where weathering resistance is important, so it is important to understand the difference between them.

Silicone rubber has excellent weathering resistance thanks to its unique chemical structure. The main chain of the polymer is made up of silicon and oxygen atoms, with relatively few carbon atoms. This makes the material resistant to oxidation and UV degradation. In addition, silicone rubber does not absorb water, so it is not affected by humidity or rain.

EPDM also has good weathering resistance, but for different reasons.

Ethylene propylene diene monomer, or EPDM, is a type of synthetic rubber. It is used in a variety of applications, such as in seals and hoses. EPDM has good weathering resistance, but for different reasons than other types of rubber.

EPDM is resistant to both ultraviolet light and ozone. These properties make it ideal for outdoor applications. Other types of rubber, such as natural rubber, are not as resistant to these elements and will degrade over time.

EPDM also has good chemical resistance. It is not affected by acids or alkalis. This makes it ideal for use in environments where other materials would be corroded by the chemicals present.

Overall, EPDM is a versatile material that can be used in a number of applications due to its superior weathering and chemical resistance.
