Thermoset plastics and thermoset rubbers are both common materials used in several everyday materials. In addition, they are also used in a number of different industries. Both thermoset plastics and thermoset rubbers are essential materials in polymers and elastomers. While they are used in the same field, they have unique differences. Below you will find helpful information comparing thermoplastic elastomers and thermoset rubber.

Comparing Thermoplastic Elastomers and Thermoset Rubber

To fully understand the difference between thermoplastic elastomers and thermoset rubber, it’s critical to understand what they are.

Thermoset Elastomers: 

Thermoset elastomers are made from a mixture of polymers. This is often a thermoplastic matrix mixed with rubber-like particles. They are a class of materials that have both thermoplastic and elastomeric properties. The combination of materials used to create them makes them highly versatile and a top choice in many applications. In fact, they are able to withstand various temperatures. They can be hardened with cool temperatures and softened with warm temperatures over and over again. Common applications include the automotive industry, consumer goods, and medical devices.

Thermoset Rubber: 

Unlike thermoset elastomers, thermoset rubber is not resistant to temperatures in the same way. In fact, thermoset rubber is hardened in cool temperatures and cured in warm temperatures. The chemical change that occurs with different temperatures is irreversible. Because of this, thermoset rubber is highly durable and strong. Common applications include tires and auto components, electrical insulation, and other industrial applications.

Notable Differences Between Thermoset Elastomers and Thermoset Rubber

While thermoset elastomers and thermoset rubber are both essential materials in the field of polymers and elastomers, their properties are uniquely different in several ways. Consider the following if you are selecting one of the two options.

Processing Methods: 

The methods used for processing both of the materials are vastly different. Thermoplastic elastomers are processed using methods such as injection molding and blow molding. However, thermoset rubber is usually processed through compression or transfer molding.

Unique Properties: 

Thermoplastic elastomers are versatile and easy to process. This makes them a popular option in many applications. However, thermoset rubbers offer a number of advantages. Some include their strength, durability, temperature resistance, and ease of use. Both have unique properties, so it’s important to understand exactly what you need for your application. 

Price: 

Prices can vary depending on your location and who you purchase your materials from. However, thermoplastic elastomers are often lower in terms of production costs. This is another reason why they are more commonly used as compared to thermoset rubber.

Reversibility: 

As discussed, thermoplastic elastomers are highly versatile as they can be remelted and reshaped with ease. This allows them to be easily recycled as they can go through multiple processing cycles. This is unlike thermoset rubber, as it is irreversible.

Specialty Seals

Speciality seals are a part of various industries, including automotive, medical, aerospace, and industrial. These industries require materials that have just the right properties for the specific application. This is necessary to ensure that the seals are up to the challenge, as the environment is often challenging. An effective seal is critical no matter what issues the environment poses. This is why so many choose thermoplastic elastomers and thermoplastic rubber. Both play crucial roles in the production of speciality seals due to the unique and beneficial characteristics.

When choosing between thermoset elastomers and thermoset rubbers, the choice depends on the unique needs of your application. This includes the environmental conditions, durability requirements, resistance needs, and other factors. The team at Real Seal is skilled and experienced in sealant manufacturing and distribution.
