What are the limitations of using extrusion rubber material in some applications?

Oct 23, 2025

Hey there! As a supplier of extrusion rubber materials, I've seen firsthand the wide range of applications these materials are used in. But like any product, extrusion rubber materials have their limitations. In this blog post, I'll dive into some of the key limitations you might encounter when using extrusion rubber materials in various applications.

1. Temperature Sensitivity

One of the most significant limitations of extrusion rubber materials is their sensitivity to temperature. Most rubber compounds have a specific temperature range within which they can perform optimally. When exposed to temperatures outside this range, the rubber can experience significant changes in its physical properties.

For instance, at high temperatures, rubber can start to lose its elasticity and become brittle. This can lead to cracking and failure of the rubber component. On the other hand, at low temperatures, rubber can harden and lose its flexibility, making it less effective in applications where flexibility is crucial.

Take Adhesive Fluorosilicone Rubber as an example. While it has excellent adhesive properties, it also has a limited temperature range. If used in an environment where the temperature fluctuates widely, it might not perform as expected.

2. Chemical Resistance

Another limitation is the chemical resistance of extrusion rubber materials. Different rubber compounds have varying degrees of resistance to different chemicals. Some rubbers are highly resistant to certain chemicals, while others can be easily damaged by them.

For example, if you're using a rubber component in an application where it will come into contact with strong acids or bases, you need to choose a rubber material that has good chemical resistance. Otherwise, the rubber can degrade over time, leading to leaks, failures, or reduced performance.

Fluorosilicone Rubber for Strap has decent chemical resistance, but it might not be suitable for all chemical environments. Before using it in a chemical - rich application, it's essential to test its compatibility with the specific chemicals involved.

3. Wear and Tear

Extrusion rubber materials are also subject to wear and tear. In applications where the rubber component is constantly in motion or in contact with other surfaces, it can experience abrasion. Over time, this abrasion can cause the rubber to wear down, reducing its thickness and integrity.

In high - friction applications, such as conveyor belts or seals in moving machinery, the rubber needs to be able to withstand a certain amount of wear. However, some rubber materials are more prone to abrasion than others. If the wrong rubber is chosen for a high - wear application, it will need to be replaced frequently, which can be costly and time - consuming.

4. Aging and Degradation

Rubber materials can age and degrade over time. Exposure to factors like sunlight, oxygen, and ozone can cause the rubber to break down chemically. This degradation can lead to changes in the rubber's physical properties, such as reduced elasticity, increased hardness, and discoloration.

For outdoor applications, the aging process can be accelerated. For example, a rubber seal used in an outdoor structure might be exposed to sunlight and rain, which can cause it to degrade faster. To mitigate this, special additives can be added to the rubber during the manufacturing process, but these additives can only slow down the aging process, not stop it completely.

5. Dimensional Stability

Maintaining dimensional stability can be a challenge with extrusion rubber materials. During the extrusion process, the rubber can experience some shrinkage or expansion. This can be a problem in applications where precise dimensions are required.

For example, in the manufacturing of rubber gaskets for machinery, even a small deviation in dimensions can lead to leaks or improper fitting. While manufacturers try to control the extrusion process to minimize dimensional changes, it's still a limitation that needs to be considered.

6. Cost

Cost can also be a limitation when using extrusion rubber materials. Some high - performance rubber compounds, such as Flame Retardant Fluorosilicone Rubber, can be quite expensive. In applications where cost is a major factor, it might not be feasible to use these high - end rubber materials.

However, it's important to balance cost with performance. Sometimes, spending a bit more on a high - quality rubber material can save money in the long run by reducing the need for frequent replacements and maintenance.

7. Processing Limitations

The extrusion process itself has some limitations. It can be difficult to achieve complex shapes with extrusion rubber materials. While extrusion is great for producing long, continuous profiles, creating intricate or highly detailed shapes can be a challenge.

If you need a rubber component with a very specific and complex shape, other manufacturing processes like injection molding might be more suitable. But if you choose extrusion, you'll be limited to shapes that can be extruded.

Mitigating the Limitations

Despite these limitations, there are ways to work around them. For temperature sensitivity, you can choose a rubber material with a wider temperature range or use insulation to protect the rubber from extreme temperatures. In terms of chemical resistance, thorough testing and proper material selection can ensure compatibility.

To reduce wear and tear, you can use rubber materials with better abrasion resistance or apply protective coatings. For aging and degradation, regular inspections and timely replacements can help maintain the performance of the rubber component.

Conclusion

In conclusion, while extrusion rubber materials are versatile and widely used, they do have their limitations. Temperature sensitivity, chemical resistance, wear and tear, aging, dimensional stability, cost, and processing limitations are all factors that need to be considered when choosing extrusion rubber materials for an application.
