How to Choose the Right Rubber Material for Your Extrusion

Choosing the correct rubber material is one of the most important decisions in any extrusion project. The wrong material can lead to premature failure, excessive maintenance, or costly redesigns.

Key Factors to Consider

When specifying a rubber extrusion, consider:

• Operating temperature range

• Exposure to UV, ozone, or weather

• Contact with oils, fuels, or chemicals

• Compression and flexibility requirements

• Industry standards or approvals

Common Rubber Materials Explained

EPDM Rubber

EPDM is widely used for outdoor sealing thanks to its resistance to UV radiation, ozone, and extreme weather. It is commonly found in construction, automotive, and HVAC applications.

Silicone Rubber

Silicone offers excellent high- and low-temperature performance and is suitable for food-grade and medical environments. It is often used where cleanliness and thermal stability are critical.

Nitrile (NBR)

Nitrile is the preferred choice for oil and fuel exposure. It is commonly used in automotive, industrial machinery, and hydraulic environments.

Neoprene

Neoprene provides a good balance of weather, chemical, and mechanical resistance, making it suitable for general-purpose sealing.

Expert Material Selection Matters

At Seal Extrusions, material selection is guided by real-world operating conditions — not just datasheets. This ensures extrusions perform reliably throughout their intended lifespan.
