In industrial engineering, one-size-fits-all is rarely a winning strategy—especially when it comes to sealing, insulation, or protection. That’s where custom silicone extrusion plays a transformative role.

From medical tubing to complex gaskets in aerospace and cleanroom environments, tailored silicone extrusions ensure exact fit, longevity, and superior performance under extreme conditions.

Let’s explore why industries across the board are shifting toward custom silicone extrusion, and how Western Rubbers is helping companies innovate with precision-engineered silicone solutions.

What is Silicone Extrusion?

Silicone extrusion is the process of forcing uncured silicone material through a die to create a continuous profile with a specific cross-section. Once formed, it is cured through heat or other methods to retain the desired shape permanently.

What makes it special?

�� Continuous Lengths – Ideal for sealing long edges and flexible installations

�� Material Flexibility – Custom durometers, grades (FDA, platinum-cured), and colors

�� Highly Customizable – From simple tubes to complex, multi-chamber profiles

The result is a highly versatile product ready to serve diverse functions—be it sealing, cushioning, insulating, or protecting.

Why Choose Custom Silicone Extrusion Over Standard Options?

While standard extrusion profiles may work for basic applications, most industries require a tailored solution to meet specific performance and design criteria.

Here’s why custom silicone extrusion makes a difference:

✅ Exact Fit: No compromise on dimensions or cross-section complexity
�� Application-Specific Materials: Choose FDA-grade, flame-retardant, medical-grade, or conductive silicone
��️ Withstands Extremes: Performs flawlessly across a wide temperature range
�� Superior Sealing Properties: Excellent resistance to water, air, UV, and chemicals
�� Better Product Integration: Perfectly integrates with your equipment or assembly

Whether you're sealing a medical device or insulating a high-voltage cable, customization ensures reliable performance.

Types of Silicone Extrusion Profiles

Western Rubbers specializes in a wide range of silicone extrusion profiles designed to serve both standard and unique requirements.

Some common profiles include:

· U-Channels – Used for edge protection and impact absorption

· T-Profiles – Ideal for joining panels or components

· P-Profiles – Effective for compression sealing applications

· D-Seals – Provide excellent weather sealing for doors and enclosures

· Tubing & Hollow Profiles – Flexible transport of fluids, wires, or air

· Custom Multi-Chamber Designs – Built to your CAD drawings and tolerances

Each profile is tailored with the right wall thickness, hardness, and tolerance levels for peak application performance.

Real-World Example: Medical Equipment Manufacturer

A global medical equipment manufacturer approached Western Rubbers for a seal that would meet FDA compliance, provide consistent compression, and resist both chemicals and sterilization cycles.

The solution?

We developed a custom silicone extrusion using platinum-cured silicone with a specific D-profile and controlled compression set properties. The result was a leak-free seal that exceeded performance tests and improved overall equipment efficiency.
