Silicone Products Silicone Profiles

Bellofram’s silicone profiles are engineered to deliver reliable performance in sealing, gasketing, and insulation applications across a wide range of industries. Produced through precise silicone extrusion, these profiles offer excellent durability, flexibility, and thermal resistance, making them a dependable choice for both standard and highly specialized applications.

Silicone Extrusion - Custom Shapes and Profiles

Our extruded silicone products are available in a variety of geometries, including traditional shapes like rectangles, cords, and tubes, as well as more complex designs such as U-profiles, P-profiles, double-P-profiles, D-profiles, T-profiles, and E-profiles. With full in-house die-making capabilities, we can produce custom silicone profiles tailored to meet your specific design requirements, whether you need high-volume production or small custom runs.

Each silicone rubber extrusion is available in durometers ranging from 30 to 80 Shore “A,” providing a broad spectrum of hardness options to suit varying mechanical and environmental demands. Our silicone extrusion profiles maintain their physical properties across a wide temperature range — from -85°F to +400°F — making them ideal for applications subject to heat, cold, or fluctuating conditions.

Versatile Extruded Silicone

Bellofram’s extruded silicone materials are formulated with performance and compliance in mind. We offer flame-retardant options that meet UL 94 V-0, UL HB, and other key standards. For applications that involve contact with food or water, such as in medical or food-grade equipment, we also offer FDA compliant and NSF 51 certified silicone profiles. This ensures that your finished product meets safety and regulatory expectations without compromising on performance.

The versatility of our silicone extrusion capabilities allows us to serve a wide variety of markets, including aerospace, automotive, HVAC, medical, electronics, and more. Whether used for sealing enclosures, insulating against temperature extremes, or absorbing vibration, our profiles provide consistent and dependable performance.
