Silicone Products Silicone Cords

Bellofram’s silicone cords are engineered for applications where durability, flexibility, and temperature resistance are essential. Manufactured from high-quality silicone rubber, these cords are ideal for sealing, gasketing, and insulating in environments where performance under pressure is non-negotiable. Available in diameters up to 2.5” and durometers ranging from 30 to 80 Shore “A”, our solid silicone cords offer the versatility and reliability needed across a range of industries.

These solid silicone seals are produced using precise extrusion processes, resulting in consistent diameter and shape along the entire length of the cord. Whether used as-is or cut to a specific length for a custom gasket, the uniformity of our extruded cords ensures reliable sealing and easy installation. Applications range from industrial equipment and electrical enclosures to lighting systems and appliances — anywhere a resilient, high-performance seal is required.

With a wide working temperature range of -85°F to +400°F, Bellofram’s extruded silicone cords are built to perform in both high-heat and sub-zero environments. This thermal stability makes them an excellent choice for both indoor and outdoor applications, particularly where temperature fluctuations or exposure to heat sources are present. The material resists cracking, hardening, and degradation over time, even under prolonged exposure to UV light and ozone.

Our silicone sealing cords offer excellent resistance to environmental factors, making them suitable for harsh or demanding conditions. They maintain flexibility and shape after repeated compression and are non-reactive, non-toxic, and compliant with many regulatory standards depending on the formulation. These characteristics make silicone rubber cords a go-to solution in industries such as aerospace, automotive, medical devices, food processing, and electronics.

If your application requires a tailored sealing solution, we can produce custom extruded silicone cords in various diameters, hardness levels, and colors. Whether you need small quantities for prototyping or large-volume production, our in-house manufacturing capabilities ensure consistency and quality with every batch.

From simple seals to complex enclosures, Bellofram’s solid silicone cords deliver a dependable, long-lasting solution. With excellent thermal, mechanical, and environmental performance, these extruded silicone cords offer the peace of mind that comes from materials designed to perform reliably in even the most challenging conditions.
