Whether used for sealing oven doors or protecting wiring systems, silicone cords are trusted for their durability, safety, and performance.
Silicone cords are produced using an extrusion process. Silicone material—either solid or sponge—is pushed through a shaped die to create a continuous cord. The extruded shape is then cured with heat to achieve its final strength and flexibility.
Silicone cords are available in different forms to suit various needs:
All forms—whether you call them silicone cords, silicone strings, or silicone ropes—offer dependable sealing and insulation for tough industrial conditions.
Silicone rubber cords are known for their excellent performance in tough environments. Whether used as a silicone rope for industrial sealing or as a small-profile string for delicate applications, these cords offer reliable protection and flexibility.
Silicone rubber cords and silicone ropes last longer, perform better in extreme temperatures, and are safer in sensitive environments compared to standard rubber cords. This makes them ideal for high-demand industries like medical, food, automotive, and electronics.
For harsh environments and long-term reliability, silicone rubber cords and silicone ropes are the top choice across industries.
Silicone cords are used across many industries because of their ability to handle heat, moisture, and chemicals. They are flexible, long-lasting, and available in custom sizes, making them a smart choice for sealing and insulation needs.
Silicone rubber cords are widely used in vehicles for door seals, engine gaskets, and wiring protection. They handle high engine temperatures and resist oil and weather damage.
Food-grade silicone cords are used for sealing equipment in food and pharmaceutical plants. They do not react with food, are easy to clean, and meet FDA safety standards.
Silicone cords are used in outdoor and industrial lighting fixtures to keep dust, water, and insects out. They stay flexible and effective even in hot or cold climates.
In aircraft and ships, silicone cords provide airtight and watertight sealing. They resist saltwater, UV rays, and extreme temperatures, making them ideal for demanding conditions.
High-temperature silicone rubber cords are used in ovens, furnaces, and heavy machinery. They keep their shape and seal well even under constant heat.
From small equipment to large machines, silicone cords provide safe and long-term sealing in critical applications.
Silicone cords are available in different types to match specific sealing needs. Choosing the right type depends on the application, temperature range, and pressure conditions.
Silicone cords come in a wide range of diameters and thicknesses. Colors can be customized for identification or industry use—like red for high-temp, blue for food-grade, or clear for visibility.
Reinforced options are available for demanding uses where extra strength and durability are needed, such as in automotive or aerospace settings.
Choosing the right silicone cord ensures proper sealing, long-term performance, and industry compliance. Here are key factors to consider before making a purchase.
Always check the required diameter and tolerance level. A precise fit is important for effective sealing. Tighter tolerance is better for high-pressure or critical sealing areas.
Silicone cords are available in different hardness levels, measured in Shore A. Soft cords (30–40 Shore A) are flexible and compressible. Harder cords (60–80 Shore A) offer stronger seals and hold shape under pressure.
Colors are often used to identify grades and applications:
Choosing the right color can help with quick identification and industry standards.
