Rubber strips are versatile components widely used in various industrial applications due to their durability and adaptability. Typically produced from vulcanized rubber, these strips can be manufactured via slitting calendered or press-cured sheets, or through direct extrusion processes. The result is a rectangular cross-section rubber piece that is sold either by the linear meter or in pre-cut lengths, allowing for flexibility in usage. Common dimensions for rubber strips include widths ranging from 10 mm to 300 mm and thicknesses between 1.5 mm and 25 mm. They are often available in continuous rolls, usually between 5 m and 50 m long, or as cut pieces depending on the specific requirements of the application. The choice of rubber material plays a crucial role in determining the strip's suitability for different environments. For instance, SBR is a general-purpose rubber that offers a balance between performance and cost, while NBR is specifically formulated for oil and fuel resistance, making it ideal for automotive applications. In contrast, EPDM is highly effective in weather and steam resistance, which is beneficial for outdoor use.
Rubber strips also come in various hardness levels, typically ranging from 40 to 80 Shore A, which can influence their performance characteristics such as flexibility and resistance to wear. The edges of these strips can either be slit, resulting in a slightly rough surface, or extruded, offering a smooth and precise edge. Additionally, adhesive-backed versions are available, providing convenient installation options for applications that require bonding to surfaces. These strips find applications in sealing doors, windows, and hatches to prevent air and water ingress; serving as bumpers and edge guards to protect machinery; and acting as wear strips on equipment to reduce friction. Furthermore, they can be utilized as conveyor skirting, anti-vibration pads, and for weather sealing in outdoor enclosures. Custom sizes and materials can also be ordered to meet specific industrial needs, adhering to tolerances of ±0.5 mm for width and ±0.3 mm for thickness in slit strips, and ±0.2 mm for extruded profiles. According to ASTM D2000, rubber materials are classified based on their properties, aiding in the selection of the right rubber strip for the intended application.
