Rubber strips with adhesive backing are useful when a seal, cushion, or protective strip needs to stay in a defined position on a suitable surface. The adhesive holds the strip during installation and service; the rubber provides the compression, cushioning, or barrier. Whether the combination works depends on the joint, the surface, and the forces […]
Rubber seals do not have one fixed lifespan. Seals held in storage can remain suitable for years when packaged and stored correctly, while installed seals may need replacement much sooner—or remain effective much longer—depending on the material, fluid, temperature, movement, pressure, and seal design. Shelf life describes the period before installation; service life describes performance […]
To measure window rubber seals for replacement, identify the existing profile, record its attachment and sealing dimensions, and measure the installed seal path. Then compare those details with supplier drawings and verify suitable samples in the window system. Accurate measurements help installers and maintenance teams avoid profiles that pull loose, leave gaps, or make windows […]
Garage door bottom seals close the space between doors and floors, helping limit drafts, dust, debris, and wind-driven rain. Common garage door bottom seal types include T-end, beaded-end, bulb, and J-type profiles. Each combines specific attachment features with flexible sections that contact the floor. For installers, distributors, and door manufacturers, correct selection starts with understanding […]
Extruded rubber shapes are continuous profiles manufactured by forcing uncured rubber compounds through specially designed dies. The profiles are then cured to stabilize their dimensions and develop the required physical properties. Unlike molded rubber parts, which are produced as individual components, extrusions maintain the same cross-section along their length. This makes extrusion suitable for seals, […]
Choosing an extruded rubber manufacturer involves more than comparing unit prices. The supplier must translate a drawing or application requirement into a stable compound, workable die and repeatable production process. For standard cords or strips, sourcing may be relatively straightforward. Custom profiles introduce more variables: material formulation, die swell, curing, dimensional tolerances, splicing, cutting and […]
What Are Extruded Rubber Gaskets? Extruded rubber gaskets serve as continuous sealing solutions with a uniform cross-section. The extrusion process pushes uncured rubber through a die. This method produces long, uninterrupted lengths. These gaskets function as static seals between flat surfaces. They also work in dynamic settings. Engine parts and rotating shafts rely on them […]
Getting an accurate quote for custom rubber extrusions requires detailed specifications. Manufacturers need clear dimensions, proper tolerances, the correct material, and the exact quantity. Any special requirements also matter. Having this information ready streamlines the quoting process. It prevents delays and unexpected costs. Use this checklist as a guide before contacting a manufacturer. Collect each […]
Silicone rubber extrusions can be much more complex than simple tubes, cords, or rectangular strips. A custom profile may combine hollow chambers, sealing lips, mounting channels, ribs, grooves, compression bulbs, and locating features within a single continuous cross-section. The practical limit, however, is not determined by how complicated the CAD drawing looks. A profile must […]
EPDM rubber extrusion is a manufacturing process used to produce continuous rubber profiles for sealing, cushioning, insulation, weather protection, and edge protection. Because EPDM offers strong resistance to sunlight, ozone, water, and changing temperatures, it is widely used for both indoor and outdoor applications. The extrusion process allows manufacturers to create profiles with consistent cross-sectional […]
