D-Shaped Profiles
Versatile D-shaped extruded rubber profiles featuring a flat mounting base and curved compressive sealing face. Widely utilized for enclosure doors, marine fenders, automotive tailgates, and structural hatch gaskets.
Types & Configurations of D-Shaped Profiles
Hollow D Compression Profiles
Internal circular void providing soft, compliant closure under minimal bolt or latch force.
Solid D Impact Bumpers
High-density solid rubber D-section absorbing heavy kinetic impact along truck loading docks.
Self-Adhesive D-Strip Gaskets
Flat base laminated with acrylic adhesive for rapid peel-and-stick enclosure assembly.
Flanged D-Sections with Lip
Side mounting lip with pre-punched holes for mechanical screw or rivet attachment.
Heavy Marine D Fenders
Large bore thick-walled D-sections for tugboats, barges, and marina docks.
Key Industrial Applications

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| EPDM Dense Rubber | Extreme weather, ozone & UV radiation resistance | Automotive door/window seals, building facade gaskets |
| EPDM Sponge / Foam | Low closure force, closed-cell water & dust sealing | Enclosure door perimeter gaskets, electrical cabinet seals |
| Nitrile (NBR) Extrusion | Resists mineral oils, hydraulic fluids & greases | Machinery inspection hatch seals, oil sump gaskets |
| Neoprene (CR) Rubber | Self-extinguishing, marine atmospheric stability | Ship portlights, railway carriage door profiles |
| Natural Rubber (NR) | High tear strength, abrasion resistance & elasticity | Chute edge protectors, quarry screening rubber strips |
