Superior Sealing and Durability: D-Type Rubber Profile Manufacturing

D-Type Rubber Profiles (D-Strips / D-Gaskets) are the most effective solution for applications requiring robust sealing, reliable weatherstripping, and effective buffering. As Rubbersan, we manufacture high-strength, long-lasting D-Section Extrusions tailored to your specific industrial needs.

Going beyond standard dimensions, we offer production capabilities in custom sizes, specific hardness levels, and materials including EPDM, Neoprene, Silicone, and custom colors.

Why Choose D-Section Profiles?

Thanks to their geometric structure, D-section gaskets create a tight compression seal and possess high elasticity to return to their original form after deflection.

• Maximum Sealing: Prevents the passage of moisture, dust, air, and noise. Ideal as a perimeter seal (weatherstripping).
• Vibration Damping & Buffering: Provides soft closing for access panels, doors, and machinery components; acts as a buffer to prevent friction and absorb minor impacts.
• Flexible Mounting: Easy application with options for pressure-sensitive adhesive (PSA) backing or secure channel mounting.

Material Diversity and Application Areas

We process the rubber compound best suited for your environmental conditions to ensure optimal performance and longevity.

1. EPDM D-Profile (Weather and UV Resistant)

The ideal material for outdoor applications and exposure to the elements.

• Features: Superior resistance to UV rays, ozone, and extreme hot/cold conditions.
• Applications: Automotive door seals, exterior glazing systems, and industrial weather seals.

2. Neoprene D-Profile (Oil & Chemical Resistance)

Reliable performance in challenging industrial settings.

• Features: Resistant to oils, greases, and various chemicals; maintains stability across a wide temperature range.
• Applications: Machine covers, industrial equipment gaskets, and engine room insulation.

3. Silicone D-Profile (High Heat & Hygienic)

Manufactured for extreme temperatures or where hygiene is critical.

• Features: Retains structural integrity from −60∘C to +250∘C. Can be produced in food-grade (FDA) quality.
• Applications: Industrial oven and furnace door gaskets, autoclaves, and food processing machinery.

4. Custom Specs: Hardness and Form

We offer custom hardness production from 20 Shore A (Soft Sponge) to 90 Shore A (Hard Rubber). Additionally, you can choose between Solid D-Profiles or Hollow (Sponge/Air Cell) D-Profiles based on the required compression force.

Technical Specifications and Custom Die Manufacturing

We specialize in custom die manufacturing based on your technical drawings. This ensures that the base width, wall thickness, and inner/outer radius are produced with the precise dimensional tolerances required for your project.
