D-Profile Closed Cell Silicone Foam Seal Strip 11–19mm

Product Overview

D-Profile Closed Cell Silicone Foam Seal Strip is a flexible silicone foam sealing solution designed for industrial applications requiring reliable compression sealing, thermal insulation, and weather protection. Featuring a D-shaped profile with a flat mounting surface and rounded sealing surface, this foam silicone strip provides excellent contact pressure and gap-filling performance.

With an 11–19mm profile range, this medium-size D-profile silicone foam seal strip is suitable for equipment enclosures, doors, panels, and industrial assemblies where a balance of flexibility, compression recovery, and sealing performance is required. The closed cell silicone foam structure helps reduce moisture penetration, air leakage, dust ingress, and vibration transmission while maintaining durability in demanding environments.

Key Features

  • D-Profile Design for Reliable Compression Sealing

 The D-profile cross section provides a stable sealing surface with efficient compression characteristics. The flat base allows easy installation, while the rounded top ensures consistent contact with mating surfaces.

  • Closed Cell Silicone Foam Construction

 Closed cell silicone foam offers low water absorption, excellent environmental resistance, and long-term sealing reliability compared with conventional open-cell foam materials.

  • Thermal Insulation Performance

 Silicone foam provides excellent temperature resistance and insulation properties, helping protect equipment from heat transfer and temperature fluctuations.

  • Weather & UV Resistance

 The silicone material delivers outstanding resistance to UV exposure, ozone, aging, and outdoor weather conditions, making it suitable for indoor and outdoor sealing applications.

  • Flexible & Vibration Damping

 The elastic foam structure absorbs vibration and impact while maintaining compression recovery for repeated sealing cycles.
