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

Product Overview

D-Profile Closed-Cell Silicone Foam Seal Strip 11–19 mm is a flexible sealing profile designed for thermal insulation, weather sealing, gap protection and cushioning applications. Its rounded D-shaped cross section provides a compressible sealing surface that conforms to mating surfaces and helps close gaps.

Made from closed-cell silicone foam, this profile combines flexibility with good resistance to heat, UV exposure, ozone, weathering and aging. The closed-cell structure also helps limit moisture absorption, making it suitable for both indoor and outdoor applications.

The 11–19 mm size range is suitable for applications requiring a compact D-profile with sufficient compression and sealing contact.

Size Selection

Choose the appropriate profile according to the gap width, sealing surface, required compression and available installation space.

For larger gaps within this size range, select a profile with sufficient height to provide adequate compression and sealing contact. Avoid excessive compression, which may increase installation force and affect the service life of the foam seal.

For thermal insulation and vibration damping applications, select a profile that provides sufficient contact area while maintaining the required compression.

Length Selection Guide

Silicone foam seal strips are available in different lengths depending on profile size, application requirements, shipping method and order quantity.

• Standard lengths: Many specifications are available in common lengths such as 1 m, 3 m and 10 m.
• Large profiles: Some larger profiles may have limited long-length options because of transportation requirements.
• Bulk orders: Longer rolls, custom lengths and production quantities can be supplied for wholesale and engineering projects.
• Custom production: If a requested size or length is not listed, suitable existing extrusion tooling may be available. Additional tooling charges may not apply when suitable existing tooling is available.

Please select the available length option for each specification. For special lengths, bulk orders, or customized requirements, please contact us for a suitable solution.

Silicone Foam Material

Closed-cell silicone foam provides a combination of flexibility, compressibility, thermal resistance and environmental durability.

Compared with many conventional foam materials, silicone foam performs well in applications exposed to heat, UV radiation, ozone and outdoor weathering. Its closed-cell structure helps reduce moisture absorption and provides effective gap-filling performance.

For applications requiring specific foam density, hardness, color, temperature resistance or profile dimensions, customized silicone foam sealing profiles can be considered.

OEM & Custom Profiles

For custom dimensions, foam density, hardness, colors, lengths or large-volume requirements, we can provide OEM silicone foam extrusion solutions based on your application and sealing requirements.
