Multi-Color D-Profile Silicone Foam Seal Strip

Product Overview

Multi-Color D-Profile Silicone Foam Seal Strip is a flexible closed-cell silicone foam sealing profile designed for thermal insulation, vibration damping, weather sealing and gap protection. Its rounded D-shaped profile provides a compressible sealing surface that adapts to mating surfaces and helps close gaps.

Available in multiple colors and profile sizes, this silicone foam seal strip can be selected to meet both functional sealing requirements and visual or equipment identification needs.

The closed-cell silicone foam construction provides good resistance to heat, UV exposure, ozone, weathering and aging, making it suitable for demanding indoor and outdoor applications.

Length Selection Guide

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

• Standard lengths: Most specifications are available in common lengths such as 1 m, 3 m, and 10 m, suitable for sample testing, replacement parts, and regular applications.

• Large profiles: Due to their larger dimensions and shipping requirements, some long-length options may be limited by standard transportation methods. These profiles can be shipped by express, air freight, or sea freight according to customer requirements.

• Bulk orders: For wholesale orders and engineering projects, we offer longer rolls, custom lengths, and production quantities based on project requirements.

• Custom production: If a requested size or length is not currently listed, we can manufacture it using our existing extrusion tooling. 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.

Application

• Allow 24 hours for full bonding

Available Specifications

Multiple Multi-Color D-Profile Silicone Foam Seal Strip specifications are available in different cross-section sizes, model numbers, colors and lengths. Select the required W × H profile, model number, color and length from the product options.

Size Chart

Multiple D-profile silicone foam sizes are available to accommodate different gap widths, sealing surfaces and compression requirements.

Refer to the corresponding profile image and W × H dimensions to identify the required cross-section before selecting the product option.

Size Selection

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

For larger gaps, select a profile with sufficient cross-section 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.

Color Selection

Multiple colors are available for different application and identification requirements.

Standard colors can be selected from the available product options. For non-standard colors or specific color matching requirements, contact us to confirm availability and minimum order requirements.

Length Selection Guide

Silicone foam seal strips are available in different lengths depending on profile size, color, 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.

Silicone Foam Material

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

Its closed-cell structure helps provide effective gap filling while reducing moisture absorption. Silicone foam also performs well in applications exposed to heat, UV radiation, ozone and outdoor weathering.

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