L-Profile Silicone Foam Seal Strip

Product Overview

L-Profile Silicone Foam Seal Strip is a flexible closed cell silicone foam profile designed for edge sealing, corner protection, gap filling and thermal insulation applications. The unique L-shaped cross section allows the seal strip to conform to corners and edge transitions, providing reliable sealing performance for panels, enclosures, doors, windows and industrial equipment.

Made from high-quality closed cell silicone foam rubber, this L-profile seal strip offers excellent compression recovery, low compression force and long-term durability. It maintains reliable sealing performance under repeated compression and exposure to heat, moisture, UV radiation and outdoor environments.

Features

• L-shaped cross section for corner, edge and flange sealing applications
• Closed cell silicone foam structure with excellent sealing, cushioning and insulation performance
• Excellent compression recovery and low compression set for long-lasting sealing reliability
• Wide temperature resistance range for demanding industrial environments
• Outstanding resistance to weathering, UV and ozone aging for outdoor applications
• Soft and flexible foam construction for easy installation and effective gap compensation
• Available in various sizes, densities and colors for OEM sealing requirements

Length Selection Guide

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

• Small profiles: Available in longer lengths such as 3 m and 10 m, suitable for continuous sealing applications.
• Large profiles: Usually supplied in 1 m or 3 m lengths to meet standard shipping requirements.
• Bulk orders: Longer rolls or customized lengths may be available depending on quantity and production requirements.

Please select the available length option for each size specification. Contact us for special length requirements.

Applications

L-Profile Silicone Foam Seal Strip is widely used for:

• Electrical cabinets and control panel enclosures
• Machinery and equipment housings
• Doors, access panels and inspection covers
• HVAC systems and ventilation equipment
• Solar panels and outdoor electrical equipment
• Automotive and transportation applications
• Industrial edge sealing, cushioning and vibration reduction

The L-shaped design provides an effective sealing solution where a standard flat seal strip cannot provide sufficient corner coverage and edge sealing performance.
