EPDM Foamed Composite Sealing Strip

The EPDM Foamed Composite Sealing Strip is a high-performance rubber extrusion profile designed for long-term sealing in industrial, construction, automotive, and equipment applications.
By combining solid EPDM rubber with closed-cell EPDM foam, this composite sealing strip provides excellent elasticity, reliable compression recovery, and outstanding weather resistance.

What Is an EPDM Foamed Composite Sealing Strip?

An EPDM foamed composite sealing strip is a co-extruded rubber profile made from two integrated layers:

Solid EPDM rubber layer for structural strength and tear resistance

Foamed EPDM rubber layer for flexibility, cushioning, and improved sealing performance

This composite structure allows the sealing strip to adapt to uneven gaps while maintaining consistent sealing pressure over time.

Key Features and Benefits

Excellent resistance to UV, ozone, and weather aging

Wide working temperature range from –40°C to +120°C

Closed-cell foam structure for waterproof and dustproof sealing

Low compression set for long-term performance

Good elasticity and vibration absorption

Stable performance in outdoor and industrial environments

Customizable shapes, sizes, and hardness levels

Technical Specifications

Specifications can be adjusted according to customer application requirements.

Typical Applications

EPDM foamed composite sealing strips are widely used in applications that require durable and reliable sealing, including:

Industrial doors and windows

Automotive and truck body sealing

Electrical cabinets and enclosures

Mechanical equipment covers

Solar panel frames and mounting systems

Containers, trailers, and transportation equipment

These applications demand stable sealing performance under long-term exposure to sunlight, temperature changes, vibration, and moisture.

Why Choose EPDM Foamed Composite Sealing Strips?

EPDM rubber is one of the most trusted elastomers for sealing applications due to its excellent durability and environmental resistance.
Compared with solid rubber seals, foamed composite EPDM sealing strips offer:

Better gap-filling capability

Improved compression flexibility

Reduced installation tolerance requirements

Longer service life in outdoor conditions

This makes EPDM foamed composite sealing strips an ideal solution for both static and dynamic sealing needs.
