4950 Double Sided Acrylic Foam Tape

First, 4950 double sided foam tape delivers strong structural bonding performance for a wide range of industrial applications. It features a white acrylic foam core with a thickness of 1.1 mm, combined with a high-performance pressure-sensitive adhesive system on both sides.

In addition, this double sided foam tape bonds effectively to high surface energy materials such as metal, glass, painted surfaces, and selected plastics. It replaces traditional mechanical fasteners like screws, rivets, and welding, while maintaining a clean and seamless finish.

Moreover, the firm foam structure improves stress distribution and enhances long-term bonding stability. As a result, this tape performs reliably in demanding environments.

Finally, it provides a simple and efficient mounting solution for industrial, automotive, and construction applications.

Key Performance Features

Strong Structural Bonding：High-performance double sided tape designed for reliable bonding on metal, glass, and coated surfaces.

Firm Acrylic Foam Core：The foam structure provides stress distribution and long-term bonding stability.

Excellent Environmental Resistance：Performs well under moisture, temperature variation, and industrial conditions.

Vibration and Impact Resistance：Absorbs stress and reduces fatigue in structural joints.

Versatile Industrial Tape：Suitable for both light-duty and heavy-duty mounting applications.

Application Areas

4950 double sided foam tape is widely used in:

• Trim and molding attachment
• Exterior panel sealing and structural bonding
• Wall and door panel assembly
• Glass to metal bonding applications
• Transportation and vehicle panel installation
• Appliance and construction structural assembly
• Signage and metal frame installation
• Industrial surface mounting applications

It also functions effectively as a double sided mounting tape for structural installation where screws or rivets are not preferred.

In light-duty applications, it can also be used as a double sided rug tape, providing stable adhesion for carpets, mats, and flooring materials.

With high adhesion strength and durability, it is considered one of the strongest double sided tape solutions for industrial and commercial use.

Surface Preparation

For optimal bonding performance:

• Clean surfaces with 70/30 IPA and water solution
• Remove oil and grease with suitable cleaners
• Abrade oxidized or contaminated surfaces if needed
• Use adhesion promoters for plastics and coated materials
• Seal porous materials such as wood or concrete
• Special preparation may be required for glass and low surface energy materials

Pressure Application

Apply firm pressure (~100 kPa / 15 psi) to ensure full adhesive contact.
