Product Data Sheet

3M™ VHB™ Tape 4950 is a premium white double-sided acrylic foam tape engineered for strong, permanent bonding in demanding industrial and commercial applications. Featuring a 0.045 inch (1.1 mm) thick firm acrylic foam core, this tape provides superior strength, durability, and gap-filling capability, making it ideal for bonding rigid and slightly irregular surfaces.

Designed with a general-purpose acrylic adhesive on both sides, 3M™ VHB™ 4950 bonds effectively to a wide range of high surface energy materials, including metals, glass, painted surfaces, composites, and many plastics. Its firm foam structure helps distribute stress evenly across the bond line, improving performance and enabling reliable bonding of dissimilar materials.

This high-performance tape offers a fast, clean alternative to traditional fastening methods such as screws, rivets, and welds. It eliminates the need for drilling, grinding, or finishing, while maintaining a smooth, professional appearance. The pressure-sensitive adhesive bonds on contact for immediate handling strength and continues to build over time for maximum long-term adhesion.

In addition to its strong bonding capabilities, 3M™ VHB™ 4950 creates a durable seal against water, moisture, and environmental exposure. Its viscoelastic acrylic foam core absorbs vibration, accommodates thermal expansion, and enhances overall bond integrity in dynamic conditions.

Commonly used across industries such as construction, transportation, electronics, signage, and general manufacturing, this tape is ideal for applications like panel bonding, trim attachment, stiffener bonding, and structural assembly. With its combination of strength, flexibility, and long-term reliability, 3M™ VHB™ Tape 4950 delivers a proven solution for high-performance bonding and sealing applications.
