4950 Series Acrylic Foam Tape

3M 4950 is a double-sided acrylic foam tape supplied in a continuous roll. The white tape measures three-quarter inch wide and five yards long with a thickness of 45 mil.

Indoor and outdoor bonding for industrial use

The tape suits installers who need a conformable foam carrier that performs between 50 and 200 degrees Fahrenheit. It is not intended for buyers who require a thinner film tape, a different adhesive chemistry or a product rated beyond the stated temperature range.

Questions about this item

What surface temperature range must the mounting area stay within for the 4950 tape to bond properly?

The tape performs between 50 and 200 degrees Fahrenheit, so the surface must remain in that range during and after application.

Will the 3/4-inch width cover the full flange on my existing metal bracket?

The roll is 3/4 inch wide; measure your bracket flange to confirm the tape matches or exceeds that dimension.

How can I verify the acrylic foam has achieved full adhesion after installation?

After the recommended dwell time, the bond should resist peel force and show no visible gaps or liner residue along the 5-yard length.
