Aluminum Foil Tape 425

Applications and key characteristics

• High thermal conductivity enhances heating or

cooling efficiency

• High heat reflectivity and flame resistance

protects temperature-sensitive materials

against heat and flame damage and hot spots

• Reflect light

• Seal and protect against moisture, solvents,

and dust

• Resist outdoor weathering and UV degradation

for long term performance

Damping Foil Tape 2552

Applications and key characteristics

• Converts vibrational energy to negligible heat that

readily dissipates

• Reduces structure-borne noise in metal and

composite panels and support structures

• Reduces vibrational fatigue to decrease wear

and tear on parts and lower the risk of part

loosening and displacement

• Effectively damps with minimal coverage

• Pressure sensitive for easy application

PTFE Film Tape 5490

Applications and key characteristics

• Wrap web rollers with a slippery, low energy

surface for smoother material movement

• Cover web former edges to minimize friction

during folding

• Anti-stick for ready release and clean-up of hot

plastic; prevent plastic film from sticking to

heat bar

• Protect surfaces against heat, chemicals,

and friction

• Conforms to rollers for easy application
