Features and Benefits
• Thermal impedance:
0.60°C-in2/W (@50 psi)
• High bond strength to most epoxies
and metals
• Double-sided, pressure sensitive
adhesive tape
• High performance, thermally conductive
acrylic adhesive
• More cost-effective than heat-cure
adhesive, screw mounting or clip mounting
Bond-Ply
®
800 is a thermally conductive,
electrically isolating double-sided tape.
Bond-Ply
®
800 is utilized in lighting
applications that require thermal transfer
and electric isolation. High bond strengths
obtained at ambient temperature lead to
significant processing cost savings in labor,
materials and throughput due to the
elimination of mechanical fasteners and
high temperature curing.
Typical Applications
Include:
• Mount LED assembly to troffer housing
• Mount LED assembly to heat sink
• Mount heat spreader onto power
converter PCB or onto motor
control PCB
• Mount heat sink to BGA graphic processor
or drive processor
Configurations Available:
• Sheet form, roll form and die-cut parts
