Product Description

Flexible Corrugated Graphite tape


Flexible Corrugated Graphite Tape with Adhesive made of pure graphite (99% grade) with or without a self-adhesive layer. A standard thickness is 0.8 and 0.5mm and a width availability: 8, 10, 12, 15, 20, 25, 30 mm. The graphite tape has the full chemical resistance (0-14 pH), high thermal resistance up to 900°C and it can withstands a montage pressure 250 N/mm2. The tape is crinkled or corrugated to enhance the tape flexibility.


Main Characteristics and Properties

Excellent resistance to chemical corrosion.

Compressible, conformable, low creep relaxation

Thermal conductive, electrical conductive

Good self-lubricating.

High resilience

Easy to use, low cost. 


Working Temperature Range:

Oxidizing Atmosphere, such as air: 240 °C to 510 °C

Mild Oxidizing Atmosphere of most gasket applications: -240 °C to 850 °C

Non-Oxidizing Atmosphere: -240 °C to 3000 °C

Thermal Conductivity:

Parallel to Sheet Surface: 960 BTU-in/ft2.h.F (140 W/m.K)

Through Thickness: 36 BTU.in/ ft2.h.F (5W/m.K)



Flexible Corrugated Graphite Tape with adhesive can be used as form-in-place gasket, valve stem packing, pump stuffing box packing, thread seal, or other irregular shaped seal/gasket.


Flexible Corrugated Graphite Tape is also the material for making die-formed graphite rings
