Product Specification

Seals and Gaskets

FLEXOGRAF is binderless. It is chemically resistant and can be used in high temperature just like artificial graphites. It is very anisotropic with respect to characteristics such as gas permiability, electrical resistivity, coefficient of thermal expansion and thermal conductivity.

Flexograf is flexible, compressible and has a high degree of resilience which are special features of this material compared to conventional artificial graphites.

Because of its special characteristics including characteristics of artificial graphites it can be used as gasket, reflective heat shields, corrosion resistant linings, seals, bearings and compressible packings.

Flexograf Advantages :

Asbestos-Free Made from pure Natural Graphite
