Fabric bakelite + Graphite
Brand: 
Interested in this product?
Cotton- and phenolic resin-based laminates with graphite
Excellent workability with low friction coefficient
Ideal for the manufacture of pump vanes, bushings, and bearings
The graphite in the product makes it a self-lubricating material and enhances the durability of parts that are made with it.
It is available in sheets of the following sizes: 1000x1500 mm, 1200x2200 mm, 1050x2050 mm.
