PTFE compound

The wide range of peculiar PTFE properties can be further enlarge with the addition of inorganic and polymeric fillers, increasing compressive strenght and wear resistance.

Type and quantity of fillers added change with the final application and define the properties requested.
The most used families of inorganic fillers are: carbon, bronze, graphite, glass, molybdenum disulfide, mica.
The polymeric fillers are selected among technopolymers that guarantee similar or higher thermal stability than PTFE. The most widely used polymers are: polyimides, aromatic polyesters, PAI, PPS, PEEK.

Drawing on thirty years of experience, POLIS is able to guarantee and optimise the properties of the compounds it produces through the selection of PTFE, fillers, specific treatments, mixing techniques and post-processing of the mixtures.

In order to optimize the customer's transformation processes, guaranteeing the best physical and mechanical properties, the great majority of POLIS compounds are available in the following versions:

NFF for classic compression molding of large and medium pieces
FF for classic, automatic and isostatic compression molding
FF HDS for automatic molding and ram extrusion
E / EH for ram extrusion
In addition to the products in its portfolio, POLIS works with customers to develop and optimise compounds, with a view to meeting the global market’s demand for increasingly specialised performance.
