Product compounds
P.T.F.E. is comparatively soft thermoplastic with some excellent properties like chemical inertness and low coefficient of friction.

In adding fillers properties like hardness, resistance to wear and deformation, electrical and thermal conductivity can be changed.

 UPM's compound division produces over a hundred types of compound ranging in quantity from a few kilogram's to a few tonnes annually.

The matrix material for these compound is mainly purchased from the well established PTFE producers in the world like Du Pont and Asahi etc.

Filler percentage can vary from 0,1 to 75% the only limitation being that the filler must be able to withstand the prolonged sintering temperature of PTFE of 380 degrees. Filler types are pigments of anorganic nature, glass fibres, bronze, graphite, carbon, calcium fluoride in single form or combination.

Almost every compound can be made in three different FORMS:

NFF (Non Free Flow)

This powder shape is used for hand filling of moulds with considerable wall thickness. If compared with Free Flow or Extrusion grades with the same composition the properties of a NFF are better.

Billets from 0,1 to 360kg can be made.

FF (Free Flow)

Used for hand filling or automatic moulding. The flow and bulk density are properties wherefore U.P.M. still develops new methods to improve.
E (Extrusion grade)

Not suitable for free sintering, only suitable for automatic moulding. Also Extrusion grades can be made in all different types of compositions.
