Ekonol® Aromatic Polyester

Ekonol® aromatic polyester fillers are a key component in extending the life of parts & components made from PTFE compounds. The exceptional properties of Ekonol PTFE fillers provide maximum wear resistance, dimensional stability & corrosion resistance for molded or extruded parts in demanding services. It is primarily used in PTFE compounds for bearings and seals applications.

Features & Benefits:

  • Highly crystalline structure, allowing thermal stability
  • Good creep resistance & excellent load-bearing capacity
  • Round shape which does not wear metal surfaces (especially rotating parts)
  • Good lubricity
  • Chemical resistance (except to sulfuric acid and strong alkalis)
Ekonol

Saint-Gobain varies particle size distribution & apparent density to deliver two grades of Ekonol polyester PTFE fillers. Our team can work with you to select the proper grade of Ekonol PTFE filler to meet your specific application needs.

T101

Ekonol® T101 Polyester PTFE Filler for Bearing Applications

T101 Ekonol(R)

Ekonol® T101 aromatic polyester filler is a tan powder additive that, when combined with PTFE, produces a composite material with excellent temperature and wear resistance for a wide range of mating surfaces in demanding services. This filler extends the life of bearings and other large moving parts that may contain silica or alumina.

The highly crystalline structure of the Ekonol® T101 polymer was created to deliver maximum dimensional, chemical & thermal stability. In addition, the non-abrasive character of Ekonol® T101 polyester enhances the frictional performance to prevent galling of softer mating surfaces better than other PTFE fillers.

M102A

Ekonol® M102A Polyester PTFE Filler for Seal Applications

Ekonol M102

Ekonol M102A aromatic polyester filler is a light tan/white powder additive that, when combined with PTFE, produces composite materials with excellent temperature and wear resistance for a wide range of mating surfaces in demanding services.

Saint-Gobain M102A is a polyester powder comprised of smaller particle sizes that are ideal for thinner products such as seals. When added to PTFE, Ekonol M102A filler imparts maximum dimensional, chemical & thermal stability. In addition, the non-abrasive character of Ekonol M102A filler enhances the frictional performance to prevent galling of softer mating surfaces better than other PTFE filler.
