STEMEFLON PTFE 25gl
25% glass filled polytetrafluoroethylene (P.T.F.E.)

Material characteristics

Addition of glass improves mechanical properties and wear resistance, while has the least effect on chemical and electrical properties. In comparison with virgin PTFE, low chemical resistance to alkalis and increased coefficient of friction. Very low absorption of moisture, very high service temperature, excellent sliding properties, very good electrical properties, low mechanical strength, high density.

Supply programme

  • Rods (bars), Ø20 to Ø250 diameter, in standard length of 2000/1000/300 mm, ivory color

  • Hollow bars (tubes), Ø50x20 to Ø250x150 outer diameter x inner diameter, in standard length of 300 mm, ivory color

 

STEMEFLON PTFE 20gl5gr
20% glass filled & 5% graphite filled polytetrafluoroethylene (P.T.F.E.)

Material characteristics

Addition of glass improves mechanical properties and wear resistance, while has the least effect on chemical and electrical properties. In comparison with virgin PTFE, low chemical resistance to alkalis and increased coefficient of friction. Addition of graphite mainly improves the lubricity. Very low absorption of moisture, very high service temperature, excellent sliding properties, good electrical properties, low mechanical strength, high density.

Supply programme

  • Rods (bars), Ø20 to Ø250 diameter, in standard length of 300 mm, black color

  • Hollow bars (tubes), Ø50x20 to Ø250x150 outer diameter x inner diameter, in standard length of 300 mm, black color

 

STEMEFLON PTFE 60br
60% bronze filled polytetrafluoroethylene (P.T.F.E.)

Material characteristics

Addition of bronze improves mechanical properties and thermal conductivity, while maximizes wear and deformation resistance. In comparison with virgin PTFE, low chemical resistance, moderate electrical properties and increased coefficient of friction. Very low absorption of moisture, very high service temperature, high density.

Product data sheet

Application examples

Bearing bushes, bearings at high speeds, sealing rings, piston rings, sliding surfaces.

Supply programme

  • Rods (bars), Ø20 to Ø250 diameter, in standard length of 300 mm, brown color

  • Hollow bars (tubes), Ø50x20 to Ø250x150 outer diameter x inner diameter, in standard length of 300 mm, brown color
