SUSTADUR® TF is a bearing grade polyester providing enhanced wear and inertness over general purpose nylon (PA) and acetal (POM) products. Containing uniformly dispersed solid lubricant, SUSTADUR® TF provides a lower wear rate and coefficient of friction than unmodified polyesters like PET or PBT.
SUSTADUR® TF excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces.
- No stick-slip
- Low friction and wear
- Self lubricating
- High strength and stiffness
- High dimensional stability
- Improved performance and longer life
- EU and FDA approved for food applications
TEMPERATURE RANGE
| SUSTADUR® | SUSTADUR TF® | |
| Max service temperature for short periods | 180 ºC | 180 ºC |
| Max service temperature continuously | 115 ºC | 115 ºC |
| Min service temperature | -20 ºC | -20 ºC |
Sliding elements, gears, bearings, bushes and cams
SUSTADUR® Polyethylene Terephthalate (PET) has high mechanical strength, good resistance to creep, excellent dimensional stability and excellent sliding properties. SUSTADUR® (PET) has superior wear resistance compared to acetal and is ideal for close tolerance parts.
Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture making this material ideally suited as a bronze bush replacement. SUSTADUR® PET-P can be machined to precise detail on standard metal working equipment.
- Improved tensile strength
- Good for both wet and dry environments
- High strength and rigidity––ideal for close tolerance parts
- Excellent stain resistance
- Good wear resistance and excellent dimensional stability
- Better resistance to acids than nylon or acetal
- Better operating temperature
- Reduced notched impact resistance
- SUSTADUR® is FDA approved.

For high-grade and high-strength technical parts in many industrial sectors like e.g. mechanical engineering, electronic industry, ship building industry, materials handling industry, food processing industry etc.
General mechanical and plant engineering: e.g. gears, levers, handles, control discs, cams, bearings, sliding elements, bearings, door furniture, hinges, food industry
NOTE: Although it absorbs very little moisture SUSTADUR® does suffer from hydrolysis and should not be used in aqueous applications at temperatures above 70º C or steam environments.
