Product Description

What is Fiberglass Filled PTFE Rod?

Fiberglass filled PTFE rod is made of PTFE powder mixed with 3% to 25% glass fiber, so fiberglass filled PTFE rod has enhanced strength, the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE products. Addition of fiberglass improves compressive properties by as much as 25%.

Why We Use Fiberglass Filled PTFE Rod?

The reason why we use fiberglass filled ptfe rod is that it has extremely good chemical resistance, good sliding properties, improved dimensional stability and enhanced creep resistance. Fiberglass filled PTFE rod also has very good electrical insulation properties.

Applications of Fiberglass Filled PTFE Rod

Fiberglass filled PTFE rod can be used for pump housings, valve seats, gaskets, roller coverings, shaft bearings, filter housings, etching plates, shaft seals, slide runners, chemical engineering, machine parts, transport and conveyor technology, pump and instrument construction, electrical industry, electronics, laser technology, fume purification, pure water production, cryogenics, filter technology, food and medical technology.

Fiberglass Filled PTFE vs Virgin PTFE

Virgin PTFE or pure PTFE has a range of benefits. One small area of weakness though is that its propensity to experience creep at low and high temperatures when being used for sealing. Adding fiberglass mixed with PTFE helps alleviate this.

The fiberglass in PTFE also increases the materials capacity to withstand wear and friction over time.

Of course, adding fiberglass with PTFE changes the properties of the PTFE material. Fortunately, there are only a few drawbacks. Chemical resistance is still outstanding, though fiberglass filled PTFE should not be exposed to fluoridric acid.

Some mechanical properties also change with the largest impact experienced in tensile strength. This drops from about 20 mpa for Virgin PTFE to 13 mpa for 25% fiberglass Filled PTFE. Most other attributes, including UV Resistance, temperature resistance and dielectric strength are largely unaffected or only nominally so.
