Regulatory Compliant PTFE Products for Greases and Lubricants
Shamrock offers a range of Regulatory Compliant (RC) PTFE micropowders made from Natural prime and Recycled raw materials.
Shamrock RC PTFE products are produced to be in compliance with the Commission Delegated Regulation (EU) 2020/784 amending Annex I to POPs Regulation (EU) 2019/1021 (per Shamrock QSOP-202E). To best support our customers during the transition period, both EU Regulatory compliant and standard grades will continue to be globally available.
Addendum:
The EU has added C9-C14 PFCAs and C9-C14 PFCA-related substances under ANNEX XVII of REACH. The new law will become effective on February 25, 2023.
On August 5, 2021, the European Union (EU) published Regulation (EU) 2021/1297 to replace entry 68 to Annex XVII of Regulation (EC) 1907/2006 on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH, consolidated version to July 2021) in relation to ‘Restrictions on the manufacturing, placing on the market and use of certain dangerous substances, mixtures and articles.’
Natural Prime for PTFE Greases & Lubricants
Fluoro GE
Fluoro GE sub-micron PTFE are powders made from emulsion grade Natural Prime PTFE. These products cover a range of molecular weights to determine dispersability, thickening and performance properties. Due to the small particle size, the GE products have a larger specific surface area when compared to other PTFE.
| Product | Mean Particle Size (µm) | Cone Penetration | 4 Ball Wear Scar | Bulk Density |
|---|---|---|---|---|
| Method | ISO 13320 | ASTM D217 | ASTM D2266 | ASTM D4894 |
| Fluoro GE 100-RC | < 1 µm | 250-280 1/10mm | ||
| Fluoro GE 125-RC | < 1 µm | 230-280 1/10mm | 0.40-0.50 | 200-350 g/l |
| Fluoro GE 150-RC | < 1 µm | 250-290 1/10mm | 0.30-0.40 | 200-400 g/l |
Fluoro GS
Fluoro GS powders are made from unsintered, suspension grade Natural Prime PTFE. These products are characterized by the uniform, crystalline structure of PTFE provide increased slip and abrasion properties.

| Method | ISO 13320 | ASTM D2320 | ASTM D217 | ||
| Fluoro GS 100-RC | 3.5-6 µm | – | 355-430 1/10mm | ||
| Fluoro GS 115-RC | 4-6 µm | 2.15 | 320-400 1/10mm | ||
| Fluoro GS 125-RC | 10-15 µm | 2.15 | 335-415 1/10mm |
Recycled PTFE for Greases & Lubricants
Fluoro GT
Fluoro GT PTFE micro powders are made from highly crystalline, sintered PTFE. These products can be added with minimal to no change to the viscosity of the system. They impart excellent lubricity and wear resistance.
| Product | Mean Particle Size (µm) | Cone Penetration | Bulk Density |
|---|---|---|---|
| Method | ISO 13320 | ASTM D217 | ASTM D4894 |
| Fluoro GT 105-RC | 5 µm | 370-460 1/10mm | 400-600 g/l |
| Fluoro GT 130-RC | 25-35 µm | >475 1/10mm | 500-800 g/l |
