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.

Product Mean Particle Size (µm) Specific Gravity Cone Penetration
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

Food Grade (NSF) PTFE

Products recommended for food grade use according to NSF:

Product Mean Particle Size (µm) Cone Penetration
Method ISO 13320 ASTM D217
Fluoro GE 100-RC < 1 µm 220-280 1/10mm
Fluoro GS 115-RC 4-6 µm 320-400 1/10mm
Fluoro GS 125-RC 10-15 µm 335-415 1/10mm
