490 µm

Average Particle Diameter

680 g/L

Ultra-High Bulk Density

6,000 psi

Tensile Strength (41.4 MPa)

Type IV / Gr. 1

ASTM D4894 Standard

Optimized flowability. Flawless surface finish.

Everflon™ PTFE Granular Free Flow is engineered to deliver superior cavity fill, enhanced moldability at reduced compaction pressure, and consistent finish.

💧

Exceptional Free-Flow Characteristics

High bulk density (680 g/L) and larger particle sizing ensure smooth, uniform die filling and consistent flow in complex mold geometries.

🔄

Lower-Pressure Moldability

Unique resin rheology enables effective preforming under reduced hydraulic pressures while maintaining high mechanical strength and dimensional stability.

✨

Superior Surface Smoothness

Minimizes surface irregularities in thick molded sheets, isostatic components, and ram-extruded profiles, reducing post-machining cycle times.

🛡️

Universal Chemical & Thermal Shield

Total inertness to corrosive chemicals, lowest friction coefficient, and broad continuous service range from cryogenic to 260 °C (500 °F).

Application Versatility

Built for heavy-duty molding and extrusion.

Valve Components & Seats

Ball valve seats, valve plugs, discs, and high-integrity fluid seals for severe chemical service.

Thick Molded Sheets & Stock Shapes

Compression molded heavy sheets, thick billets, and stock blocks engineered for precision CNC machining.

Ram Extrusion Rod & Tubing

Continuous ram-extruded thick-cross-section rods, heavy-wall tubes, and structural profiles.

Corrosion & Chemical Linings

Pipe linings, expansion bellows, ducting, piston rings, and high-purity laboratory ware.

Processing Parameters & Handling

01 / Isostatic Molding & Extrusion

Compaction & Sintering

Optimized for isostatic pressing of thick sheets and continuous ram extrusion of rods and tubing. Cold compacted, then consolidated through precise sintering above 342 °C.

02 / Storage Temperature

21–27 °C (70–80 °F)

Condition powder uniformly within the 21–27 °C window prior to molding to preserve free-flow behavior, eliminate agglomeration, and prevent moisture compaction defects.

03 / Packaging & Compliance

FDA & Standard Drums

Meets FDA 21 CFR 177.1550 and EU 10/2011 requirements for food contact. Supplied in clean 40-kg (88-lb) heavy-duty drums with protective polyethylene liners.
