What is PTFE dispersion?

PTFE dispersion is a colloidal suspension of polytetrafluoroethylene (PTFE) particles in water or other liquid media. It retains the exceptional properties of solid PTFE—chemical resistance, high-temperature stability, and low friction—while being easier to apply as a coating or additive in industrial processes.

What are the key physical properties of Symb ChemTech's PTFE dispersions?

Symb ChemTech's PTFE dispersions are white or yellowish liquids with a solid content of 60 ± 2%, a surfactant level of 3.0–8.0% depending on the grade, a pH range of 8–10, and a viscosity between 10 and 100 × 10⁻³ Pa·s depending on the specific grade.

What grades of PTFE dispersion does Symb ChemTech offer?

Symb ChemTech offers six grades of PTFE dispersion: JF-4DCW, JF-4DCM, JF-4DCD, JF-4DCB, JF-4DCF, and JF-4DCT. Each grade is tailored for specific performance requirements, with slight variations in surfactant content and viscosity.

What are the main applications of PTFE dispersion?

PTFE dispersion is widely used for glass fiber and asbestos impregnation to enhance strength and durability, for creating high-grade non-stick coatings on various surfaces, and as an effective anti-flaming agent in plastic formulations to improve fire resistance.

How is PTFE dispersion packaged and stored?

Symb ChemTech's PTFE dispersions are typically packaged in 25 kg and 1000 kg drums. For optimal stability, avoid heavy shaking, high temperatures, and freezing during transportation and storage. After three months of storage, regular shaking of the drums is recommended to prevent deposition.

Can PTFE dispersion be used as a non-stick coating?

Yes, PTFE dispersion is ideal for creating high-grade non-stick coatings on various surfaces. It offers excellent release properties and strong resistance to abrasion, making it a preferred choice for cookware, industrial molds, and other applications where release performance is critical.

What is the viscosity range of Symb ChemTech's PTFE dispersions?

The viscosity of Symb ChemTech's PTFE dispersions varies by grade: JF-4DCW ranges from 10–75 × 10⁻³ Pa·s, JF-4DCM and JF-4DCD range from 15–40 × 10⁻³ Pa·s, JF-4DCF ranges from 10–100 × 10⁻³ Pa·s, and JF-4DCT ranges from 15–75 × 10⁻³ Pa·s.

What is the surfactant content in Symb ChemTech's PTFE dispersions?

The surfactant content varies by grade: JF-4DCW has 3.0–7.0%, JF-4DCM and JF-4DCD have 4.0–7.5%, JF-4DCB has 5.0–8.0%, JF-4DCF has 4.0–7.5%, and JF-4DCT has 4.0–7.0%.

What makes PTFE dispersion suitable as an anti-flaming agent?

PTFE dispersion serves as an effective anti-flaming agent in plastic formulations by improving the fire resistance of the material. When incorporated into polymer matrices, the PTFE particles help reduce flammability and slow flame propagation, contributing to safer end products.
