PTFE Tubing for Chemical Processing: Applications, Benefits and Specifications
PTFE Tubing for Chemical Processing
Yash Dynamics manufactures PTFE fine-powder extruded tubing using vertical paste extrusion technology. PTFE tubing provides a hollow fluoropolymer path for fluid handling and can also serve as protective sleeving. Dimensions and operating requirements are selected for the intended application.
Why Choose PTFE Tubing?
PTFE is valued for its chemical inertness, lubricity and dielectric properties. In tubing form, these material properties support chemical handling, low-friction surfaces and electrical insulation.
- Chemical resistance for demanding process environments.
- A low-friction, non-stick inner surface.
- Dimensions selected for the required fluid path or protective sleeve.
- Continuous-length or cut-to-length supply.
Published Tube and Liner Dimensions
Tube and liner outside diameter: 1.00–6.00 mm. Wall thickness: 0.20–1.00 mm. Inner diameter, dimensional tolerances and custom sizes are confirmed against the application specification.
Nominal PTFE Tubing Properties
| Property | Nominal value | Standard |
|---|---|---|
| Minimum working temperature | −270°C | Nominal |
| Maximum working temperature | +260°C | Nominal |
| Specific gravity | 2.14–2.19 | ASTM D792 |
| Ultimate tensile strength at 23°C | 14–34 MPa | ASTM D638 |
| Elongation at break at 23°C | 200–500% | ASTM D638 |
| Concentricity | ≥85% | Nominal |
| Hardness | 50–65 | Shore D |
| Melting point | 327°C | Nominal |
Nominal values vary with tube sizes and resin properties and do not constitute a warranty. Confirm final requirements for the application.
Chemical-Processing Applications
The brochure identifies PTFE as a suitable substitute for glass because of its inertness and durability. Chemical transfer, analytical equipment and protective sleeving requirements should be reviewed against the fluid, temperature, dimensions and installation conditions.
Material Compliance
The brochure lists PTFE fine-powder compliance with FDA 21 CFR 177.1550, EU Regulation No. 1935/2004, EC Regulation No. 1895/2005, RoHS Directive 2011/65/EU, REACH compliant, USP Class VI, PFOA free. Confirm the supporting documentation and application requirements with our technical team.
Supply Options
Tubing is available in continuous lengths or cut to length. Natural is the standard colour; other colours are available on demand. Custom sizes and specifications can be discussed for the application.
Specifying PTFE Tubing
Share the required OD, ID, wall thickness, dimensional tolerances, length, fluid, operating temperature and pressure, connection requirements and quantity. Pressure capability and installation details must be confirmed for the selected tubing specification.
Frequently Asked Questions
