Product Benefits
Thermal performance
The PFA reference heat-resistance value is 260°C. Confirm the permitted temperature of the finished component or joint together with mechanical load and the full assembly.
Химическая стабильность
PFA provides chemical and corrosion resistance, including resistance to alkalis and sulfuric acid in the reference description. Define concentration, temperature and exposure time for the selected application.
Mechanical and electrical properties
The reference identifies mechanical performance, insulation, lubricity and resistance to bending and cracking. Required properties and test methods must be agreed for the supplied grade and finished part.
Low absorption and surface behavior
The material offers low water absorption and a nonstick surface, together with aging and UV resistance. Confirm any numerical absorption or weathering acceptance limit for the selected grade.
Complete Physical and Mechanical Data
| Недвижимость | Unit | Reference value |
| Heat resistance reference | °C | 260 |
| Плотность | g/cm³ | 2.12-2.17 |
| Прочность на разрыв | MPa | ≥15 |
| Удлинение при разрыве | % | ≥250 |
| Твердость | Shore D | Approximately 55 |
| Dielectric breakdown strength | kV/mm | ≥50 |
These are material reference values, not guaranteed limits for every finished rod, welding joint or production lot. Confirm specimen condition, test methods and order acceptance criteria. kV/mm describes dielectric breakdown strength rather than an absolute voltage rating.
Complete Size and Supply Table
| Product form | Размер | Length or dimensional note |
| Extruded rod | Diameter 10-165 mm | Length 100-1000 mm |
| Molded rod | Diameter 6-135 mm | Length <200 mm |
| Round welding rod | Diameter 3-5 mm | 20 m or 100 m |
| Flat welding strip | 12 × 2.5; 14 × 2.5; 17 × 2.5 mm | Width × thickness; length to confirm |
The flat-strip row is identified by its Chinese description and width × thickness values. The source English row labels it a round welding rod. The 20 m and 100 m entries are welding-rod supply lengths, rather than millimeter values implied by the general table heading.
PFA Rod Applications
Rod stock can be reviewed for corrosion-resistant parts, seals, vibration-reduction parts, insulation components, anti-adhesion parts, transparent parts and capacitor-related insulation. Listed examples include corrosion-resistant pump parts, valve and piping components, precision seals, high-temperature sealing components, wear parts and medically related equipment parts. Define the grade and any qualification required for the actual application.
PFA Welding Material Applications
Round rods and flat strips are listed for welding and processing fluoropolymer equipment, piping and parts used in anti-corrosion equipment, chemical plants and semiconductor equipment. The catalog refers to processing PTFE products; confirm the actual substrate and a qualified PFA joining method before selecting welding material. A weld should not be assumed solely from the material names.
Custom Supply and Inspection
Send rod form, diameter or strip width and thickness, length, quantity and tolerances. For machining, include the finished drawing and material requirements. For joining, identify the substrate, joint design, welding procedure and required inspection. Agree dimensions, surface condition, material records and required mechanical or electrical tests.
Frequently Asked Questions
Which PFA forms are listed
Extruded rod, molded rod, round welding rod and flat welding strip are listed, with all sizes and reference lengths shown above.
Can the 260 degree value be used as a joint rating
The 260°C value is a material heat-resistance reference. A machined component or joint requires its own confirmed limits under the actual load and service conditions.
Can you supply custom dimensions
Custom sizes, lengths and tolerances can be reviewed against a drawing. Confirm the production route and supply form with the quotation.
