Product Brief
High-Crystallinity PTFE Fine Powder HD9203F: Ideal for Paste Extrusion. Enables Continuous Tapes/Tubes/Fibers, Excellent Chemical Inertness for Multi-Industry Applications.
Product Overview
High-Crystallinity PTFE Fine Powder Resin (Model: HD9203F) is a premium white polytetrafluoroethylene (PTFE) fine powder produced via emulsion polymerization. As a high-molecular-weight, highly crystalline fluoropolymer, it is specifically engineered for paste extrusion processing, enabling the fabrication of continuous-length PTFE products such as tapes, tubes, elastic bands, membranes, and fibers. Known as the "King of Plastics," PTFE boasts unparalleled chemical inertness, thermal stability, and low friction properties, and HD9203F inherits these core advantages while maintaining optimized processability for paste extrusion. Compliant with global quality standards, this resin serves as a reliable material solution for chemical, pharmaceutical, medical, automotive, and high-performance wire cable industries.
Product Details
What is HD9203F PTFE Fine Powder Resin?
Polytetrafluoroethylene (PTFE) is a linear fluoropolymer synthesized by the polymerization of tetrafluoroethylene (TFE) monomers. PTFE fine powder, typically produced via emulsion or dispersion polymerization, is distinguished by its fine particle size and suitability for paste extrusion-a critical processing method for manufacturing continuous PTFE products. Our HD9203F PTFE fine powder is manufactured through precision emulsion polymerization, where controlled surfactant addition and mild agitation under elevated temperature and pressure ensure uniform particle size (400-575μm) and high crystallinity.
Unlike other PTFE grades (e.g., molding powder) or fluoropolymers like FEP and PVDF, HD9203F's unique advantage lies in its tailored properties for paste extrusion: it maintains stable flowability under extrusion pressure (30-45 Mpa at 400:1 compression ratio), enabling the production of consistent, continuous-length articles without structural defects. Its high crystallinity (crystal form transition at 19℃) ensures that extruded products retain excellent mechanical strength and thermal stability, outperforming FEP in high-temperature resistance (melting point 327±5℃ vs. FEP's 260±5℃) and surpassing PVDF in chemical inertness to aggressive media.
Key Properties of HD9203F PTFE Fine Powder Resin
HD9203F's properties are precisely optimized for paste extrusion and multi-industry application demands, supported by scientific principles and verified technical data:
● Superior Chemical Inertness: Inert to nearly all industrial chemicals, including strong acids (98% sulfuric acid), strong bases (50% sodium hydroxide), organic solvents, and oxidants. The high bond energy of C-F bonds (485 kJ/mol) in its molecular structure prevents chemical reactions, ensuring extruded products maintain integrity in harsh chemical environments-critical for chemical processing and pharmaceutical fluid handling applications.
● Optimized for Paste Extrusion: With an average particle size of 400-575μm and volume density of 475±100 g/l, it exhibits excellent paste flowability. It performs stably under extrusion pressure of 30-45 Mpa (400:1 compression ratio), enabling the production of continuous-length products with uniform thickness and smooth surfaces. The maximum compression ratio of 400 further expands its processing flexibility for diverse product specifications.
● High Crystallinity & Mechanical Strength: As a highly crystalline PTFE grade, it offers a tensile strength of ≥25 MPa and elongation at rupture of ≥320%, ensuring extruded products (e.g., tapes, fibers) have excellent toughness and durability. Its crystal form transitions at 19℃-above this temperature, it becomes softer for easy deformation during processing, while retaining rigidity and stability in end-use environments.
● Excellent Thermal Stability: With a melting point of 327±5℃, it maintains stable properties at continuous operating temperatures up to 260℃ and can withstand short-term exposure to 300℃. This thermal stability surpasses most fluoropolymers like ETFE and PVDF, making it suitable for high-temperature applications such as automotive underhood components and industrial high-temperature gaskets.
● Low Friction & Non-Stick Properties: It has an ultra-low friction coefficient (≤0.04), ensuring extruded products have excellent non-stick and wear-resistant performance. This makes it ideal for manufacturing non-stick tapes and low-wear mechanical components, reducing friction-induced damage and extending service life.
● High Purity & Low Moisture: With a moisture content of ≤0.03% and Grade A quality, it meets the high-purity requirements of pharmaceutical and medical industries. It does not leach harmful substances, ensuring safety for food contact and medical device applications.
