Product Overview

I. Material Definition
Our PCTFE Homopolymer Resin is a premium fluoropolymer synthesized via controlled polymerization of chlorotrifluoroethylene monomers. Its unique molecular structure—a carbon backbone substituted with fluorine and chlorine atoms—confers exceptional resistance to cryogenic temperatures, aggressive chemicals, and mechanical stress.

Designed for industries requiring absolute reliability (e.g., aerospace, energy, pharmaceuticals), this material integrates thermal stability (-273°C to 213°C), chemical inertness, and optical clarity, making it ideal for critical seals, laser components, and electrical systems.

Key Properties

II. Technical Specifications

  1. Cryogenic Performance
    • Operates continuously at liquid nitrogen temperatures (-196°C)
    • No embrittlement or creep at -273°C (approaching absolute zero)
  2. Chemical Resistance
    • Withstands 98% H₂SO₄, 50% NaOH, aromatic hydrocarbons, and chlorinated solvents
    • Suitable for CFC oil storage, acid/alkali transfer systems, and pharmaceutical reactors
  3. Mechanical Strength
    • Tensile strength: 45 MPa (3× higher than PTFE)
    • Shore D hardness: 85 (60% greater than PTFE)
    • Resists dynamic stresses in vibrating equipment
  4. Optical & Electrical Performance
    • Light transmission: >92% (3mm sheet) with <2% haze
    • Volume resistivity: 1.2×10¹⁷ Ω·cm (humid environments)
    • UV stability (λ>300nm transmission >85%)
  5. Low Compression Set
    • Permanent deformation <5% under prolonged compression
    • Ensures long-term sealing reliability in static/dynamic applications

Applications

III. Industry-Specific Uses

  1. Cryogenic Engineering
    • Seals for LNG valves, liquid oxygen storage tanks, and rocket fuel systems
    • Gaskets in cryogenic pumps (-253°C to 200°C)
  2. Optical & Precision Instruments
    • Transparent viewports for cryogenic cell culture systems
    • Laser system windows (350–2500nm compatibility)
  3. Electrical & Electronics
    • Humid-environment connectors (IP68 rated)
    • High-frequency PCB substrates (dielectric constant: 2.1)
  4. Chemical Processing
    • Reactor linings for CFC oil storage
    • Diaphragms in chemical pumps handling 98% H₂SO₄

Processing Guidelines

IV. Manufacturing Recommendations

  1. Molding Methods
    • Injection Molding: For complex geometries (mold temp: 180–220°C)
    • Compression Molding: For thick-section parts (pressure: 10–20 MPa)
  2. Critical Parameters
    • Curing: Post-mold annealing at 200–250°C for 4–8 hours
    • Drying: Pre-drying at 80°C for 4 hours (moisture absorption <0.01%)
    • Tooling: Chrome-plated molds recommended to prevent adhesion

Storage & Handling

V. Safety & Maintenance

  1. Storage Conditions
    • Temperature: <25°C (ideal: 15–20°C)
    • Humidity: <60% RH
    • Avoid direct sunlight and strong oxidizers
  2. Safety Precautions
    • Wear nitrile gloves and safety goggles during handling
    • Use dust extraction systems to minimize inhalation
    • Follow EPA TSCA (CAS 9002-83-9) disposal regulations

Why Choose Our PCTFE?

VI. Competitive Advantages

  1. 20-Year Fluoropolymer Expertise: Vertically integrated production from monomer to finished product
  2. Custom Formulations: Conductivity-enhanced grades (10⁻⁴ S/m) and UV-stabilized variants available
  3. Global Compliance: Pre-registered under EU REACH, RoHS-compliant
