Material Introduction

PCTFE is a semicrystalline fluoropolymer synthesized via free-radical polymerization of  CTFE monomers. Launched in the mid-20th century, it integrates PTFE's extreme chemical resistance with enginee 

•Chemical Resistance: Near-inert to concentrated acids, alkalis, solvents, and corrosives (except molten alkali metals/fluorinating agents), outperforming PTFE in aromatic hydrocarbons.

•Barrier Performance: Ultra-low permeability ( 0.01 cm³·mm/(m²·day·atm); water vapor: 0.005 g·mm/(m²·day))—ideal for hermetic protection. •Mechanical & Thermal Stability: Tensile strength 35–45 MPa, retains 80% strength at -100°C, flexible down to -200°C; operates -200°C to 120°C (short-term 150°C) with minimal creep.

•Safety & Compliance: UL94 V-0 non-flammable (LOI 65%), FDA/ISO 10993 biocompatible, compatible with autoclaving/EtO sterilization.

•Electrical Insulation: Dielectric constant 2.3–2.5 (1 MHz), dielectric strength 20–25 kV/mm—stable across temp/frequency ranges. Processing Methods Processable via injection molding (230–260°C), extrusion (films/tubes), machining (precision parts), and compression molding (thick components), with controlled cooling to avoid shrinkage. Key Applications •Aerospace: Seals, wire insulation, satellite electronics packaging (resists jet fuels/vacuum). •Medical: Sterilizable components, drug blister packs, implantable devices (biocompatible). •Chemical Processing: Valve liners, tank liners, semiconductor etching chamber parts (corrosion-resistant). •Electronics: PCB moisture barriers, high-frequency connectors (low permeability/dielectric stability). •Cryogenics: Liquid gas handling valves/gaskets (retains flexibility at -200°C). Competitive Advantages Vs. PTFE: Higher rigidity/creep resistance; vs. PFA/FEP: Superior barrier performance; vs. engineering plastics: Extreme chemical/thermal stability. Ideal for high-stakes environments demanding reliability.
