Premium FEP Particle For Cable Insulation And Sheathing (Model: HD921)

Premium FEP Particle for Cable Insulation & Sheathing: Heat Stress Cracking Resistant, Excellent Dielectric & Chemical Resistance. Ideal for Oil-Gas, Defense, Aviation Cable Manufacturing.

FEP (Fluorinated Ethylene Propylene) Particle for Cable Insulation and Sheathing refers to high-purity translucent fluoropolymer particles specifically engineered for manufacturing cable insulation layers and sheathing. As a copolymer of hexafluoropropylene and tetrafluoroethylene, it belongs to the high-performance fluoropolymers family, sharing core properties with PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin) while featuring superior melt-processability. Our HD921 model FEP particle is a heat stress cracking resistant plastic, tailored for cable production with a controlled melt flow rate (2.1~5.0 g/10min) and excellent mechanical/chemical stability. It provides reliable insulation and protection for cables in harsh environments, making it a preferred material in oil, gas, petrochemical, defense, and aviation industries.

HD921 FEP particle integrates multiple superior properties tailored to meet the strict requirements of cable insulation and sheathing, each property addressing core pain points of cable manufacturers and end-users:
● Heat Stress Cracking Resistance: As a dedicated heat stress cracking resistant plastic, HD921 FEP particle maintains structural integrity even under long-term thermal cycling and mechanical stress. This prevents cracking of cable insulation/sheathing in high-temperature working environments, ensuring long-term cable operation stability.
● Exceptional Dielectric Properties: It exhibits a low dielectric constant (≤2.15 at 10⁶ HZ) and low dissipation factor (≤7.0×10⁻⁴ at 10⁶ HZ), minimizing signal interference and ensuring efficient electrical insulation. This makes it ideal for high-frequency communication cables and precision electronic wires.
● Wide Operational Temperature Range: HD921 FEP particle operates stably in a temperature range of -200℃ to 200℃, with a melting point around 270℃. It maintains consistent performance in extreme cold (e.g., polar regions) and high-heat (e.g., industrial furnaces nearby) environments, expanding cable application scenarios.
● Excellent Resistance to Chemicals, UV and Corrosion: The stable C-F bonds make it inert to most industrial chemicals, strong acids, alkalis, solvents, and moisture. It also has outstanding UV resistance, preventing aging and degradation caused by long-term outdoor exposure. These properties are critical for cables used in oil, gas, petrochemical, and offshore environments.
● Flexibility and Durability: With a tensile strength of ≥26 MPa and an elongation at break of ≥320%, HD921 FEP particle offers excellent toughness and flexibility. Cable insulation/sheathing made from it can effectively protect internal wires, maintain high-level functionality, and withstand mechanical impacts, abrasion, and bending during installation and use.
● Non-Stick and Low Friction: Similar to other fluoropolymers, it has a low friction coefficient and non-stick characteristics. This reduces friction between cables and conduits during installation, improving construction efficiency, and prevents dust, dirt, and moisture adhesion, reducing maintenance costs.
● Flame and Heat Resistance: It is inherently non-ignitable and can stop flame spread, meeting UL94 V-0 flammability standards. This minimizes fire risks, making it suitable for cables in high-risk environments such as defense equipment, aviation vehicles, and industrial plants.
● Environmentally Friendly and Recyclable: HD921 FEP particle complies with modern environmental protection requirements, being recyclable and free of harmful substances. It reduces environmental impact during production and disposal, aligning with global sustainability trends.
● Low Volatile Content: With a volatile content of ≤0.1%, it emits minimal gas during processing and use. This avoids contamination of sensitive components in sealed environments such as aviation cabins and electronic enclosures.
