Product Details
The core parameters of PTFE sodium film are as follows: physical properties Thickness: Usually between 10-50 microns, some products can reach up to 300 millimeters (such as Huafu Company''s products). Porosity: controlled at 30% -60%, balancing ion transport and mechanical strength. Tensile strength: ≥ 15MPa, some products can meet the injection grade wear-resistant standard. Friction coefficient: The double-sided smooth design has a friction coefficient of approximately 0.11. chemical PROPERTIES Temperature resistance range: It can be used stably in environments ranging from -200 ℃ to 260 ℃. Corrosion resistance: resistant to acid and alkali corrosion, with a contact angle of up to 114 ° -115 °, and excellent waterproof and moisture-proof performance. Electrical Characteristics Volume resistivity: ≥ 1 × 10 ¹⁵Ω· m, with outstanding insulation performance. Conductivity: After sodium treatment, the conductivity can reach the level of 10 ⁻ s/cm. Some products can increase conductivity by 15% -20% through a two-step ion implantation process. Application scenarios Industrial applications: petrochemical, aerospace communication, electronic and electrical fields, etc. Electronic components: flexible pressure sensors, flexible circuit boards (capable of withstanding 100000 180 ° bends with a resistance change rate of less than 3%). New energy: Sodium ion battery separator (capacity retention rate>85% after 1000 cycles)Related Products
