Low temperature resistance PTFE tube

Physical and chemical properties:

 Density: 1.3±0.1 g/cm3; Boiling point: 400 ºC; Melting point: 327ºC; Molecular formula: (C2F4)n; Molecular weight: 100.015; Flash point: -119.7±7.1 °C; Exact mass: 99.993614; LogP: 1.90; Appearance: colorless gas; Vapor pressure: 19951.6±0.1 mmHg at 25°C; Refractive index: 1.35; Storage conditions: Store at room temperature in a sealed, dark, ventilated and dry place; Stability: Stable at normal temperature and pressure, avoid moisture, heat, and high temperature. It has no true melting point and slowly decomposes above 450℃, directly becoming gas. At 327℃, the mechanical strength suddenly disappears. It is insoluble in any solvent. It is not corroded by any substance except for reacting with molten alkali metals. Even if boiled in hydrofluoric acid, aqua regia, fuming sulfuric acid, or sodium hydroxide, it does not undergo any changes.

Soluble PTFE Sheet

PTFE is a white, odorless, tasteless, and non-toxic powder, commonly known as "Plastic King". It has excellent chemical stability, corrosion resistance, sealing performance, high lubricity, non-stickiness, electrical insulation, and good aging resistance. It is heat-resistant and can be used at a working temperature of up to 250℃. It is also cold-resistant and has good mechanical toughness at low temperatures. Even at a temperature of -196℃, it can maintain a 5% elongation rate. It is corrosion-resistant and exhibits inertia to most chemical drugs and solvents, and can withstand strong acids, alkalis, water, and various organic solvents. It has good weather resistance and has the best aging life among plastics. It is highly lubricated and has the lowest friction coefficient among solid materials. It is non-adhesive and has the smallest surface tension among solid materials, and does not adhere to any substance. It is non-toxic and has physiological inertness, and can be implanted in the human body for a long time as an artificial blood vessel or organ without any adverse reactions.

While these data can be directly applied to a large extent, it cannot be guaranteed to be suitable for all situations. The properties of the product may differ slightly from the values obtained from raw materials. Different manufacturers may also have slight differences, so it cannot be guaranteed for material selection.
