stability
1. Stable under normal temperature and pressure, avoid humidity, heat and high temperature

No real melting point, above 450℃ slowly decompose, directly into gas. At 327℃, the mechanical strength suddenly disappeared. Insoluble in any solvent. In addition to the reaction with molten alkali metal, not by any substance erosion, even in hydrofluoric acid, aqua aureus or fuming sulfuric acid, sodium hydroxide boiling, also does not have any change.

2. White, odorless, tasteless, non-toxic powder, commonly known as "plastic king". It has excellent chemical stability, corrosion resistance, sealing, high lubrication, non-viscosity, electrical insulation and good aging resistance. High temperature resistance, working temperature up to 250℃. Low temperature resistance, good mechanical toughness at low temperature, even if the temperature drops to -196℃, it can maintain 5% elongation. Corrosion resistance, inert to most chemicals and solvents, strong acid and alkali, water and all kinds of organic solvents. Good weather resistance, has the best aging life of plastics. High lubrication, is the lowest friction coefficient of solid materials. Non-adhesion, is the smallest surface tension in solid materials, does not adhere to any substance. Non-toxic, has physiological inertia, as artificial blood vessel and organ long-term implantation in the body without adverse reaction.
