Stable at normal temperature and pressure, avoid humidity and heat, no real melting point at high temperature, slowly decompose above 450℃ and directly turn into gas. At 327℃, the mechanical strength suddenly disappeared.Insoluble in any solvent.
Apart from its ability to react with molten alkali metals, it is not subject to erosion by any material, and does not change even when boiled in hydrofluoric acid, aqua roya, or fuming sulfuric acid, or sodium hydroxide.2. White, odorless, tasteless and non-toxic powder, commonly known as the "king of plastics".
It has excellent chemical stability, corrosion resistance, sealing, high non-viscosity, electrical insulation and good anti-aging endurance.
High temperature resistance, operating temperature up to 250℃.Low temperature resistance, low temperature has good mechanical toughness, even if the temperature drops to -196℃, can maintain 5% elongation.
Corrosion resistance, most of the chemicals and solvents to show the inert, strong acid and alkali, water and a variety of organic solvents.Good weather resistance, best aging life of plastics.
High lubrication, is the solid material friction coefficient of the lowest.
Non-adhesive, is the solid material of the minimum surface tension, not to adhere to any material.
Non-toxic, with physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reactions.
