            Polyetheretherketone PEEK film of high-performance plastic film

            2021-05-28

            Polyetheretherketone PEEK film of high-performance plastic film
            PEEK (polyether ether ketone) plastic raw material is an aromatic crystalline thermoplastic polymer material with a melting point of 334°C. It has high mechanical strength, high temperature resistance, impact resistance, flame retardancy, acid resistance, hydrolysis resistance, abrasion resistance, and fatigue resistance. , Radiation resistance and good electrical properties.
            High temperature resistance
            PEEK resin has a relatively high melting point (334°C) and glass transition temperature (143°C). The continuous use temperature is 260°C, and its 30% GF or CF reinforced grades have a load thermal deformation temperature as high as 316°C.
            Mechanical properties
            PEEK (polyether ether ketone) plastic raw material resin has good toughness and rigidity, and it has excellent fatigue resistance to alternating stress comparable to alloy materials.
            Flame retardant
            The flammability of the material is the ability to maintain combustion after being ignited with high energy obtained from the mixture of oxygen and nitrogen. The recognized standard for measuring flammability is UL94. The method is to first ignite a vertical sample of a predetermined shape, and then measure the time it takes for the material to automatically extinguish. The PEEK test result is V-0, which is the best grade of flame retardancy.
            Smoky
            The standard for measuring the smoke and dust produced by the burning of plastic is ASTM E662. This standard uses the National Bureau of Standards (NBS) smoke and dust laboratory to measure the visible light dimming degree of the smoke and dust produced by the combustion of standard shape samples in units of specific optical density. The test can be carried out under conditions of continuous combustion (flame) or interruption of combustion (no flame). Among plastics, PEEK has the lowest smoky properties.
            Toxic gas escape
            PEEK is the same as many organic materials. During pyrolysis, PEEK mainly produces carbon dioxide and carbon monoxide. Using the British aircraft test standard BSS 7239 can detect very low concentrations of toxic gas escape. This detection process requires a space of 1 cubic meter. Completely burn 100 grams of the sample, and then analyze the toxic gas produced in it. The toxicity index is defined as the ratio of the concentration of toxic gas produced under normal conditions to the dose that can be lethal in 30 minutes. The index of PEEK450G is 0.22, and no acid is detected. gas.
