ETFE Granule Extrusion Process HY49003
Ethylene - 4 fluorine ethylene (ETFE) is a new kind of fluorine carbon thermoplastic resin, is ethylene and polyflon under the certain proportion F40 resin, the polymerization generation are mainly applied in anti-corrosion lining. The material has ptfe corrosion-resistant properties of metal, it has unique strong adhesion properties, overcoming the ptfe for metallic not agglutinate disfigurement, together with its average expansion coefficient is close to the expansion coefficient of carbon steel, and the metal ideal ETFE become composite material, has excellent resistance to negative pressure characteristics.
ETFE is a kind of to crystalline polymer, melting point 265 ~ 270 C; Density were 1.73 ~ 1.75 g/cm3; The long-term use of temperature can be in 60 ~ + 170 °C - with good chemical resistance, heat resistance, abrasion resistance, resistance to radiation and impact resistance and some insulation performance, especially mechanical properties is good strength and elongation at break in the PFA and FEP

Main Application of ETFE Granule Extrusion Process HY49003
HY49003 ETFE Resin is suitable for other thermoplastics that lack mechanical toughness, extensive thermal properties, ability to meet unusual thermal, mechanical and chemical environmental limits, or applications that are limited by manufacturing problems. For example, components and linings of the chemical industry, as well as mould parts using metal inserts with thick sections at high temperatures. HY49003 ETFE Resin is suitable for many end products, including chemical services such as lining valves and fittings, pump shells and impellers, Stuffing and other wear-resistant linings; high-temperature electrical components and insulation; fasteners, bellows and piping work; and film.
ETFE is characterized by low density, radiation resistance, easy processing, good toughness, chemical corrosion resistance, weathering resistance, and good optical and electrical properties. The thermal stability of ETFE copolymers increases with the increase of TFE content. The difference between the melting temperature and the decomposition temperature will be very large, and the copolymers can be processed by a general method. The melting point of bulk polymerized ETFE is closely related to the composition of polymerization. Two maximums appear on the melting curve. When TFE is less than 48, the temperature of the two extreme values is quite different, and the low temperature point and the low molecular weight part are different. When the content of TFE is between 48% and 50%, the values of the two poles are very close, showing a double distribution peak. The melting curve of ETFE in suspension polymerization shows only a single peak, which indicates that the structure and chemical homogeneity are good. Different from the random structure of FEP and PFA, ETFE has alternating structure. Compared with PTFE and FEP, it has excellent electrical properties, chemical resistance and aging resistance, except for lower heat-resistant temperature. At the same time, the introduction of ethylene greatly improved the radiation resistance of copolymers and the improvement of mechanical properties, such as toughness, hardness, cold flow and creep resistance of the copolymers were better than those of PTFE and FEP. The dimensional stability of the copolymers was comparable to that of nylon or polyformaldehyde. In order to improve the high temperature mechanical properties of ETFE, the commercial ETFE resins generally contain a small amount of third monomer. ETFE resin can be synthesized by bulk polymerization, water phase polymerization, non-aqueous dispersion polymerization and mixed phase dispersion polymerization.
