Halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms

HS v2022 Code: 390461

About halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms

HS code 390461 covers a critical class of fluoropolymers, including polytetrafluoroethylene (PTFE), which are widely used in a variety of industrial and consumer applications. These halogenated olefin polymers exhibit exceptional thermal and chemical resistance, making them essential materials for industries such as aerospace, automotive, electronics, and chemical processing. Their unique properties and versatility have driven their growing demand and importance within the global economy.

Production process

The primary production method for HS code 390461 materials is polymerization. Monomers, such as tetrafluoroethylene, are subjected to high-pressure, high-temperature conditions to form long-chain fluoropolymer molecules. The resulting polymer is then extruded or molded into various primary forms, including pellets, granules, and powders, ready for further processing and fabrication.

Production inputs

The key inputs for the production of HS code 390461 materials include fluorinated monomers, such as 290330 Fluorinated, brominated or iodinated derivatives of acyclic hydrocarbons, as well as specialized catalysts and processing equipment capable of handling the high temperatures and pressures required. Manufacturers also rely on a range of auxiliary materials, such as lubricants and stabilizers, to ensure the quality and consistency of the final products.

Production outputs

The primary outputs of HS code 390461 are various fluoropolymer resins and compounds, which are then further processed and fabricated into a wide range of end-use products. These materials are often consumed by industries such as 840999 Parts suitable for use solely or principally with the engines of heading 8407 or 8408, 851790 Parts of telephone sets, telephones, etc., and 842199 Parts of machinery and apparatus for filtering or purifying liquids or gases.
