Fluorinated ethylene propylene FEP Resins

CAS No: 25067-11-2

FEP (Fluorinated Ethylene Propylene) resins are a specialized category of FEP materials tailored for extrusion processes and Molding Processes. These resins offer a unique set of properties and advantages ideal for a wide range of applications. 

Features and Benefits of Peflon™ FEP Resins

Fluorinated ethylene propylene FEP resins have a higher melt flow rate (MFR). This characteristic allows for excellent flowability during the process, making them well-suited for creating various shapes, wires, tubes, film, profiles, and coatings.

FEP materials, exhibit exceptional non-stick properties, making them ideal for applications where preventing adhesion is crucial.

FEP resins, including extrusion grades and molding grades, are renowned for their resistance to a wide range of chemicals and solvents. This attribute ensures product integrity in challenging environments.

 Extrusion-grade FEP resins can withstand a broad temperature range, from extremely low temperatures to high heat, without compromising their mechanical and electrical properties.

Gaskets and Seals

Compression-molded FEP is used to produce seals and gaskets in automotive, aerospace, and industrial equipment, providing excellent sealing performance

FEP Resin Processing

Fluorinated Ethylene Propylene (FEP) resin, renowned for its versatile properties, can be processed through various methods to create an array of products and coatings. Here are the primary processing techniques used for FEP resin:

Compression Molding, Injection Molding, Hot Forming, Coating, Calendering, Melt Extrusion etc.

Compression Molding

Heated FEP is placed into a mold and compressed to shape it.

Suitable for complex shapes or larger-sized FEP products

Injection Molding

Molten FEP is injected into molds, cooled, and solidified to produce various parts.

Ideal for items like valves, connectors, and components.

Hot Forming

FEP sheets or stock material are heated and manually or mechanically formed into desired shapes.

Used for small batch production or unique shapes.

fep coating

Coating

FEP is coated onto other materials like metal or fiberglass for its non-stick and lubricating properties

Typical in cookware, coating for pipes, and various non-stick applications

Calendering

Molten FEP resin is passed through roller equipment to form thin films or sheets.

Commonly used to produce FEP films, sheets, and expanded sheets

fep cable extrusion

Melt Extrusion

FEP pellets are heated to a molten state and then extruded into continuous shapes, such as rods or tubes

Widely used for manufacturing wire and cable insulation, pipes, films, and rods.
