FeP

FEP is an acronym that can refer to several concepts in different fields. In materials science, Fluorinated ethylene propylene (FEP) is a fluoropolymer in the PTFE family. It is a copolymer of tetrafluoroethylene and hexafluoropropylene. FEP combines chemical resistance, electrical insulation, and optical clarity with thermoplastic processability. It can be melted and processed by conventional methods such as extrusion and molding, unlike PTFE resins that require special processing. This makes FEP suitable for tubing, linings, films, and wire insulation, including some food-contact applications where permitted. It maintains performance across a wide temperature range and exhibits low permeability and high dielectric strength.

In computing and information technology, Front-end Processor (FEP) refers to a dedicated processor or subsystem that handles network communications and I/O tasks on behalf of a host computer. An FEP offloads protocol processing, error detection, buffering, and data routing from the main CPU, enabling higher throughput and scalability in environments with heavy network traffic. Front-end processors have historically been used with mainframes and enterprise servers, and may include protocol gateways, line adapters, and transaction processing components.

Because FEP is an acronym with multiple meanings, the intended sense is determined by context and field of use.
