FEP (Fluorinated ethylene propylene)

FEP fluoropolymer

FEP is highly resistant to chemicals, ageing and climatic influences. The polymer has good dielectric properties and a low dielectric constant. A low coefficient of friction gives the material its non-stick properties. FEP is processed using conventional thermoplastic methods. It is transparent and remains flexible at low temperatures. Like all fluoropolymers, FEP can be sterilised with steam or chemicals. Our CONflon FEP has FDA approval for contact with food.

Its high transparency makes FEP suitable for sight glasses and measuring systems. Combined with its non-stick properties, this makes it suitable for fluid-handling systems in the food industry. Its main applications are in the cable and wire industry (flame protection).

Operating temperature: -200 to +205 °C
Melting temperature: +245 to +280 °C

Frequently asked questions

What is FEP used for?

FEP is a melt-processable fluoropolymer for wire and cable insulation, tubing, linings, films and chemical-process equipment where chemical resistance, electrical insulation and a smooth surface are required.

What operating temperature can FEP support?

As a reference, FEP can be considered for continuous-use temperatures up to about 200 °C. The final limit depends on the grade, design, medium and pressure and must be verified for the application.

Can FEP be extrusion processed?

Yes. FEP is melt processable and is commonly selected for extrusion-based wire coating, tubing and film applications. Processing conditions must be set for the selected grade.

What non-binding reference commercial terms apply to FEP?

Non-binding reference terms: MOQ from 25 kg for standard grades, samples from 1 kg after application review, and a typical 2–4 week lead time for stocked or consolidated batches. Stock is confirmed on request and reserved after order confirmation.

Does Convena provide FEP samples?

Reference samples from 1 kg can be offered after review of the application and delivery country.

Is there a minimum order quantity for FEP?

The reference MOQ for standard grades starts at 25 kg. It is non-binding and confirmed with the offer.

What is the standard packaging for FEP?

A 25 kg bag is the reference packaging for standard grades. Packaging and lot size are confirmed for the offered FEP grade.

Is FEP available from stock or against order?

Stock status is checked for the specific grade and requested quantity and confirmed on request. Available material can be reserved after order confirmation; otherwise it is procured against a confirmed order.

What is the lead time for FEP?

A non-binding reference lead time is 2–4 weeks for stocked or consolidated batches. Actual lead time depends on grade, quantity, stock status, delivery route and documentation requirements and is confirmed with the offer.

Can Convena confirm the specification for a particular batch?

Yes. A TDS gives typical values; confirmation for the offered or supplied batch is based on available batch-specific documentation, such as a COA, and the applicable TDS, SDS and compliance documents.
