What is material FEP?

Table of Contents

FEP (fluorinated ethylene propylene) is a tough, flexible copolymer of tetrafluoroethylene and hexafluoropropylene. It is often used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required. FEP has outstanding electrical properties and UV resistance.

What is FEP dielectric?

Fluorinated ethylene propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques.

What is FEP insulation?

FEP stands for Fluorinated ethylene propylene. It is a type of fluoroplastic that is used as a cable outer to insulate and protect temperature sensor wire. It has very similar properties to PTFE and PFA such as low friction and non-reactivity to chemicals.

Is FEP hydrophobic?

Although FEP is hydrophobic and exhibits a relative low coefficient of friction it can not match the performance of other high performance, low friction coatings reported in the literature [8,13].

Is FEP hygroscopic?

Hygroscopic Expansion Because the moisture absorption of DuPont FEP fluorocarbon film is less than 0.01% when totally immersed in water, changes in relative humidity have little effect on the film.

Is FEP conductive?

Electrical FEP exhibits most of the properties of PTFE. However, because of its excellent electrical FEP properties, FEP tubing is a valuable and versatile electrical insulator.

What color is FEP?

clear transparent
Polyfluor is not only the PTFE specialist, but is also the market leader in FEP. PTFE and FEP are quite similar to each other. While PTFE is milky white in color, FEP is clear transparent.

What thickness is FEP film?

Our FEP sheets come in 0.05mm, 0.1mm, 0.15mm and 0.2mm thickness and come in a A4 size sheets (8″ x 11″, 280mm x 200mm). Each order includes 4 sheets packaged in a plastic resealable bag.

What is FEP film used for?

The FEP film is the double-layered and transparent foil installed in the rack attached to the resin tank. It creates a clean way for the UV light to cure liquid resin during the whole printing process.

How long does FEP film last?

FEP films should be replaced when they have major signs of wear and tear such as deep scratches, punctures, and regularly result in failed prints. Some can get at least 20-30 prints, though with proper care, FEP sheets can last several prints without damage.

How long does a FEP last?

Can you cut FEP film?

Use scissors to cut your new sheet of FEP film about 2 inches (5.1 cm) wider and taller than the metal frame it’s going to sit in. Your measurements don’t have to be exact, but you need to leave some excess on the outside so you can cut it down later.

How do you stop resin from sticking to FEP?

To stop your resin 3D prints sticking to the FEP, you should make sure you have enough bottom layers and bottom layer curing time, so it has enough time to harden. Use PTFE spray on your FEP film, let it dry, and this should create a lubricant to stop the resin from sticking to the resin tank.

Can the FEP be too tight?

In addition, the build platform needs to be precisely leveled and the contact with the FEP film should not be too loose or too tight as it may lead to sticking or other printing problems.

What Happens When FEP is too tight?

But if the Fep is worn or too loose or too tight, it may affect the peel force, resulting in the sticking problem. The editing of the part itself, such as improper placement of the angle, hollowing, punching, etc. may result in excessive peel force/separation force, which may also lead to sticking.

What are the properties of electrical FEP tubing?

Electrical FEP exhibits most of the properties of PTFE. However, because of its excellent electrical FEP properties, FEP tubing is a valuable and versatile electrical insulator. Weathering FEP tubing products are virtually unaffected by weather elements.

What is FEP plastic made of?

How does FEP compare to other thermoplastics?

It has a fairly high density among thermoplastics. In addition, it has a fairly high ductility and a very low tensile strength. The graph bars on the material properties cards below compare FEP to: fluoroplastics (top), all thermoplastics (middle), and the entire database (bottom).
