Application of product
APPLICATION
The application of fluoropolymer products is developing fast in recent years.
PTFE is well-known as " king of plastic".As an alternative of traditional plastic, PTFE and other modified PTFE products are now widely used for their many advantages:
Non-stick;
Corrosion resistance;
Ozone and sunshine tolerance;
Thermal stability;
Fire resistance;
Physiological inertia;
Electric insulation.
Here shows some main fields that PTFE products are widely used.
Chemical industry
Aerospace industry
Medical instruments
Electronic engineering
Semi-conduct industry
Mechanical industry

FAQ
FAQs about FEP
What is FEP?
FEP refers to fluorinated ethylene propylene, which is a material that is extremely resistant to chemicals, broad temperature exposure and cracking. Often used in the manufacture of tubing and pipes, FEP offers high thermal stability, low permeability, excellent UV transmission and superior insulation properties. For this reason, the material can be used in a number of applications, including chemical processes, laboratory applications, UV water purification systems, food processing, electrical insulation, telecommunications and more. FEP tubing and pipes offer excellent clarity and are often used in sight glass and other flow monitoring applications.
Can FEP tubing be softened by heating?
Yes, FEP tubing can be softened through heating by means of certain processes. The melting temperature of FEP tubing is much lower than PTFE. For this reason, FEP is often used in dual containment tubing. This type of tubing is generally made up of an outer PTFE tube and an inner FEP tube. As heat is applied, the FEP softens and flows over the component, while the PTFE tube shrinks down onto the FEP. Once cooled, the FEP sets and is bonded to the PTFE, forming a moisture-tight capsule. The final product is then formed and can generally withstand working temperatures of up to around 410 °F.
What is DKT FEP tubing?
FEP (fluorinated ethylene propylene) tubing is an ideal choice for tubing applications that require chemical resistance as well as broad temperature exposure. DKT FEP tubing has excellent clarity and a very good UV transmission rate, making it an excellent choice for sight glass and other flow monitoring applications, as well as UV water purification systems and coil hose constructions.
What are the features of DKT FEP tubing?
DKT FEP tubing has a number of valuable features. It is made of 100% virgin grade high performance resins, which are
resistance to stress cracking. The tubing is chemically inert to most industrial chemicals and solvents, has a high thermal
stability, low permeability, and excellent UV transmission. The moisture absorption is nearly zero, Other features include superior electrical insulation properties, as well as non-flammable and self extinguishing properties.
What can DKT FEP tubing be used for?
DKT FEP tubing can be used in chemical processes, laboratory applications, UV water purification systems, ground water
monitoring, ground remediation, food processing and electrical insulation. The tubing can also be used in telecommunications and automotive paint spray.
