Fluoropolymer Linings Introduction
Fluoropolymer Lining Material Overview
Fluoropolymer Sheet Linings
Fluoropolymers are a family of plastics that use the fluoride ion to create superior protection against chemical corrosion and permeation. Partially fluorinated polymers provide cost effective corrosion barriers for many lining applications.
Fully fluorinated polymers, due to the strength of the fluorine-carbon bond, provide resistance to attack from virtually all chemicals, making them the lining of choice for severe chemical service. This trait also makes them the linings of choice for transporting and storing ultra-high purity chemicals for the semiconductor industry.
Fluoropolymers as a group are known for –
Fluoropolymers are very effective for lining both steel and dual laminate pipes, equipment, storage tanks, and transport vessels. They’re much more cost-effective than exotic metal alloys or glass-lined containers.

The most chemically inert of all the fluorinated materials. PFA is very similar in composition to PTFE and FEP (fluorinated ethylene-propylene). PFA and FEP both share PTFE’s useful properties of low coefficient of friction and non-reactivity but are more easily formable.
A fully fluorinated thermoplastic which is chemically inert. FEP is subject to attack at ambient temperature by alkali metals, alkali metal organics and fluorine
Is similar to PTFE in that both are chemically resistant to virtually all chemicals except alkali metals and fluorine at elevated temperatures. The primary difference is that PTFE-M is melt flow processable.
is a partially fluorinated thermoplastic. It is resistant to most chemicals except concentrated oxidizing acids at elevated temperatures, alkali amines, certain organic solvents, alkali metals at ambient temperature, fluorine at elevated temperatures, and certain halogenated compounds.
ECTFE is similar to PVDF in its chemical resistance and has somewhat improved resistance to caustic and chloride environments. It exhibits excellent melt processing properties and has the lowest coefficient of expansion of any of the fluorinated materials, making it a good selection for high thermal cycling environments.
The most commonly used fluoropolymer. It has a high level of purity, excellent chemical resistance and a temperature capability of up to about 250 degrees F. It is frequently used for strong acids, solvents and in the handling of DI water. It is not recommended for caustics.
This crystalline polymer has a temperature capability of about 212 degrees F. It is excellent in handling organic acids and alkalis, alcohols, aldehydes and phenols. It is unsuitable for halogens, aromatic and chlorinated hydrocarbons.
This amorphous thermoplastic is the most common. It is low in cost and is easy to fabricate. PVC is excellent in handling many strong acid and alkali solutions and has a temperature capability of about 140 degrees F.
Soft natural rubber has good resistance to most inorganic chemicals, alkalis, and low concentration acids. Hard natural rubber generally has better chemical and heat resistance than soft natural rubber.
Hypalon® is a synthetic based elastomer with excellent resistance to ozone and sunlight, chromic, sulfuric and nitric acids.
Chlorobutyl is a synthetic based elastomer with resistance to ozone and sunlight, strong alkalis and other harsh chemicals.
Neoprene is a synthetic based elastomer and has excellent resistance to alkalis, sulfuric acid, and water. It is not suitable for solvents, halogens or phenols.
Fluoropolymer sheet linings provide excellent corrosion protection and prevent high purity products from contamination and abrasion resistance to the base material by creating a coating of a different material. Electro Chemical produces sheet linings made from fluoropolymers and sheet lining, for example, makes it possible to line or repair on site super large tanks in excess of 100m³.
Sheet Linings are joined, requiring high level welding techniques. Specialized techniques and quality management are very important for this lining and Electro Chemical has the experience and expertise to handle difficult projects effectively. Electro Chemical can provide these services at their location or in the field at your location.
