Materials | PTFE


The strength of the carbon-fluorine bond and the high atomic weight give PTFE exceptional and unique properties and characteristics.

First of all temperatures resistance: PTFE can work in continuous both in high temperature applications up to 260°C (500°F) and in applications at low temperatures up to -70°C (-94°F), without loss of physical properties.
In addition to the remarkable thermal stability, PTFE has an almost absolute chemical resistance.

PTFE almost total chemical inertia can be attacked only by a few chemicals and only under certain conditions of high temperature and pressure.

Other materials

Other fluoropolymers, with different characteristics and performances, are able to guarantee high performance and quality to our technical solutions.

Fluoropolymers Chemical Resistance

All Fluoropolymers, and especially PTFE, have excellent chemical properties.
The chemical resistance is nearly overall with only few limitations, which can be summarized as follow:

Fluorinated Hydrocarbons Swelling (reversible after short-term exposure, not reversible after long term exposure)
Alkali metals, in solution or molten state Fluorine elimination/Polymer destruction
Halogens, Elementar Fluorine, Chlorine-Trifluoride At very high temperatures possible chemical reaction with polymer destruction (possible explosion)
Monomers: Styrene, Butadiene and Acrylonitrile Possible penetration / Spontaneous polymerization may destroy the polymer
High energy radiation Gamma radiation: physical properties can be reduced by approx. 50% already with 10kGy dosage
Nitrating acid: mixture of concentrations H2SO4 and HNO3 At high temperatures (>100°C) possible decomposition of the fluoropolymer
PTFE also offers the following properties and characteristics, so far have not found in any other plastic material
