PFA Linear Tubing
Wide range of dimensions: diameters, tolerances and lengths.
Conductive versions of PFA Linear Tubing are available on demand.
PFA Linear Tubing are the ideal solution for low pressure applications where it’s required:
- high clarity,
- high temperature resistance,
- high purity grade,
- ease of cleaning,
- good flexibility,
- long durability and chemical resistance.
PFA is a high quality melt-processable fluoroplastics entirely fluorinated with high purity.
PFA excels in all the properties and characteristics offered by both PTFE and FEP.
|Range of working temperatures from -70°C (-95°F) to 260°C (500°F)||High clarity and excellent UV Rays resistance|
|Longer and improved flex-life||Lower gas and vapour permeability|
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|
