MCP Engineering Plastics Limited are PCTFE Rod suppliers and PCTFE Rod manufacturers.
We extrude PCTFE rods from 5mm diameters to 45mm diameters. On request we also offer grinded material and extra annealing for strict tolerances. Depending on the size you require, we offer PCTFE rod in one, two or three meter lengths.
PCTFE, Polychlorotrifluoroethylene is a melt-processable chlorofluoropolymer. The presence of a chlorine atom, which has a greater atomic radius than that of fluorine, gives rise to irregularities in the polymer chain and reduces polymer crystallinity. This results in PCTFE having a relatively low melting point among fluoropolymers. It is also the polymer with the lowest water vapor and moisture absorption rate. It resists ignition because its Limiting Oxygen Index (LOI), which is greater than 95.
PCTFE rod resists attack by most chemicals, a property that is exhibited due to the presence of its high fluorine content. It is oxidation resistant because it does not have any hydrogen atoms.
The main field of application of PCTFE is cryogenics due to the fact that it is the fluoropolymer that best retains its mechanical properties at extremely low temperatures and is therefore the least fragile of the fluoropolymers.
PCTFE is incompatible with alkaline metals and in some cases with organic amines. Its use is not recommended at temperatures above 150°C.
PCTFE rod is recommended for cryogenic application and handling of gases. PCTFE rod has better mechanical properties than other fluoropolymers and low permeability.
MCP Engineering Plastics Limited, based on the Hertfordshire and Essex county border, are an established and experienced PCTFE Rod supplier and manufacturer to a range of industries throughout the UK. We have a wide range of filled materials, in all sizes, ready for despatch, ex-stock.
