PCTFE Plates * Newsletter 2015-04

Unbreakable PCTFE plates for use in environment, laboratories and pilot plants

PCTFE, the technical abbreviation for polychlorotrifluoroethylene, is a hard, in a wide range exceptionally temperature-resistant plastic. It belongs to the thermoplastics. PCTFE can be permanently used between -255  C (temperature of liquefied hydrogen) and +150  C, for short periods even up to +200  C. The uncolored, opaque material, the hardness of which is not reached by any other fluoroplastic, is amorphous.

PCTFE features extremely low gas permeability and is flame-resistant even in pure oxygen. Moreover, PCTFE is very dimensionally stable compared with the chemically related PTFE and tends hardly noteworthy to flow even under strong pressure load. Similar to PTFE, it can however be machined by cutting processes such as turning, milling and planing without any problems. PCTFE is also adhesible by means of special adhesives.

PCTFE is highly resistant to environmental influences as well as UV radiation and X-radiation and thus superior to many other plastics. Also the chemical stability of PCTFE surpasses that of most other plastics. PCTFE is not affected by either acids, not even by fuming nitric acid and hydrofluoric acid, or alkalies such as concentrated sodium hydroxide or caustic potash. PCTFE is resistant even to solvents, halogenated as well. Only free alkali metals are able to destroy the plastic.

RCT Reichelt Chemietechnik has a select range of high-quality PCTFE Plates in stock. These high-quality semi-finished products have a shore hardness A between 75° and 80° and a density of approx. 2.2 g/cm3. Due to their remarkable mechanical and technical as well as chemical properties PCTFE plates of RCT Reichelt Chemietechnik are preferably used as construction materials for the nuclear technology and cryogenic engineering and in the medical engineering, moreover in the chemical pilot plant and apparatus engineering, for superstructures in outdoor areas, and also in the field of electronics and electrical equipment particularly due to their outstanding high resistivity.

PCTFE plates of RCT Reichelt Chemietechnik are available in graded, practice-oriented material thicknesses between 1 mm and 10 mm in four standard dimensions of 150 mm x 150 mm, 200 mm x 100 mm, 200 mm x 200 mm as well as 350 mm x 150 mm each.

The whole range of PCTFE plates is represented in detail in our handbook THOMAPLAST® II (Semi-finished products).
