PCTFE vs PTFE PCTFE and PTFE are two fluoropolymers with similar chemical formulas. PCTFE is a derivative of PTFE composed of an additional chlorine atom. This atom is responsible for the low melt index of PCTFE. The coefficient of thermal expansion of PCTFE is also low compared to that of...
FEP, a perfect material for the use of UVC lamps Disinfection of water, work surfaces, air or objects can be critical in some circumstances and there are many limitations to the use of chemical disinfectants. UVC lamps can overcome these disadvantages. However, the use of this equipment may require some...
PCTFE O-ring Specialized in the manufacture of seals, SPN produces PCTFE O-rings. SPN has been active in the transformation and machining of high performance plastics for 80 years. To manufacture a PCTFE O-ring, SPN uses PCTFE or polychlorotrifluoroethylene compatible with oxygen gas. In addition to seals, SPN also produces other types...
PCTFE film For more than 80 years SPN or Société des Plastiques Nobles has been working in the transformation and machining of high-performance plastics intended to be subjected to extreme conditions of heat and cold.

PCTFE datasheet Enclosed is the PCTFE datasheet PCTFE or polychlorotrifluoroethylene is one of the noble plastics most used in the sectors using in special and corrosive gases. Valve and valve manufacturers also often use this polymer for the manufacture of seals. This is mainly due to the advantageous technical properties of...
Information on PCTFE rods at SPN As a specialist in engineering plastics, SPN can supply the manufacturers with bars and rods in various materials including PCTFE (or PTFCE in French). In order to produce polychlorotrifluoroethylene rods in long dimensions, SPN uses the extrusion technique. This process allows SPN to offer...
PCTFE Chemical compatibility PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE) marketed as Kel-F, Voltalef or Aclar. It differs from PTFE by the addition of a chlorine atom to its chemical structure, which gives it a relatively low melting point compared to other fluoropolymers. This plastic is particularly popular for its...
