Polytetrafluoroethylene
Chemflour ® PTFE Tubing is used as a pressure tubing in general chemical applications, such as delivery of natural gas and paint delivery lines.

Saint-Gobain Performance Plastics' careful selection of resin type, particle size, temperature and pressure produces smooth, non-porous, dimensionally stable tubing. Made out of polytetrafluoroethylene resin, Chemfluor® PTFE Tubing has the highest working temperature of any fluoropolymer tubing available today. It is widely used as a pressure tubing in general chemical applications such as delivery of natural gas and mineral oils, toxic gas monitoring and paint, varnish or adhesive delivery lines. Chemfluor® PTFE Tubing also services numerous applications in the automotive, electrical and appliance markets.

Used in Dozens of Applications
If your application is highly demanding, there’s a Chemfluor® tubing for you. Chemfluor® tubings have outstanding chemical and physical characteristics because they are made using fluoropolymers and these materials are processed under stringently controlled conditions. In addition to being chemically inert, Chemfluor® tubings can be used in a broad range of temperatures, from -400°F to 500°F.

Meets FDA Criteria
Because no plasticizers, stabilizers or fillers are used, Chemfluor® tubings are pure and non-contaminating. They are non-toxic and manufactured using resins that meet FDA criteria. The natural flexibility and performance-proven, anti-stick inner surface of Chemfluor® tubing make handling sticky and viscous fluids much easier, and facilitate speedy clean-up. The low surface energy minimizes adsorption of proteins, essential oils and metals. Unlike metal and rubber alternatives, Chemfluor® tubings are noncorroding and non-oxidizing. Unlike other plastic materials, they are unaffected by solvents, acids and fuels.
