Tubing - Fluoropolymer - ChemfluorŽ PFA Tubing & Rod

PFA, which can operate in temperatures ranging from -320°F to 500°F, is chemically inert and virtually non-porous.

 

PFA, which can operate in temperatures ranging from -320°F to
500°F, is chemically inert and virtually non-porous. Used in any application with high heat and chemical requirements, ChemfluorŽ PFA's non-stick characteristics promote ease of movement of viscous, aggressive compounds, and prevent binding of proteins.

Used in Dozens of Applications
If your application is highly demanding, there’s a ChemfluorŽ tubing for you. ChemfluorŽ 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, ChemfluorŽ tubings can be used in a broad range of temperatures, from -400°F to 500°F.

Meets USP Class VI Criteria
ChemfluorŽ PFA tubing fully complies with the requirements of USP Class VI Criteria and is non-toxic, non-hemolytic and non-pyrogenic. The three test types that are performed on ChemfluorŽ PFA tubing are systemic toxicity, intracutaneous toxicity and muscle implant.

Meets FDA Criteria
Because no plasticizers, stabilizers or fillers are used, ChemfluorŽ 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 ChemfluorŽ 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, ChemfluorŽ tubings are noncorroding and non-oxidizing. Unlike other plastic materials, they are unaffected by solvents, acids and fuels.
