Injection PTFE

PTFE Injection

Most plastic components are produced by injection molding. This production process allows the component manufacturer to produce complex geometries at low unit cost. Polymer injection molding is the most widely used production process for plastic components. Unfortunately, PTFE cannot be injected because it has a high viscosity when in a...

PTFE and PCTFE can be used as solid lubricant in cryogenics

Thanks to the particularly exceptional properties of polymers, they are often used as solid lubricants in the field of tribology, especially in cryogenic environments. At atmospheric pressure, cryogenic fluids have very low viscosities. For liquid oxygen, the viscosity is 0.20-10-3Pa-s and for liquid nitrogen it is 0.16-10-3Pa-s [25]. This makes...

Wear resistance of metals and PCTFE at cryogenic temperature

In cryogenic environments, PTFE (polytetrafluoroethylene) and PCTFE (polychlorotrifluoroethylene) are the most commonly used fluoropolymers. Fluoropolymers are polymers where the atoms have been modified. Concretely, by substitution, fluorine atoms have taken the place of hydrogen atoms. This process of atom substitution has improved the chemical resistance and thermal resistance of...
