Polymer PTFE – Fine Powder Lubricated Extrusion Resin
PTFE is a very useful material because it has a unique combination of properties. PTFE is chemically inert, weatherable, excellent electrical insulation, high temperature resistance, a low coefficient of friction and non-adhesive properties. Shrinkable tubing is also used as roll covers and to pr...Read more -
Fluorinated ethylene propylene VS PTFE
Fluorinated ethylene propylene or FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the PTFE (polytetrafluoroethylene) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. Fluorinated ethylene propylene was inv...Read more -
Polymer Properties of PTFE – PTFE Properties
PTFE has excellent properties such as chemical inertness,heat resistance (both high and low), electrical insulation properties, low coefficient of friction (static 0.08 and dynamic 0.01), and nonstick property over a wide temperature range (260 to þ260 C). It has a density in the range of 2.1e2.3...Read more -
PFA and TFM PTFE Excellent Material Choice for Bellows and Diaphragms
PTFE (polytetrafluoroethylene), aka polymer, is typically the first choice polymer for bellows and diaphragms, but did you know that PTFE isn’t the only polymer you can choose from? In this article we are going to compare two other polymers – PFA and TFM – to PTFE as a material choice ...Read more -
PEEK vs UHMW Machining
PEEK is a temperature-resistant engineered thermoplastic that performs well under exposure to high temperatures and chemical environments. This material’s ability to retain its physical properties and withstand temperatures up to 480 degrees F makes it a highly valuable material that is sui...Read more -
Polymer Properties – PCTFE & ETFE & ECTFE Properties
PCTFE is a semicrystalline polymer with a helical polymer chain and a pseudohexagonal crystal. PVDF and equimolar ETFE are isomers but the latter has a higher melting point and a lower dielectric loss than the former.Similar to ETFE, ECTFE terpolymers (same termonomers) have better mechanical and...Read more
