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 -
PEEK vs Polymer PTFE/FEP Maching
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 – PFA Properties and FEP Properties
Chemical properties of FEP are similar to those of PTFE and PFA. PFA Properties PFA polymers are fully fluorinated and melt-processible. They have chemical resistance and thermal stability comparable to PTFE. Specific gravity of perfluoroalkoxy resins is in the range of 2.12e2.17. PFA has an uppe...Read more -
Nylatron vs Polymer PTFE/FEP Machining
Nylatron is a tradename for a family of nylon plastics, typically filled with molybdenum disulfide lubricant powder. It is used to cast plastic parts for machines, because of its mechanical properties and wear-resistance. PTFE (polytetrefluoroethylene) is a soft, low friction fluoropolymer with o...Read more
