PTFE Seals Polytetrafluoroethylene (PTFE) Seals TEFLON? Seals PTFE Shaft Seals PTFE Oil Seal Stainless Steel PTFE Metal Oil Seal
When rubber seals falls short of meeting the sealing requirements, Polytetrafluoroethylene (PTFE seals) steps in as the ultimate alternative. PTFE is a material that can be molecularly modified to enhance characteristics such as deformation, dielectricity, transparency, weldability, and hot formability. Furthermore, it can be loaded to improve deformation characteristics, limit wear, expansion, and conductivity.
The strength of PTFE lies in its ability to minimize friction; it is a self-lubricating polymer, dielectric, resistant to solvents and aging, capable of withstanding extreme temperatures ranging from -200°C to +260°C.
Thanks to these features, we can produce seals resistant to high temperatures, acids, and solvents.Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, consisting of Fluorine and Carbon atoms, making it one of the most versatile plastics for applications not accessible to other materials. PTFE is produced from tetrafluoroethylene monomer (TFE) using two different polymerization techniques: granular PTFE from suspension polymerization, and fine powders coagulated or dispersions from dispersion polymerization.
PTFE Seals Distinctive characteristics:
Chemical Properties of PTFE seals
1. Chemical Inertia:
PTFE is inert to the vast majority of known chemical reagents, ensuring exceptional corrosion resistance.2. Insolubility:
