Modified PTFE, the next generation molding powders, is a chemically modified granular PTFE resin with enhanced properties for applications beyond those of conventional PTFE. Modified PTFE has a lower molecular weight than that of conventional PTFE allowing for a lower melt viscosity. However with the modifier used, the mechanical properties of the material, are that of conventional PTFE resulting in a dramatically reduced creep (cold flow) resistance. The lower melt viscosity allows better particle fusion during sintering cycles, resulting in a product with lower permeability from a denser polymer structure.
Additional Benefits:
• A substantially lower deformation under load resistance.
• Lower permeation due to dense polymer structure and fewer voids slowing the transmigration of aggressive liquids and gasses.
• Bond parts by clamping them and re-sintering them in an oven. Moderate clamping pressure and a bond strength which approaches that of the material itself.
• Smoother surface finish with lower porosity.
• Improved stress recovery at elevated pressure than that of conventional PTFE.
• Extreme resistance to aging and/or embrittlement.
