PTFE 60 X
PTFE 60 X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion.
PTFE 60 X offers the excellent combination of properties typical of Teflon fluoroplastic resins.
PTFE 60 X
is widely used for conformable, high performance sealing materials and as tape for wire and cable insulation.
PTFE 60 X is extruded using a liquid processing aid such as naphtha. In the paste extrusion process, the powder is mixed with a lubricant aid and then compressed into a cylindrical preform slug under light pressure (1.5-2.0 MPa [220-290 psi]). The preform slug is placed in the cylinder of a paste extruder, where the composition is forced under high pressure through a finishing die to produce beading, tubing, or wire coatings. After extrusion, the product is a low-density, but coherent, fibrous structure. After removal of the lubricant by heating within the range of 100-300 °C (212-572 °F), the extrudate can be either sintered above its melting point of around 345 °C (653 °F) to produce a void-free PTFE article or calendered and stretched to produce unsintered or semisintered articles.
