Double-Layer Graphite PTFE Yarn
Double-layer graphite PTFE yarn with colloidal graphite and auxiliary additives added between two film layers. High graphite content, high tensile strength and uniform diameter — ideal base material for packing braiding. Available with different oil and graphite contents on request.
Inquire about Double-Layer Graphite PTFE YarnMade from PTFE raw material through mixing, stretching, degreasing and heat-setting processes, with colloidal graphite and lubricating oil added to form a film; colloidal graphite and other auxiliary additives are then added between two film layers. Our double-layer black PTFE yarn uses proprietary technology and features high graphite content, high tensile strength, uniform yarn diameter and neat yarn folding. It can be widely used as the base material for braiding various packings.
Depending on customer requirements, we can provide double-layer black PTFE yarn with different oil content and graphite content.
