Polyimide (TPI,KAPTION) is a group of high performing polymers known for their exceptional chemical, thermal, and mechanical performance properties. These materials demonstrate exceptional thermal stability in high and low temperatures and are extremely flame resistant.
  TPI KAPTION composite is a high lubricity polyimide blend for applications that require lower surface friction yet do not require the performance of pure TPI KAPTION maintains broad chemical resistance and good dielectric properties in addition to its reduced coefficient of friction. PI, KAPTION  is available in tubing and as a coating for over-the-wire ( insulated wire cable) applications.
For insulated wire,TPI  KAPTIONprovides a low-friction wire for easier deployment or insertion into tubing. With TPI KAPTION  wire, inside diameters offer low resistance to inserted devices or tools (pushability) while the outside remains bondable without etching.
TPI KAPTION can also be produced in a layered composite construction with our conventional polyimide or with PI KAPTION
Composite layering polyimide and TPI KAPTION allows users to further tailor polyimide tubing or coating properties.
