Copied
  • This tough, very thin walled, and semi-rigid tubing has excellent electrical properties while offering good resistance to chemicals.
  • TK20 is highly flame retardant and UL 224 VW-1 approved.
Application Typical applications of this translucent tubing are where high-temperature performance is required. Also very suitable for applications that ask for visual inspection of covered components, or if low friction surface is needed. TK20 is also used as oil stop for energy cables.
This thin walled, translucent heat shrink tubing is often used for chemical applications.
