Optically Clear Peelable Heat Shrink Tubing

Conventional peelable heat shrink tubing has one limitation that catheter assembly engineers have worked around for decades: you cannot see through it during the reflow process. Junkosha's optically clear FEP-based peelable heat shrink solves this directly — the transparent tubing gives assembly operators a direct view of the catheter construction underneath during heat application, enabling real-time process verification without disassembly.\n\nThe optical clarity eliminates the need to pause and peel a test sample mid-process to confirm braid coverage, adhesive flow, or layer alignment. For high-value catheter assemblies where scrap cost per unit is significant, this visibility reduces rework and improves first-pass yield.\n\nThe peel-away mechanism is identical to Junkosha's established opaque ITP-01 line — the tubing shrinks to conform during reflow and then peels cleanly without residue, without manual skiving, and without contaminating the catheter lumen. The transition to the clear FEP compound required no changes to existing reflow profiles or tooling.\n\nJunkosha has tripled production capacity for this product to meet anticipated demand from catheter manufacturers transitioning existing processes. Standard shrink ratios and wall thicknesses match the existing opaque product line for straightforward specification substitution.\n\nAvailable in Israel through Koto Electronics.
