PEBAX heat shrink keeps the 2:1 ratio but caps the wall at 0.25 mm, thinner than FEP or PE — for sections that need a large reduction and a thin wall at once.
The shrink window is narrow — review heat source and dwell time together.
Used for catheter outer jackets that need a large reduction with minimal OD gain. The narrow temperature window makes heat-source control important.
Inner diameter, wall thickness, length and operating environment — those four settle the item. We reply with TDS, MSDS and MOQ.
