Heat shrinkable tubing in KYNAR material

PVDF has very good resistance to hydrocarbons, fuels, oils, solvents and many chemical agents. This characteristic is decisive in the aeronautical, rail or petrochemical sectors, where electrical beams can be exposed to technical fluids at all times.

On a hydraulic test bench, cables are regularly exposed to hot oil projections and cleaning solvents. One tubing Kynar® long-lastingly protects welds and splicing without degrade in contact with fluids. Where a standard polymer could inflate or crack, PVDF retains its integrity. The beam remains reliable despite a chemically demanding environment.

More rigid on the surface than a polyolethin classic, tubing Kynar® offers increased resistance to abrasion and cutting. After tightening, it forms a durable protective envelope that secures conductors subjected to vibration, friction against metal parts or repeated stresses.

In railway equipment subject to permanent vibration, a beam passes through a metal structure. One tubing Kynar® is used on potential friction zones. Its more resistant surface limits wear by abrasion and protects the driver against accidental cuts. This robustness contributes to the longevity of the installation in a dynamic environment.

Kynar® sheaths generally conform to industrial standards such as UL 224, MIL-I-23053 or equivalent, with suitable fire classifications (e.g. VW-1). They thus meet the requirements of the regulated industries where long-term safety and reliability are a priority.

For equipment intended for aeronautical export, the specification imposes specific UL and MIL standards. Use of a heat shrinkable tubing in Kynar® conforming to these standards simplifies the technical validation of the finished product. The manufacturer thus secures its approval without having to justify an alternative solution. This represents a significant saving of time in quality audits.
