Application fit

Is FLR9Y-A right for your machine?

Specified for weight-critical EV and passenger-car cockpit harnesses, roof and door modules, high-density ECU signal looms and halogen-free cabin wiring requiring Class C (+125 °C) rating without cross-linking.

Fixed installation

Suitable

Reduces insulation mass by ~25–30 % vs PVC while meeting Class C (+125 °C) and high scrape standards.

Switchgear & control cabinet wiring

Suitable

Hard, low-friction PP wall inserts cleanly through micro-connector mat seals without buckling.

Free-hanging vertical run

With conditions

PP has higher flexural modulus than PVC; for cold flexing door boots prefer FLRYK or FLR2X-B.

FLRYK cold-flex wire

Motor stator, traction & converter leads

Not suitable

Thermoplastic PP softens above +160 °C; for high short-circuit overload use thermoset FLR2X.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does '9Y' stand for in DIN 72551 and VDA LV 112?
'9Y' is the DIN VDE 0207 / DIN 72551 material code for polypropylene (PP) thermoplastic insulation.
What are the main advantages of FLR9Y-A over PVC FLRY and cross-linked FLR2X?
Compared with PVC (FLRY/FLRYW), FLR9Y-A is 100 % halogen-free, contains zero volatile plasticisers (eliminating cockpit windshield fogging), has 25–30 % lower insulation density and offers much higher needle-scrape resistance. Compared with FLR2X (XLPE), FLR9Y-A requires no electron-beam or silane cross-linking step and is a fully recyclable thermoplastic.
Why is FLR9Y-A favoured for ultra-thin 0.13–0.35 mm² micro-connector wires?
Polypropylene has high column stiffness and a hard, slick surface that allows fine 0.13–0.35 mm² wires to be pushed through tight silicone mat seals without kinking, while resisting terminal-lance cut-through.
Where should FLR2X still be chosen over FLR9Y-A?
In high-current engine-bay power circuits where a short-circuit fault could briefly heat the conductor above +165 °C (the crystalline melting point of polypropylene), thermoset cross-linked FLR2X prevents insulation melt-through.
