FAQ

Questions engineers ask first

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

What does '2X' mean in the DIN/LV 112 code FLR2X?
In DIN 72551 and VDA LV 112 material coding, '2Y' represents thermoplastic polyethylene (PE) and '2X' represents cross-linked polyethylene (XLPE / VPE). Combined with 'FLR' (reduced-wall automotive wire), FLR2X is the European metric counterpart to North American SAE J1128 TXL.
Why do engine-bay harnesses prefer FLR2X over heat-resistant PVC FLRYW?
Although both are rated for Class C (+125 °C continuous), FLRYW is still a thermoplastic PVC that softens under extreme short-circuit heating (>180 °C) and contains chlorine. FLR2X is a thermoset cross-linked polyolefin that will not melt even during brief +250 °C fault currents and is completely halogen-free.
Is FLR2X lighter than FLRY or FLRYW of the same cross-section?
Yes. Cross-linked polyethylene has a lower specific gravity (≈1.15–1.22 g/cm³) than PVC compounds (≈1.35–1.42 g/cm³), reducing insulation mass by 12–15 % at identical wall thickness.
Can FLR2X be ultrasonically welded in splice nodes?
Yes. Bare copper Cu-ETP1 conductors in FLR2X-A and FLR2X-B weld cleanly in ultrasonic splice machines, and the thermoset 2X insulation adjacent to the splice resists die heat without flowing back.
