LSB01 is a polyolefin-based thermoplastic compound containing a specialized flame-retardant system that provides self-extinguishing properties without the release of halogen acids.
It significantly reduces smoke, toxicity, and corrosive gas emissions, making it suitable for use in public buildings, transportation, tunnels, and high-safety cable installations.
Complies with: IEC 60502 Type ST8
Color: Natural

Processing Recommendations
Typical extrusion temperature zones (°C):
Zone 1 – 130–150 | Zone 2 – 130–160 | Zone 3 – 140–160 | Zone 4 – 140–160 | Head – 150–170 | Die – 150–170
Drawdown ratio: 1.2–1.8 L/D ratio ≈ 22
Use low-shear screws and controlled line speeds for best surface quality.
