Customers rely on BASF because
Ultradur® PBT simply outperforms
any other product out there.
More Space = More Fibers
With FOC buffer tubes it’s all about thin walls and high speeds. Ultradur® B 6550 LN and B 6550 LNX are solutions that enables high speed extrusion at smaller diameters.
Ultradur® B 6550 LN and LNX are specially formulated with a lubricant and nucleating agents to combine easy processing with faster crystallization, providing high stiffness and increased throughput.
Advantages of Ultradur® B 6550 LN:
- High melt stability for easy processing
- Excellent chemical resistance
- Low coefficient of thermal expansion
- Very low moisture absorption
- Dimensionally stable
- High stiffness and hardness
Ultradur® B 6550 LNX - faster processing, small diameters
- Specifically developed for FOC microtubes of ≤ 1.4 mm diameters
- Improved mechanical properties at low thicknesses
- High molecular weight and high viscosity
- Excellent feeding behavior and processability with high melt stability
