Bulk Pro-1600
Polycrystalline fibres are made from high purity aluminium. A special extrusion process provides the highest degree of chemical purity and the lowest level of defibering. The processing of the fibres ensures that they are extremely resistant to shrinkage and chemicals at high temperatures, while maintaining high flexibility and resilience. Bulk Pro 1600 are designed for temperatures up to 1600 °C.
