The basalt yarn uses basalt roving with filament diameter of 7um and 9um then be twisted in 60-100 per meter.Usually,the twist direction is Z or S.This yarn can be used to produce basalt fabric.
l Electric insulating yarns and threads
l Unidirectional fabrics with high temperature resistance, high elastic modulus, and high strength
l After the special surface treatment, the yarn for Weaving fabrics with radiation resistance and heat resistance at (650-980℃)
l Good electrical insultion and mechanical properties
l Excellent tensile strength and modulus
l High temperature resistance from 650 ~ 980℃ of been woven into fabrics
l Uniform tension, good gatheringe
*Specific products could be made according to customers’requirements.
