FAQ
1. What is the maximum temperature High Silica Fiber Chopped Yarns can withstand?
Engineered for extreme thermal shock, our High Silica Fiber Chopped Yarns support a long-term continuous working temperature of up to 1000°C. Furthermore, they are highly resilient and capable of withstanding short-term temperature surges of up to 1400°C. Combined with exceptionally low thermal conductivity, they act as the ultimate thermal barrier for severe industrial environments.
2. Why is the SiO₂ content important in these chopped yarns?
The performance of high-heat fibers is directly linked to their purity. Our high silica fibers are manufactured with over 96% Silicon Dioxide (SiO₂) content. This ultra-high purity is the key factor that provides the material with its stable chemical stability and prevents it from melting or degrading in extreme heat, far outperforming standard fiberglass materials.
3. What are the primary industrial applications for High Silica Chopped Yarns?
These specialized yarns are precision-chopped to specific lengths to serve as the premium raw material for the high-temperature nonwoven insulation industry. They are primarily utilized to manufacture high-temperature nonwoven insulation blankets and heavy-duty needle mats. These finished nonwoven products are then applied in automotive, aerospace, heavy metallurgy, and industrial furnaces where standard insulation would fail.
