How To Distinguish High-quality And Low-quality Basalt Fiber Insulated Zone

Basalt Fiber Insulated Zone is widely used in industry, construction and new energy fields due to its excellent high temperature resistance, fire resistance and heat insulation performance. However, the quality of products on the market varies. How to distinguish the good from the bad? It can be judged from the following aspects:
1. Observe the appearance and texture
The fibers of high-quality products are evenly distributed, the surface is flat, and there are no obvious impurities or loose fibers; inferior products may have messy fibers, uneven thickness, and even contain unmelted particles.
2. Test high temperature resistance
Real Basalt Fiber Insulated Zone can withstand high temperatures above 700℃ for a long time. When burned briefly with a high temperature flame, high-quality products will not burn or deform significantly, while inferior products may carbonize, smoke or release odors.
3. Check flexibility and strength
High-quality insulation is flexible and not easy to break after repeated bending; inferior products may be brittle and hard, and easy to break or fall off when folded.
It is recommended to choose a well-known brand when purchasing, and ask for a test report to avoid affecting the safety of use due to the purchase of inferior products at a low price.
