How to identify high-quality Basalt Fiber Insulated Zone

There are many ways to identify high-quality Basalt Fiber Insulated Zone. First look at the appearance. High-quality products have a smooth surface, evenly distributed fibers, no obvious burrs, damage or impurities, and a uniform dark brown or black color. If the color is dull and mottled, the quality may be poor.
Touch it with your hands. High-quality insulation has a tight texture, good flexibility, can be easily bent and is not easy to break. If it feels rough and loose, it breaks when bent, indicating that the fiber is not tightly combined and the quality is poor.
Then check the thermal insulation performance. You can wrap it outside the hot water cup and feel the outer wall temperature after a period of time. High-quality products have good thermal insulation effect and low outer wall temperature; if the outer wall gets hot quickly, the thermal insulation is poor.
In addition, it is also critical to understand product certification and test reports. High-quality Basalt Fiber Insulated Zone produced by regular manufacturers will pass relevant quality tests and have reports issued by authoritative organizations. Various performance indicators will be clearly marked on it, such as temperature resistance range, tensile strength, etc. Products that meet the standards are more trustworthy.
