Are PU stone panels suitable for humid environments or high temperature environments?

PU (polyurethane) stone panels are suitable to some extent in humid or high-temperature environments, but this depends on their specific manufacture and design.

Humid environment:

PU stone panels usually have a certain degree of waterproof performance and can resist moisture and water vapor in some humid environments. However, it should be noted that long-term exposure to moisture, especially immersion in water, may cause the panel to become more absorbent, affecting its structure and appearance. Therefore, when selecting and installing PU stone panels, it is necessary to consider the impact of the humid environment on the material and take corresponding waterproof measures.
High temperature environment:

The PU material itself has certain high temperature resistance, but the impact of its surface treatment and backsheet material needs to be considered. In a high temperature environment, it may cause the PU material to soften or deform, especially when it approaches or exceeds its temperature range. Therefore, when choosing PU stone panels, you need to choose high-temperature-resistant materials and combine them with appropriate fire-proof treatments to ensure their stability and safety in high-temperature environments.
For humid environments or high-temperature environments, choosing PU stone panels requires evaluation and selection based on specific circumstances to ensure that they meet environmental requirements and take necessary protective measures to extend their service life. In humid environments, special attention needs to be paid to waterproof performance; in high temperature environments, high temperature resistant materials need to be selected and appropriate fire protection treatments are required.
