The insulation effect of "rock wool" is demonstrated by the fact that over 95% of its volume is occupied by air, which is divided into fine voids by fibers, making it difficult for the air to move. As the temperature of the air in the rock wool rises, it becomes more active, leading to a decrease in insulation performance with the increase in ambient temperature. However, the higher the density, meaning the greater the number of fibers per unit volume, the more resistance to air flow increases, preventing a decline in insulation performance. "Roxceram" excels in fire resistance and can be used as insulation material even in high-temperature areas of around 400°C, making it widely utilized under harsh conditions such as in plant equipment. For more details, please refer to the PDF download below. 【Insulation Performance by Temperature Range】 ■ Low Temperature Range (below 100°C) - It shows a minimum value with a density of 80-100 kg/m3, but there is no significant difference across the entire density range. ■ High Temperature Range (above 100°C) - Above 100°C, the thermal conductivity increases quadratically with rising temperature. - This trend becomes milder as the density increases. *For more details, please refer to the PDF document or feel free to contact us.
