What are the international standards for PLUS ceramic fiber blankets? In the industrial field, “PLUS” usually represents a product that has undergone reinforcement treatment on the basis of ordinary ceramic fiber blankets (such as double-sided needle punching reinforcement, adding special binders, or using high-purity raw materials), with higher tensile strength, better abrasion resistance, and lower shrinkage rate. The “international index” of PLUS blanket is not a single standard number, but refers to a series of internationally recognized testing standards (such as ASTM, ISO) that the product complies with, as well as its key performance parameters.
| Physical Indicators – PLUS Blanket | 1260 blanket | PLUS Blanket | national standard |
| Operating temperature (°C) | 1000 | 1050 | 1000 |
| color | pure white | pure white | white |
| Bulk density (kg/m³) | 96-128 | 96-128 | 96-128 |
| Slag ball content (%) (particle size greater than 0.212 mm) | ≤20 | ≤5 | ≤20 |
| Thermal conductivity at various hot surface temperatures (W/m·K) (Volume density 128 kg/m³) | ≤0.153 (500℃) | ≤0.135 (500℃) | ≤0.156 (500℃) |
| Tensile strength (kPa) (Bulk density 128 kg/m³) | ≥34 | ≥110 | ≥21 |
The PLUS blanket ceramic fiber blanket from Rosewool Insulation Refractory Co.,Ltd. specifies the methods for measuring thickness, bulk density, rebound, heating permanent line change, thermal conductivity, tensile strength, and slag ball content. It is suitable for various ceramic fiber blankets, boards, paper and other products outside the dehumidification state.
PLUS blankets are classified according to temperature: internationally, ceramic fiber products are usually classified into four levels based on temperature, namely 1000 ℃ type, 1260 ℃ type, 1400 ℃ type, and 1600 ℃ type. These grades indicate the maximum temperature that ceramic fiber blankets can withstand in a short period of time, reflecting the heat resistance of the product.
The so-called “international indicators” refer to the physical and chemical requirements of ASTM C892 for high-temperature fiber blankets that the product must meet, and achieve high-performance levels (i.e. “PLUS” level) in tensile strength, linear shrinkage rate, and slag ball content. In practical engineering, it represents a high-end ceramic fiber needle punched blanket with a density of 128-192 kg/m ³, a classification temperature of 1260-1400 ℃, and excellent resistance to erosion and flexibility.
