Polycrystalline Mullite Blanket VS Standard Insulation Materials
Not all high-temperature insulation products are created equal. Here is how polycrystalline mullite blanket compares to the main alternatives:
| Property | PCW | Standard RCF | Soluble Fiber Blanket |
|---|---|---|---|
| Max Service Temp. | 1600°C | 1260°C | 1200°C |
| Thermal Shrinkage | Very Low (≤2%) | High (3–5%) | Medium-High (3–4%) |
| Flexibility | High | High | High |
| Thermal Conductivity | Low | Low-Medium | Low-Medium |
| Chemical Stability | Excellent | Good | Fair (Vulnerable to strong acids/alkalis) |
| Health & Safety | Standard handling | Regulated in some regions | Eco-friendly/Body-soluble |
| Price (relative) | Medium-High | Low | Medium-Low |
| Best Application | >1400℃ continuous high-heat | <1200℃ standard insulation | Eco-conscious/Lower-heat applications |
