Calcium Silicate Product Range — 650°C to 1100°C
Every calcium silicate insulation board Mingfa manufactures falls into one of three temperature-defined categories. Understanding these categories helps you match the right calcium silicate product range to your operating conditions.
Standard Temperature
650°C
Calcium Silicate Pipe Sections & Molded Parts
Pre-formed pipe insulation sections and custom molded shapes for service up to 650°C. Standard calcium silicate board types for general industrial pipework, tanks, and vessels. Low thermal conductivity with excellent dimensional stability.
High Temperature
1000°C – 1100°C
LG-Standard & LG-High Temperature Series
Our flagship calcium silicate insulation boards for rotary kilns, furnaces, and high-temperature process equipment. LG-Standard (HCS series) handles 1000°C; LG-High Temperature (SCS series) reaches 1100°C — exceeding ASTM C533 Type II requirements at 927°C.
High-Density & Refractory
300–900 kg/m³
Composite Bricks & Refractory Boards
For applications where calcium silicate insulation board must carry structural loads. MF-HD high-strength boards, MFDJ composite bricks (aluminum industry), MFGB steel ladle bricks, and MFBL glass furnace bricks. Density ranges from 300 to 900 kg/m³ with compressive strength reaching 13 MPa.

How to Choose the Right Calcium Silicate Insulation
Selecting a calcium silicate insulation board does not need to be complicated. Follow these three steps to narrow down your options — or contact our technical team for a personalized recommendation.
Define Your Application
What are you insulating? The application dictates the product form factor and density class.
- Rotary kilns / furnaces → LG-Standard or LG-High Temp board
- Pipes & vessels → Calcium silicate pipe sections or standard boards
- Fire doors / barriers → GF-1100 fireproof board (A1 non-combustible)
- Structural / load-bearing → MF-HD or composite brick series
- Molten metal contact → LG-High Purity (non-stick to aluminum)
Match Your Temperature
Your peak operating temperature determines which calcium silicate board types are suitable.
- Up to 650°C → Standard calcium silicate pipe sections, molded parts
- 650°C – 1000°C → LG-Standard HCS series boards
- 1000°C – 1100°C → LG-High Temp SCS series or GF-1100
- Always add a safety margin — select a board rated at least 50–100°C above your peak operating temperature.
Select Density & Strength
Higher density means higher strength but also higher thermal conductivity. Balance these tradeoffs.
- 170–250 kg/m³ → Maximum thermal efficiency (lowest conductivity), non-load-bearing
- 300–600 kg/m³ → Moderate strength for light structural loads
- 800–900 kg/m³ → High compressive strength for load-bearing applications
- Unsure? We provide free technical consultation to help you find the optimal density for your specific requirements.
