Graphite Insulation Board for High Temperature Furnace
Product Overview
Jincheng graphite insulation boards for high temperature furnaces are precision-machined graphite panels designed for thermal insulation and radiation shielding in vacuum and atmosphere-controlled furnaces. These boards provide excellent thermal stability and high-temperature performance for efficient furnace operation.
Our furnace insulation boards are manufactured from high-density, fine-grain graphite that can be machined to precise dimensions for perfect hot zone fit. Custom thicknesses and panel sizes are available to match different furnace designs and insulation requirements.
Key Features
- Excellent high temperature stability up to 2800°C in inert or vacuum atmospheres

Frequently Asked Questions
Q1: What thickness insulation board should I use?
A: Insulation board thickness depends on your furnace temperature, hot zone diameter, and energy efficiency requirements. Please provide your furnace specifications for a recommended insulation design.
Q2: How long do graphite insulation boards last?
A: Board life depends on furnace temperature, atmosphere, and operating conditions. Under typical vacuum furnace conditions, graphite insulation boards last 2-5 years before needing replacement.
Q3: Can you machine custom shapes and cutouts in the boards?
A: Yes, we can machine custom shapes, holes, and cutouts in insulation boards based on your drawings and hot zone design requirements.
Q4: How do graphite insulation boards compare to graphite felt insulation?
A: Graphite boards provide better structural support and dimensional stability compared to graphite felt, but felt provides better thermal insulation. Many furnace designs use both: graphite boards for structural support and graphite felt for insulation.
