Advanced Carbon Fiber Weaving

Our proprietary weaving process optimizes fiber orientation, delivering superior thermal insulation performance for our soft carbon felt, graphite felt, and rigid graphite felt board products.

Ultra-high Temperature Process

High temperature graphitization delivers high purity for our graphite and carbon fiber products, eliminating contamination risk to your vacuum furnace hot zone environments and processed workpieces.

Precision Custom Machining

Precision machining to your exact specifications ensures seamless on-site installation for vacuum furnace hot zone maintenance, reducing your assembly time and ongoing maintenance costs.

What Our Clients Say

We previously used rigid graphite felt laminated from multi-layer soft graphite felt for vacuum furnace insulation, and switched to Solid Carbon’s long fiber rigid graphite felt boards last year. The thermal insulation performance is significantly better, cutting heat-up time and reducing energy consumption to lower costs. We’ve been impressed with the quality, and placed repeat bulk orders for our projects.
