The expansion volume is consistent, forming a strong, insulating char layer. It's highly effective and environmentally friendly compared to traditional options. Highly recommended for anyone in the fire safety materials industry.

This is our first order of expandable graphite for R&D purposes. The product arrived well-packaged and dry. The technical data sheet provided was accurate. We tested the expansion ratio under high heat, and it matched the manufacturer's claim closely. The flake size distribution was good. Customer service was responsive to our pre-sale inquiries. Will order again for our larger batch production.
