Product Description

Products Description

Express Delivery Graphite Sealing Solutions

Advanced Material Production

Our expanded graphite materials—including flexible sheets, foil, paper, tape, and strips—are manufactured using a proprietary exfoliation process. Natural graphite flakes undergo chemical intercalation and high - temperature expansion (forming worm - like structures with 0.003g/cc density), then are rolled into binder - free coils. This vertically integrated production chain ensures consistent quality and rapid order fulfillment.
