Frequently Asked Questions

What is the difference between natural flake graphite and synthetic graphite?

Natural flake graphite is mined and processed from ore, offering high crystallinity and conductivity. Synthetic graphite is produced from petroleum coke through high-temperature graphitization, providing ultra-high purity and consistent particle size.

Can you customize graphite specifications?

Yes, we offer custom mesh sizes, carbon content, moisture levels, and packaging options based on your industrial requirements.

What are the main applications of expandable graphite?

Expandable graphite is widely used in fire-retardant coatings, intumescent materials, PU foam, and thermal insulation systems due to its high expansion ratio when heated.

Do you provide samples?

Yes, we offer free samples for qualified buyers. Please contact us through the official website to request a sample.
