Shandong Sungraf Carbons Co., Ltd

China‑based Shandong Sungraf Carbons Co., Ltd lists 66 active products across four main categories: Graphite, Carbon, Heat Exchangers and Refractory Bricks. The catalogue contains multiple grades of natural micronized and flake graphite, synthetic graphite powders for catalytic use, and a series of expanded and flexible graphite sheets identified under HS codes 2504.10, 2504.90, 3801.10, 3801.20, 3801.30, 3801.90 and 3824.99. Products such as Micronized Graphite, High Purity Pencil Lead Flake Graphite and Micronized Carbon Graphite for alkaline batteries are described with fixed carbon contents ranging from 80 % to 99.9 %. Additional items include custom graphite sheet/rolls, ultra‑low sulfur expandable graphite, and refractory bricks derived from natural flake graphite.

The supplier’s listing also mentions specialty items like High Thermal Conductivity Graphite Sheet (synthetic expanded pyrolytic graphite) and Fireproof Material - Expandable Graphite, both falling under HS chapter 38. The product titles frequently reference “high purity”, “best quality” and specific carbon percentages, reflecting the typical specifications buyers seek in graphite‑based materials. No additional company history, employee numbers or revenue figures are provided in the source data.

The catalogue covers natural micronized graphite powders (HS 2504.10/2504.90) with fixed carbon values between 80 % and 99.9 %, as well as synthetic graphite powders for catalyst applications (HS 3801.10). Expanded graphite products appear under HS 3801.20‑3801.30 and include flexible sheets with carbon content of 99 % + and ultra‑low sulfur variants used in sealing and gasket applications. Refractory bricks made from natural flake graphite are listed without an HS code but are typically classified under HS 2504.00 for graphite products used in high‑temperature environments. In the global graphite market, natural flake grades are often graded by particle size (e.g., - 40 µm, - 80 µm) and fixed carbon content, while synthetic or expanded grades are evaluated for bulk density (g cm⁻³), expansion ratio and electrical conductivity. Buyers commonly request ASTM D‑7342 for particle size distribution and ISO 9001‑based quality management documentation for these materials.
