China Expandable Graphite For Sealing
Shandong Sungraf Carbons Co., Ltd supplies industrial‑grade expandable graphite designed for sealing and gasket applications. The material is an intercalated graphite with a carbon content ranging from 80 % to 99 %. When heated, it expands to a volume of 200 - 350 ml per gram, providing the inflation needed for intumescent seals. The product is shipped in standard 25 kg bags or larger jumbo sacks, as stated in the supplier’s export packaging description.
Expandable graphite of this grade is commonly used in fire‑stop seals, pipe‑flange gaskets and intumescent coatings across the chemicals and advanced materials sectors. Typical commercial grades exhibit a bulk density of 0.6 - 0.9 g cm⁻³ and a thermal conductivity of 30 - 50 W m⁻¹ K⁻¹, values that align with the supplier’s claim of high thermal resistance. The material’s resistance to acids, bases and solvents makes it suitable for harsh environments found in automotive and aerospace manufacturing. Standard industry specifications require a moisture content below 1 % and a particle size distribution centred around 150 - 300 µm, which suppliers usually verify before packaging.
Buyers such as gasket manufacturers, fire‑protection system integrators and oil‑field equipment producers source this graphite for its reliable expansion on exposure to heat. The supplier offers flexible trade terms, including CIF and FOB, and accepts bulk orders that can be packed in either 25 kg bags or jumbo sacks for container loading. Importers should confirm the exact MOQ and any custom specifications directly with Shandong Sungraf Carbons before finalising the contract. Payment is typically arranged via T/T or L/C, with the possibility of negotiating credit terms after a satisfactory first shipment.
