Expandable Graphite
the use of special chemical treatment can be made of expanded graphite, with high visibility, good expandability and size distribution, swelling degree of balance, stability, and so on. For the low temperature expandable graphite, the company has high technical advantages, can be seasonal produce, has a stable customer.
Produced mainly for the production of expandable graphite flexible graphite sheet, with low sulfur content (S ≤ 1000PPM), high tensile strength (Tensile strengh ≥ 4.5MPa/CM2), body density uniform, smooth surface sheet and high quality of products stable. Low-temperature expandable graphite has a low expansion high multiples, expansion efforts, product quality and stability and so on, mainly applies to produce all kinds of fire-retardant material.
