Henan Daye Metallurgy Casting Material Co. Ltd.

Henan Daye Metallurgy Casting Material Co. Ltd. is based in China and currently lists 19 distinct products in its catalogue. The product list spans categories such as Agriculture, Other Ores & Minerals, Coke, Perlite, Light & Medium Machinery, Carbon and Coal. Items include Perlite Ore (HS 2530.10, volcanic glass perlite ore, unexpanded), Expanded Perlite, Closed‑Cell Perlite, Brilliant Expansion Perlite and Raw Perlite Ore, as well as Calcined Petroleum Coke and Calcined Anthracite Coal. The catalogue also features Graphite Carbon Additive, Graphitized Petroleum Coke Carbon Additive, Glass Microsphere (HS 7018.90, soda‑lime borosilicate hollow spheres) and Antipiping C (HS 3808.93, heat‑preservation coating compound). Additional entries such as Slag Remover, Floatert and New Type Floater complete the range without listed HS codes.

The listed products are grouped under six top categories, reflecting typical industrial uses from agricultural soil amendment to refractory carbon additives. Perlite products are offered in both raw ore and expanded forms, supporting applications in insulation, filtration and horticulture. Carbon‑based items such as calcined petroleum coke and graphite additives serve as fuel and conductivity enhancers in steelmaking and battery manufacturing. Glass microspheres are supplied for lightweight composites and acoustic damping. The presence of HS codes for three items indicates compliance with international customs classification, facilitating export logistics.

The perlite portfolio includes unexpanded volcanic glass ore (HS 2530.10) and several expanded variants such as Closed‑Cell Perlite and Brilliant Expansion Perlite. In the global market, unexpanded perlite is typically graded by particle size (2‑6 mm) and purity above 99 %, while expanded perlite is characterized by bulk density between 0.09‑0.20 g cm‑3 and a compression strength of 0.3‑0.5 MPa. These specifications suit applications in thermal insulation, horticultural growing media and oil‑well drilling muds. The catalogue’s expanded products align with these industry grades, offering bulk‑bag or 20 ft container packaging. Carbon‑rich offerings such as Calcined Petroleum Coke and Calcined Anthracite Coal are standard in the metallurgical and power‑generation sectors. Typical specifications include carbon content of 70‑90 % for calcined petroleum coke, ash below 5 %, and a volatile matter content under 2 %. Graphite Carbon Additive and Graphitized Petroleum Coke Carbon Additive are usually supplied with particle sizes of 5‑50 µm and a purity of 99.5 % carbon, meeting the requirements for electrode manufacturing and lubricant formulations. Glass Microsphere (HS 7018.90) is generally produced with diameters of 10‑100 µm, a hollow‑core density around 0.4 g cm‑3 and a silica content exceeding 95 %, making it suitable for lightweight composites and acoustic panels.
