Seng Fat (HK) Ent Ltd. offers caustic soda in the form of high‑purity sodium hydroxide flakes with a minimum assay of 99 % NaOH, as stated in the product description. The flakes are commonly packed in 25 kg bags and are suitable for bulk import in containerised shipments. This grade is widely used in paper pulping, textile processing, detergent formulation and petroleum refining where a solid alkaline source is required. The supplier highlights that the product complies with standard industrial specifications for purity and physical form.
Typical solid NaOH flakes have a bulk density of about 2.13 g cm‑3 and dissolve readily in water, producing solutions with a pH of roughly 13.5 at 1 % concentration. Standard storage calls for dry, airtight containers kept at 20‑30 °C to avoid moisture uptake, which can cause caking. The material is classified as hazard class 8 (corrosive) and must be handled with appropriate protective equipment and ventilation. Safety data sheets are normally issued on request, detailing handling and emergency measures.
Buyers generally import the product under FOB or CIF terms, loading the 25 kg bags into 20‑ft containers or larger bulk vessels. Since the listing does not disclose minimum order quantity, lead time or payment conditions, interested parties should confirm these parameters directly with Seng Fat (HK) Ent Ltd. Custom packaging or bulk IBC options can be discussed if the buyer’s logistics require it. The high purity of the flakes makes them a preferred choice for manufacturers seeking consistent alkaline performance in chemical synthesis and water treatment.

Arrange a third‑party pre‑shipment inspection to confirm purity, bulk density and absence of contaminants.
