从China供应商批量进口Akd Wax 1840/1865/1895

AKD wax 1840/1865/1895 from Amazon Chemicals Limited is a synthetic alkyl ketene dimer wax produced through the reaction of fatty acids with ketene, forming a complex molecule valued in paper and packaging applications. The three grade codes, 1840, 1865, and 1895, correspond to different alkyl chain distributions and melting points suited to varied sizing requirements. This product functions as an internal sizing agent, imparting hydrophobicity to cellulose fibres to resist water penetration without compromising sheet strength. The wax is supplied from Tianjin, a major northern Chinese port city with established chemical logistics infrastructure.

The typical composition of AKD wax comprises a mixture of alkyl ketene dimer molecules with C14-C18 alkyl chains, though exact distribution varies by grade. Grade 1895 typically exhibits a higher proportion of stearyl (C18) chains, yielding a wax with elevated melting point around 65-70 degrees Celsius, whereas 1840 contains more myristyl (C14) content for lower melting behaviour around 50-55 degrees Celsius. Standard industry purity for paper-grade AKD wax sits at 85-90 percent active dimer content, with the balance being stabilisers and processing aids. The material is supplied as a pale yellow to off-white waxy solid at ambient temperature, requiring controlled heating for dispersion in aqueous systems. Paper mills typically emulsify the wax with cationic starch or synthetic polymers before adding to the wet end of the paper machine.

Buyers of AKD wax from Amazon Chemicals Limited include integrated paper mills, specialty paper converters, and packaging board manufacturers seeking internal sizing for liquid packaging, food wraps, and label stock. The product is used in alkaline papermaking at pH 7.5-8.5, where it reacts with cellulose hydroxyl groups to form permanent beta-ketoester bonds. Sourcing from Tianjin offers access to Bohai Rim industrial corridors, though buyers should confirm with Amazon Chemicals Limited regarding exact MOQ, lead times, available Incoterms, and whether the supplier provides technical support for emulsion formulation.

Amazon Chemicals Limited operates from Room 1305, Huichuan Edifice, in the Binhai New Area of Tianjin, China. The Binhai New Area is a state-level new area and economic centre in northern China, hosting substantial petrochemical and port logistics infrastructure. The supplier's trust tier is listed as harbour, with a response rate of 0.00 percent and zero average response hours recorded, indicating no historical response data is available through this channel. The company address places it within Tianjin's 300457 postal district, a zone encompassing developed industrial and commercial zones rather than manufacturing estates.

The supplier profile carries no stated information regarding factory ownership, production capacity, year of establishment, employee count, annual revenue, or named clientele. No certifications, quality management systems, or export licence details are provided in the available data. Buyers should conduct independent verification of Amazon Chemicals Limited's manufacturing credentials, request references from existing paper industry customers, and confirm whether the company operates as a manufacturer, trader, or distributor. The absence of response history suggests proactive direct contact is essential before relying on this supplier for time-sensitive procurement.
