从China供应商批发进口Akd Wax — FOB条款

AKD wax from Wuxi Founder Chemicals Co., Ltd. is supplied as a pale yellow waxy flake solid, the raw material precursor for manufacturing AKD emulsion sizing agents used in paper manufacture. The material is specified as an alkyl ketene dimer with C14-C18 alkyl chain composition, the standard carbon distribution for commercial AKD waxes that determines reactivity, melting point, and final emulsion stability. In flake form, it represents the unemulsified active ingredient that paper chemical mills or specialised emulsion producers process into pumpable liquid products for direct machine addition. The flake form offers longer shelf stability than finished emulsions and reduces transport costs by eliminating water content.

The C14-C18 alkyl chain composition is critical to performance: shorter chains (C14-C16) yield lower melting points and faster emulsification but potentially reduced hydrophobic efficiency, while longer chains (C18, stearic) improve water resistance but raise melting points and processing energy requirements. Standard commercial AKD wax typically carries an iodine value (I2) below 5 g/100g, indicating low unsaturation and better colour stability, and an acid value below 5 mg KOH/g, which reflects minimal free fatty acid content that could interfere with emulsion stability. The supplier emphasises high content and low acid without specifying figures, so confirmation of assay (typically 85-90% minimum AKD content) and acid value is essential for buyers formulating their own emulsions.

This AKD wax serves paper mills that operate captive emulsion plants, independent emulsion manufacturers, and distributors who blend and stabilise products for regional paper industry supply. Applications span writing paper, printing paper, and board products where internal sizing controls ink feathering, dimensional stability, and liquid resistance. Buyers should confirm the exact iodine value, acid value, melting range, and assay percentage with the supplier, as these parameters govern emulsion formulation and final paper performance. The physical form (flake size, bulk density) and packaging format, whether in 25 kg bags, supersacks, or bulk containers, also affect handling and storage infrastructure requirements.

Wuxi Founder Chemicals Co., Ltd. is located at No. 1011 of Columbus Square, 311 Guangnan Road, Wuxi, Jiangsu Province, China. The company operates under a harbor trust tier with a response rate of 0.00% and no recorded average response hours, suggesting limited platform engagement. The physical address places it in the Wuxi industrial corridor, a region with established chemical manufacturing and logistics infrastructure. No information on company history, founding year, production capacity, employee count, or revenue is provided in the source data.

The supplier's product focus is on AKD wax as a neutral sizing agent raw material, positioning itself as a feedstock provider to the paper industry rather than a formulated emulsion supplier. The emphasis on toluene-free and benzene-free production aligns with environmental and safety trends in paper chemical manufacturing. Buyers should verify whether Wuxi Founder Chemicals manufactures the AKD wax directly or acts as a trader, and whether the facility holds ISO 9001 or environmental management certifications. The lack of response signal suggests that direct outreach to the Wuxi address or through industry channels may be more effective than platform enquiry for technical discussion and sample requests.
