从China供应商批发进口Akd Wax 1895/1865/1840 — FOB条款

Greatland Chemicals supplies AKD WAX 1895/1865/1840, a synthetic alkyl ketene dimer sizing agent manufactured for paper and board producers requiring controlled hydrophobicity in alkaline conditions. The three coded grades, 1895, 1865, and 1840, provide graduated performance profiles for different furnish types and end-use requirements. This wax functions by reacting with cellulose hydroxyl groups under alkaline pH to create permanent water-resistant ester linkages on fibre surfaces. The product originates from Weifang in Shandong Province, a region with established chemical manufacturing infrastructure located between Qingdao and Yantai ports.

The material is formulated as an industrial-grade wax with stated emphasis on purity and batch-to-batch consistency for coated and uncoated paper applications. Typical AKD wax for paper sizing contains 85-90 percent active dimer, with alkyl chain lengths predominantly in the C16-C18 range for higher grades and C14-C16 for lower melting variants. The 1895 grade typically exhibits denser stearyl content and elevated melting behaviour, while 1840 offers softer characteristics with greater myristyl proportion. Standard physical form is an off-white to pale yellow solid at 20 degrees Celsius, with mild fatty odour, melting to a low-viscosity liquid suitable for emulsification. The product is compatible with modern alkaline and neutral papermaking systems, including those using calcium carbonate filler, and does not require alum for fixation.

Primary buyers include manufacturers of liquid packaging board, food service packaging, label papers, and specialty grades where internal sizing eliminates the need for surface treatment or laminated barriers. The wax improves printability by reducing water absorption and feathering of inkjet and offset inks. Application requires emulsification to sub-2-micrometre particle size before addition at the fan pump or headbox. Greatland Chemicals offers bulk supply packaging, though exact container types and volumes require direct confirmation. Buyers should verify with the supplier their specific grade recommendations based on target Cobb values or HST seconds, together with technical support for emulsion formulation and wet-end stability.

Greatland Chemicals is based in Weifang, Shandong Province, China, a city located in the central Shandong peninsula with access to both Qingdao and Yantai seaports. The company's trust tier is listed as harbour, with no response rate data or average response time recorded in the available profile. The supplier address provided is incomplete, showing only the city, province, and country without street address or postal code detail. Weifang hosts a significant concentration of chemical and petrochemical enterprises, though this does not independently verify Greatland Chemicals' manufacturing status or capacity.

The supplier profile contains no information regarding year of establishment, registered capital, factory certification, employee numbers, annual turnover, or named customers. No ISO quality management certification, environmental compliance documentation, or export licence details are stated. The source description characterises the company as offering AKD wax for the paper chemicals sector, with claims of stringent quality controls and certification by relevant authorities, though no certifying body or standard is named. Buyers should independently verify Greatland Chemicals' manufacturing credentials, request factory audit reports, and confirm whether the company produces AKD wax directly or sources from third-party manufacturers.
