The Construction Grade Additive HPMC supplied by Shandong Haojian International Trade Co., Ltd. is a water‑soluble, non‑ionic cellulose ether identified as Hydroxypropyl Methyl Cellulose (CAS 9004‑65‑3). It appears as a white or off‑white powder and contains 5 wt % residual moisture, 28.0‑30.0 wt % methyl groups and 4.0‑12.0 wt % hydroxypropyl groups. The product delivers a viscosity range of 400‑200 000 mPa·s measured in a 2 % solution at 20 °C and forms a gel between 58 °C and 65 °C. The supplied batches meet a fineness of 80‑120 mesh and are packaged in 25 kg PP bags with optional bulk bags.
The additive conforms to typical construction‑grade HPMC standards, where a neutral pH of about 7 ± 1 is expected for a 1 % solution at 25 °C. Such grades are widely used to enhance water retention, workability and sag resistance in cement‑based mortars and grouts. Compared with standard industry grades, the listed methyl and hydroxypropyl contents fall within the usual range for high‑performance admixtures. The supplier notes that the product is stored in a cool, dry environment and retains its properties for up to twelve months.
Primary users include mortar manufacturers, tile‑adhesive producers and contractors preparing self‑leveling screeds. Shandong Haojian International Trade Co., Ltd. offers the additive in bulk quantities and can arrange FOB or CIF terms from ports near Qingdao and Shanghai, subject to confirmation of order size. Buyers should verify the latest material safety data sheet and request a sample before finalising a purchase.

Before placing an order, importers should confirm Shandong Haojian International Trade Co., Ltd.’s business registration and request a current material safety data sheet. Because the platform profile shows no recent response activity, it is prudent to obtain at least one reference sample and verify the batch’s certificate of analysis. Ensure that the supplier can provide a reliable shipping schedule from the nearest port.
The additive is typically shipped in sealed 25 kg bags, with the possibility of bulk big‑bag containers for larger volumes. Exporters usually offer FOB or CIF terms from Qingdao or Shanghai, but exact incoterms and lead‑time must be agreed on directly with the supplier. Payment methods commonly include T/T against documentary evidence, though buyers should request the specific payment schedule before contract signing.
Importers are advised to arrange a third‑party inspection of the cargo at the loading port, focusing on moisture content, visual appearance and packaging integrity. Request a full certificate of analysis, test reports for viscosity and pH, and a compliance statement with any applicable construction‑chemical standards. Maintaining these documents will simplify customs clearance and guarantee that the product meets the performance requirements of your mortar formulations.
