Shandong Zhuo Jun Industrial Co., Ltd.

Shandong Zhuo Jun Industrial Co., Ltd. operates from Shandong Province, China, and lists 19 active products in its catalogue spanning industrial chemicals, plastic raw materials, construction chemicals, agricultural inputs, batteries and water treatment inputs. The supplier's portfolio is concentrated in polymer-based construction additives, with the largest group of items being redispersible polymer powders (RDP) and polyvinyl alcohol (PVA) grades used in dry-mix mortars, tile adhesives and renders. Secondary lines cover cellulose ethers (HPMC), polycarboxylate ether (PCE) and melamine-based superplasticizers, silicone water repellents, hydroxypropyl starch (HPS), and EVA emulsion powders, alongside adjacent categories such as glues and adhesives, agricultural inputs, batteries and water filters/water treatment plants.

The catalogue is anchored in HS code families 3905 (polymers of vinyl acetate or of other vinyl esters, in primary forms; other vinyl polymers in primary forms) and 3824 (chemical products and preparations of the chemical or allied industries), which together cover the bulk of the listed specialty additives. Specifically, VAE-based redispersible polymer powders fall under subheadings 3905.12 and 3905.29, PVA grades (including the partially hydrolyzed PVA 2488 type) sit under 3905.30, and the superplasticizer lines (melamine sulfonate and PCE) are classified under 3824.40. The supplier therefore presents itself as a chemical intermediates and construction-inputs exporter serving dry-mix mortar producers, tile adhesive manufacturers, and downstream buyers in the waterproofing and water-treatment segments.

The catalogue is built around four technical families. The first is redispersible polymer powder (RDP), a spray-dried VAE copolymer dispersion supplied in powder form for re-emulsification in water; the catalogue lists several RDP grades (including a ZJ-801 reference product) and a separate VAE RDP 801 line, all based on vinyl acetate-ethylene copolymer chemistry. The second family is polyvinyl alcohol (PVA), including PVA 2488, a partially hydrolyzed grade with a typical 88 mol% degree of hydrolysis and a viscosity around 48-52 mPa.s for the 2488 designation, widely used as a binder and film-former in mortars, paper coatings and adhesives. The third family covers cellulose and starch ethers: HPMC (hydroxypropyl methyl cellulose) for water retention in readymix mortar, and a hydroxypropyl starch (HPS) variant, both functioning as thickeners, water-retention agents and workability improvers. The fourth family is concrete and mortar admixtures: PCE (polycarboxylate ether) water reducers for ready-mixed mortar, and melamine formaldehyde sulfonate superplasticizers, which are sulfonated melamine condensates used as high-range water reducers in cementitious systems. Adjacent listings include dry-mortar tile adhesives, EVA emulsion powders, and silicone water repellents for hydrophobic surface treatment. Buyers in this category typically evaluate these products against established construction-chemical specifications: RDP powders are graded by polymer base (VAE being the most common for flexible mortars), minimum solids content of around 99%, ash content, minimum film-forming temperature, and redispersibility in water; PVA grades are specified by degree of hydrolysis (fully hydrolyzed 98-99% vs. partially hydrolyzed 87-89%), viscosity grade (e.g. 2488, 1799, 0588 nomenclature) and volatile matter; HPMC is graded by viscosity (commonly 100,000 mPa.s grades for mortar), methoxy and hydroxypropyl substitution, and gel temperature; PCE superplasticizers are specified by solid content (typically 40-50% liquid or 95%+ powder), water-reduction ratio (25-40% at typical dosage), and slump retention. These are the standard parameters buyers should expect to see on a technical data sheet for any of the listed items.
