Gum Rosin, X & WW Grade

PT. Istana Palapa Kertas offers gum rosin in the X and WW grades, a natural solid derived from oleo pine resin of Marcusii pine trees grown in Indonesia. The rosin appears yellowish and semi‑transparent, is insoluble in water and dissolves readily in most organic solvents. The supplier specifies shipment in a standard 20‑foot general‑purpose container with a net weight of 19 metric tonnes per container. Trade can be conducted under CIF or FOB terms as agreed with the buyer.

X and WW grades are common classifications that indicate low acid value and high purity, making the material suitable for paper sizing and ink formulations. In the industry the acid value is typically below 0.5 mg KOH per gram, and the moisture content is usually under 0.2 % by weight. The softening point of standard gum rosin falls between 120 °C and 130 °C, and the melt flow index is generally in the range of 0.5 to 1.5 g/min. These typical parameters help manufacturers assess compatibility with their processes.

Buyers such as paper manufacturers, printing‑ink producers, automotive coating firms, electronics component makers, cosmetics formulators and batik artisans commonly use gum rosin for its adhesive and protective properties. The listed minimum order of one 20‑foot container allows bulk procurement for large‑scale production. Payment and shipping details, including exact lead time, should be negotiated directly with the supplier. Confirming the chosen Incoterm and any required documentation will ensure smooth customs clearance.
