Products classified under HTS 2909.49.30.00
High-Purity Dipentaerythritol Powder (99%)
Dipentaerythritol with 99% purity by weight, a polyol ether-alcohol derived from pentaerythritol, used primarily as a crosslinking agent in alkyd resins and polyurethanes. It falls under HTS 2909.49.30.00 due to its classification as a high-purity ether-alcohol meeting the 94%+ threshold in the ether-alcohols heading. This white crystalline powder is essential for high-performance coatings and adhesives.
Perstorp Di-Pentaerythritol Technical Grade (98%)
Commercial dipentaerythritol from Perstorp with 98% purity, a six-hydroxy polyether alcohol used in radiation-curing inks and lubricants. Classified under HTS 2909.49.30.00 as it meets the high-purity ether-alcohol criteria in heading 2909. This odorless powder enhances durability in UV-curable formulations.
Bimax Dipentaerythritol USP Grade (99.5%)
Pharmaceutical-grade dipentaerythritol at 99.5% purity from Bimax, used as an excipient stabilizer in polymer drug delivery systems. It qualifies for HTS 2909.49.30.00 as a pure ether-alcohol compound per Chapter 29 scope for chemically defined organics. This high-assay powder meets strict impurity limits for medical applications.
Synthomer DiPE 98% Crosslinker Grade
Synthomer's DiPE crosslinker at 98% purity, an ether-alcohol for thermoset polyester resins in composite materials. HTS 2909.49.30.00 applies as a chemically defined high-purity compound within ether-alcohols heading. Enables high-temperature resistance in molded parts.
Dipentaerythritol Flakes 96% Purity Industrial Pack
Dipentaerythritol supplied in flake form at 96% minimum purity for large-scale alkyd paint production. This ether-alcohol polyfunctional monomer fits HTS 2909.49.30.00 due to its ≥94% assay and Chapter 29 priority for pure organic compounds. Primarily used to improve film hardness in surface coatings.
