Thermoplastic Natural Rubber (TPNR)
Thermoplastic natural rubber (TPNR) is produced by dynamically vulcanizing natural rubber within a thermoplastic matrix, creating processable pellets for injection molding. The chemically cross-linked blend qualifies as a modified natural polymer in primary pellet form. It falls under this tariff item for natural polymers not elsewhere specified.
