How Is Technically Specified Rubber (TSR) Graded?
Quick AnswerTSR is natural rubber graded according to specified technical parameters; the grade serves as a preliminary screening basis, while actual procurement requires verification of the specific standard, producing factory, and batch COA.
Grading Basis
Technically Specified Rubber (TSR) specifications are built on laboratory-tested indicators. ISO 2000 provides specification guidelines; national grades and buyer-seller contracts may still set different requirements.
Trading-Level Limitations
The same grade does not automatically guarantee identical processing performance across different factories. The applicable contract version, batch data, packaging, and customer approval scope should be verified.
