Rubber accelerator TBZTD

Rubber accelerators TBZTD Chemical Name: benzyl disulfide four thiuram formula: C30H28S4N2 Molecular Weight: 544 CAS NO: 10591-85-2 Specification: Item Powder Dust powder particles appearance (visual) pale yellow powder (particles) Melting point ℃ ≥ 124.0 123.0 123.0 Loss on heating% ≤ 0.40 0.40 0.40 Ash% ≤ 0.30 0.30 0.30 sieve residue (150μm),% ≤ 0.10 0.10 \\\\ sieve residue (63μm),% ≤ 0.50 0.50 \\\\ oil content of 1.0-2.0% \\ \\ diameter, mm \\\\ \\\\ 1.5-2.5 Uses: Given the nitrosamine problem, develop alternative TBZTD similar TMTD of thiuram accelerator. According to the published literature indicates that dibenzyl not carcinogenic nitrosamine. This product is used as a fast primary and secondary accelerator in NR, SBR and NBR in. Better than TMTD processing safety, scorch longer. During vulcanization neoprene with NN ethylene thiourea and use, TBZTD used as retarders.
