Pre-dispersed Rubber Accelerators TBzTD-70GE

N-Nitrosamine Free Pre-dispersed Ultra Accelerator TBzTD-70 Environment-friendly rubber accelerator TBZTD masterbatch  Polymer bound rubber additives TBZTD-70  C30H28N2S4 M.W.: 554.82 CAS: 10591-85-2 EINECS: 404-310-0 PROPERTIES: TBzTD can lead to high processing safety and faster cure rate as an accelerator of natural rubber and synthetic rubber vulcanization. TBzTD satisfies requirements of[Technical Regulations for Dangerous Materials" TRGS 552 about toxicity of nitrosamines in Germany and not release carcinogenic nitrosamines during vulcanization. Addition of thiazoles or sulfenamides accelerators can slow the vulcanization, shorten scorching and vulcanization time and vulcanization without significant increases . It can be activated by alkaline accelerators such as aldehyde- amines and guanidines. DOSAGE: 0.2-2.0phr with 0.9-2.8phr sulfur. TYPICAL VALUES: Melting point: Min 128℃ Purity: Min 96% Ash content: Max 0.3% Heating loss content: Max 0.3% 6…
