Product Description TETD-75 is used as ultra-accelerator for NR, SBR, NBR, IIR, BR and latex. It is also used as vulcanizator for manufacturing cables, rubberized fabric, rubber shoes, inner tubes and colored products.


Processing Characteristics Generally, TETD  powder adheres to devices easily, disperses difficultly in mixing process. However, TETD-75has good dosing and mixing property, and won’t cake at ordinary temperature and humidity. It has good fluidity, no irritating dust and no material loss. It keeps optimal activity of TETDand easily disperses in kinds of rubber compounds.


Dosage As primary accelerator:                   

            NR:0.15~0.3 phr TETD-75 with 2.0~3.0 phr sulfur;

            SBR:0.25~1.5 phr TETD-75 with 2.0~3.5 phr sulfur;

             IIR:1.0~2.0 phr TETD-75 with 1.0~2.0 phr sulfur;

             NBR:0.1~3.0 phr TETD-75 with 0.5~2.0 phr sulfur 1.0~2.0 phr thiol;

             CR:0.5~1.0 phr TETD-75 with 0.5~1.0 phr sulfur and 1.0~3.0 phr guanidine.

             As assistant accelerator:

              NR:0.1~2.5 phr TETD-75 with 2.5 phr sulfur and 1.0 phr thiol;

              SBR:0.1~0.75 phr TETD-75 with 2.0~3.5 phr sulfur and 2.0 phr thiol.
