Usage
TBBS is natural rubber, butadiene rubber , isoprene rubber, styrene-butadiene rubber and reclaimed rubber aftereffect accelerator, especially for carbon black with a strong alkaline compound . Safe operating temperature , anti- scorch resistance, curing speed, high elongation strength. In low sulfur vulcanization can be used alone , but also with two dithiocarbamate or thiuram accelerators and use the resulting vulcanized rubber has good aging resistance and modulus . Low toxicity and high efficiency, is an ideal alternative NOBS , with excellent performance , is called the standard accelerator. Widely used in the production of radial tires. Amines with aldehydes can , guanidine , thiuram accelerators and use, and scorch retarder PVI when used , constitutes a good vulcanization system. Mainly used in the manufacture of tires , rubber shoes, hose, tape, cable.
NR: 0.5 ~ 1.0 parts TBBS and sulfur and 2.5 to 3.5 parts by ;
SBR: 1.0 ~ 1.5 parts and 0.2 parts TBBS thiuram accelerators and sulfur of 1.5 to 2.5 .
