Accelerator TBBS(NS)-80 , Light White Granule , Used for soles and other rubber products.
Recommendations and Applications:
TBBS is delayed accelerator of NR , BR , IR , SBR and reclaimed rubber ,
especially suitable for carbon black masterbatch containing strong alkaline ,
with well processing safety at operating temperature ,
excellent anti-scorching ability , fast curing rate and imparts high tensile modulus of vulcanizate.
In low sulfur vulcanization,
TBBS can be used either alone or along with dithiocarbamate salts and thiuram ,
imparts good aging resistance and modulus of the vulcanizates. With high efficiency and low toxin ,
it has excellent comprehensive performance, it is an ideal substitute for NOBS,
and called the standard accelerator.
Widely used to produce radial tyre. It can be used along with aldehyde amine , guanidine , thiuram ,
and as well as anti-scorching agent PVI , form a good vulcanization system. Mainly used in tires ,
rubber soles , rubber hose , belts , cable manufacturing.
NR: 0.5~1.0 PHR TBBS and along with 2.5~3.5 PHR sulfur
