Use Characteristics
TBBS**0 is delayed action accelerator for NR, IR, BR, SBR, NBR, and
EPDM. It is suitable used for high temperature kneading and
provides a considerably long scorch time, great processing safety
and a fast full cure. TBBS**0 is used as an independent accelerator
for the low sulfur vulcanization or together with dithiocarbamate
or thiuram accelerators. The vulcanizates obtained have good ageing
resistance and good moduli. The curing rate of mixes containing
TBBS**0 in combination with thiuram and dithiocarbamate is
noticeably reduced. Thiourea has a strong secondary acceleration
effect on TBBS**0, mainly in mixes containing little sulfur. In
compounds which are accelerated with mercaptanes and thiurams,
TBBS**0 may delay scorch.
Processing Advantages
The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easy quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective TBBS is assured.
Dosage:
NR: primary: 0.**1.0phr with 2.**3.5phr sulfur; secondary: 0.5phr
with 1.**3.5phr sulfur and 0.3phr mercapto or thiuram
accelerator;
SBR: 1.**1.4phr with 1.**2.5 sulfur and **0.2phr thiuram
accelerator.
Applications: Mechanical articles of all
kinds, e.g. treads, carcasses, air hoses, conveyor belts,
transmission belts, hoses, cable insulations.
