Use Characteristics
TBBS-80 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-80 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-80 in combination with thiuram and dithiocarbamate is noticeably reduced. Thiourea has a strong secondary acceleration effect on TBBS-80, mainly in mixes containing little sulfur. In compounds which are accelerated with mercaptanes and thiurams, TBBS-80 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: 0.5-1.0phr with 2.5-3.5phr sulfur; secondary: 0.5phr with 1.5-3.5phr sulfur and 0.3phr mercapto or thiuram accelerator;
SBR: 1.0-1.4phr with 1.5-2.5 sulfur and 0-0.2phr thiuram accelerator.
Applications: Mechanical articles of all kinds, e.g. treads, carcasses, air hoses, conveyor belts, transmission belts, hoses, cable insulations.
Packing: Net weight 25kg/PE bags lined carton; Net 600 kg/pallet. Pallet size: 1.1x1.1x1m
Storage: In original closed containers under cool and dry conditions max.2 years.
Handling: Consult material safety data sheet (MSDS) for additional handling information.
