Influence of accelerator type on properties of NR/EPDM
Influence of accelerator type on properties of NR/EPDM blends. The results reveal that the accelerator type not only affects the cure characteristics, but also has great influence on compound viscosity. Among the accelerators studied, TBBS gives the best processing safety together with a relatively high state of cure.

Influence of accelerator type on properties of NR/EPDM
The effect of accelerator type on processability and mechanical properties of 60/40 natural rubber/ethylene propylene diene monomer (NR/EPDM) blend was investigated. Three groups of commercial accelerators were selected, i.e., sulfenamide group (Santocure-TBBS), thiuram group (Perkacit-TMTD) and mercapto group (Perkacit-MBT and Perkacit-MBTS).

The Blending of EPDM/NR with Maleic Anhydride as
In this work, the influence of accelerator type on cure characteristics and mechanical properties of 60/40 EPDM/NR blend was investigated. The compounds were prepared by controlling the migration of curative and using maleic anhydride as the compatibilizer.

VESTENAMER® in rubber compounds - Additive for the rubber
In blends with faster curing rubbers like NR, IR or BR the accelerator level can be slightly increased. Blends of EPDM with VESTENAMER® are normally cured with peroxides since sulfur curing can deteriorate the properties of the vulcanisate. VESTENAMER® has an influence on the physical properties of the cured compounds .

Diene Termonomer Type and EPDM Properties | Rubber
The objective of this work was to study the effects of the type of diene termonomer on properties, especially thermal stability and aging, of EPDM polymers. Five different EPDM polymers using ethylidene norbornene (ENB), butadiene (BD), dicyclopentadiene (DCPD), methyltetrahydroindene (MTHI), and 1,4-hexadiene (HD) as termonomers were made at ...

Effects of trans‐polyoctylene rubber (TOR)
trans‐Polyoctylene rubber (TOR) was melt blended with an incompatible NR/EPDM (70/30) blend.Mixing torque and temperature were reduced as TOR was added to NR/EPDM blend. The curing characteristics of the blend were affected as TOR participated in vulcanization and became a part of network.

Influence of Accelerator/Sulfur Ratio on Mechanical
This research investigated the effect of accelerator/sulfur (ACC/S) ratio on mechanical properties and thermal resistance of natural rubber composites containing hybrid fillers. Two hybrid systems of 10/60 carbon black/calcium carbonate (CB/CC) and silica/calcium carbonate (SC/CC) in NR composites were focused and the different ACC/S ratios were 0.40, 0.56, 0.64 and 0.88.

Vulcanization & Accelerators
requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C for completion, which is uneconomical by any production standards. The vulcanizates thus produced are extremely prone to oxidative degradation and do not possess adequate mechanical properties for practical rubber applications.
