Effects of accelerators on the cure characteristics
The effects of different accelerators on the cure characteristics and mechanical properties of sulphur-cured natural rubber (NR)-based compounds are investigated. Three accelerator systems, with mercaptobenzothiazole disulphide (MBTS) as primary accelerator and diphenylguanidine (DPG) and Zn-2-mercaptobenzothiazole (ZMBT) as
(PDF) Effects of accelerators on the cure characteristics
The effects of different accelerators on the cure characteristics and mechanical properties of sulphur-cured natural rubber (NR)-based compounds are investigated.
The Blending of EPDM/NR with Maleic Anhydride as
The cure characteristic, mechanical properties, and morphology of the composites had been investigated by rheometer, tensile testing machine, hardness durometer and scanning electron microscope (SEM). Blending of EPDM/NR with various accelerator gave different composite characteristics.
The Effect of Accelerators on Curing Characteristics
The curing characteristics were estimated using oscillating disk rheometer. The results revealed that the accelerator type not only affects the cure characteristics, but also has great influence on the mechanical properties of obtained elastomers.
Cure characteristics and mechanical properties of different
In this study, the effect of different accelerators on cure characteristics and mechanical properties of natural rubber vulcanizates for the thick rubber article was investigated. The types of accelerators that were selected are N-cyclohexylbenzothiazole-2-sulphenamide (CBS), zinc diethyldithiocarbamate (ZDC) and diphenylguanidine (DPG).
Optimization of accelerators on curing characteristics
The effect of accelerator type on curing characteristics, tensile properties, and dynamic mechanical properties of 70/30/NR/(R-EPDM) blend was investigated. Influence of curing systems on cure
The Effect of Patient Characteristics on Acupuncture
OBJECTIVES: To optimally select chronic pain patients for different treatments, as it is of interest to identify patient characteristics that might moderate treatment effect. Our aim was to evaluate the impact of possible moderators on the effect of acupuncture treatment using a large data set.

On the structure and cure acceleration of phenol–urea
The cure-acceleration effects of catalysts on chemical structure and cure characteristics of PUF resins were investigated by using both liquid 13 C nuclear magnetic resonance (NMR) and differential scanning calorimetry (DSC).
(PDF) Effect of accelerators and stabilizers on the formation
The effect of thiourea, succinic acid and lead acetate on the formation and characteristics of electroless Ni–P deposits obtained from an acidic hypophosphite reduced electroless nickel bath is addressed in this paper.
The effects of bioactive components from the rhizome
Alzheimer’s disease (AD) is a common human neurodegenerative disease, which is characterized by the progressive loss of memory and the cognitive impairment. Since the etiology of AD is still unknown, it is extremely difficult to develop the effective drugs for preventing or slowing the AD process. The major characteristics of AD such as amyloid β plaques, neurofibrillary tangles
The effect of metal oxide on the cure, morphology, thermal
This paper discusses the role of metal oxides (MeO) in the cross-linking process and useful properties of chloroprene and butadiene rubber (CR/BR) blends. Iron(III) oxide (Fe2O3), iron(II,III) oxide (Fe3O4), silver(I) oxide (Ag2O) or zinc oxide were used. It has found that every proposed metal oxide can be used as a cross-linking agent of the CR/BR blends. The degree of cross-linking was
