Effect of Non-Rubber Components on Properties of Sulphur
Non-rubber components (mainly proteins and lipids) in natural rubber (NR) play important roles for controlling the properties of NR. Crosslinking process creates intermolecular chemical bonds in order to obtain a three-dimensional network, resulting in more elastic rubber.

Characteristics of mechanical properties of sulphur cross
Roles of non-rubber components in guayule and dandelion natural rubbers on the mechanical properties of each sulphur cross-linked rubber are revealed for the first time by analysing the Mullins effect, dynamic mechanical properties and strain-induced crystallization (SIC) from a new viewpoint, in comparison with sulphur cross-linked Hevea natural rubber (S-NR) and synthetic isoprene rubber (S-IR). Physically aggregated non-rubber components, particularly proteins, work as “natural ...

Curing Parameters and Mechanical Properties of NR/SBR Blends
The crosslinks can be introduced between polymer chains by using different types of vulcanizing agents. Sulphur and organic peroxides are the two commonly used vulcanizing agents. A mixture of Sulphur and peroxide produces mixed crosslinks. Raw rubber or non-polar (SBR) has poor phyisco-chemical properties.

Effect of non-rubber components on the mechanical
Abstract. The nanomatrix of the non-rubber components was found to be inevitably formed in natural rubber, in which natural rubber particles linking to fatty acids were dispersed in the nanomatrix of the proteins and phospholipids. The nanomatrix disappeared after deproteinization of natural rubber with urea.

A model study on effect of glucose on the basic
The Maillard reaction between glucose and CBS reduces the accelerators in the sulfur vulcanization system, leading to the change of accelerator/sulfur ratio which influences the cure characteristics, crosslink density, tensile and dynamic properties of sulfur vulcanizates, whereas glucose shows no effect on the physical properties of peroxide vulcanizates.

Study of the Effect of Systems of Vulcanization
Abstract: Dynamic vulcanization of natural rubber (RSS) was studied. The effect of methods of vulcanization, i.e. sulphur, sulphurless and peroxide on mechanical, rheological properties, thermal ageing and weathering tests were investigated. Swelling behavior of when using sulphur, sulphurless and peroxide were investigated. Accelerators of mercapto class gave medium scorch time they gave ...

Non-rubber components tuning mechanical properties
NR consists of approximately 94% cis-1, 4-polyisoprene (PI) and 6% non-rubber components (NRC) such as proteins, phospholipids, and so on [, , ]. NR exhibits excellent properties such as high tensile strength, high tear strength, and superior puncture resistance.
