In this method, an extract of vulcanized rubber is analyzed. The polymeric component is identified by evenly spaced clusters of mass spectral peaks. In addition, a chemical component is suspected to be
ISO 1396:1975 Vulcanized and unvulcanized compounded rubber — Determination of copper content — Zinc diethyldithiocarbamate photometric method ISO/PRF 3483 Copper and zinc sulfide
FT-Raman spectroscopy, coupled with spectral subtraction techniques, also has the potential to enable us to study blooms (vulcanization residues or antidegradent components that
In other words, rubber characterization on the basis of terahertz wave and ATR-FTIR spectroscopy might have high error, since the tests are done
Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural
The accelerated sulfur vulcanization of silica-filled natural rubber (NR) was investigated to determine the optimal concentration of vulcanization accelerator. Silica-filled NR containing 50 phr of
We present an advanced spectroscopic method to chemically analyze the vulcanizing system in rubber under ambient conditions, and we
In this work, the degree of cis-trans isomerisation of BR during its vulcanization and the influencing factors were systematically investigated using in-situ FTIR spectroscopy for different
In particular, novel evaluation methods for essential rubber products are being developed. THz absorbance spectra of various rubber polymers and reagents enable visualization of filler dispersions

Introduction What we call rubber contains many types of components. Some products contain a single component, while others contain a mixture of two or
In this work, we developed a new method for the determination of vulcanization accelerators and antioxidants based on Fourier Transform Infrared spectra of the CCl 4 extracts of
The properties of natural and synthetic rubber critically depend on the concentration of the vulcanizing system, among others. Sulfur and zinc
Rubber, also called India rubber, latex, Amazonian rubber, caucho, or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene,
INTERNATIONAL STANDARD ISO 6502-1 Rubber — Measurement of vulcanization characteristics using curemeters —
THz absorbance spectra of various rubber polymers and reagents enable visualization of filler dispersions and vulcanization reactions. Here, improved visualization of the vulcanization reaction in
4. Results and discussion To make a comparison between the conventional natural rubber compound that was investigated previously and the new compound with a Semi-efficient
4. Conclusions FT-IR spectrometry in combination with multivari- ate (PLSR) calibration enables the determination of some accelerators and antioxidants added to rubber prior to vulcanizing
In this work, a method for analysis of vulcanization accelerator in vulcanized rubber was developed by using a pyrolyzer (Py)-gas chromatograph/atomic emission detector (GC/AED) and
he unaccelerated vulcanization system is not used for commercial purposes. The mostly applied vulcanization system in the industry is accelerated sulfur vulcanization systems, which are classified
The effect of vulcanization on the far infrared spectrum of natural rubber can be summarized as follows: Vulcanization with sulfur alone produces no new bands,
Abstract A study on the effects of the curing systems on the dynamics and network structure of Natural rubber (NR) is performed by using broadband dielectric spectroscopy (BDS) and
The transient radar method (TRM) is introduced as an alternative for vulcanization monitoring in this study. Three polyurethane-rubber samples with different curing times of 2, 4, and
Characterization of vulcanized rubber after aging 96 hours, A, B, C, and D, using FTIR can be seen on Figure 6.
