We describe the synergistic activities of binary vulcanizing accelerators in presence of
magnesium oxide as cure activator in the vulcanization of natural rubber. Thiuram type …

Sulfur-rich polymers (SP) were prepared using styrene as a comonomer in inverse
vulcanization with elemental sulfur and used as a vulcanizer for Eucommia ulmoides gum …

The reversion during the curing and the poor thermal oxidative aging resistance of natural
rubber are two main problems for its use as a tire tread. To solve the problems, a …

The rheometer curing curves of neat natural rubber (NR) and neat chloroprene rubber (CR)
with maleide F (MF) exhibit considerable crosslinking torque at 180° C. This indicates that …

It is well known that high-temperature curing of natural rubber (NR) with a conventional
accelerated-sulfur (CV) system is limited because of reversion. This paper describes the …

The influence of rubber devulcanization by microwaves in the reversion behavior is still
modestly explored in the literature. The reversion occurs due to thermal degradation of …

The vulcanization of high diene elastomers with conventional or semi-efficient vulcanization
systems exhibit reversion at a higher temperature due to the breakage of the polysulfidic …

A high calcium oxide fly ash (FA), a by-product waste of electric power generation has been
used as hybrid activator in natural rubber (NR) composites filled with carbon black (CB). The …

Epoxidized natural rubber (ENR) is a relatively new raw material that can be used in many
applications, such as rubber-based adhesives, self-crosslinking, and compatibilization of …

Vulcanizates of chlorobutyl rubber (CIIR) with the accelerated sulfur generally exhibit poor
crosslinking density owing to the low level of unsaturation in the backbone of CIIR …
