theory & practice of vulcanization

Theory & Practice Of Vulcanization

Vulcanization, the process of crosslinking elastomers, occurs by a chemical process initiated through some form of energy input. It occurs between two statistically favorable reactive sites. Such sites are available through one or more of the following conditions: • Inherent. Double bonds in diene-containing elastomers. • Specific.

Vulcanization - an overview | ScienceDirect Topics

The vulcanization system constitutes the fourth component in an elastomeric formulation and functions by inserting crosslinks between adjacent polymer chains in the compound. A typical vulcanization system in a compound consists of three components: (1) activators; (2) vulcanizing agents, typically sulfur; and (3) accelerators.

vulcanization

Vulcanization

Vulcanization (British: vulcanisation) is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other (synthetic) rubbers via various means.

Vulcanization of EPDM rubber compounds with and without

Vulcanization of industrial-like ethylene propylene diene termonomer rubber compound is studied using a differential scanning calorimetry (DSC). The analysis starts with DSC information to obtain the total transformation heat, followed by an isothermal-dynamic temperature ramp that captures diffusion-controlled reaction kinetics.

Diene rubbers such as natural rubber, SBR, and BR can be vulcanized by the action of phenolic compounds (van der Meer, 1943; Thelamon, 1963; Giller, 1966; Van Duin and Souphanthong, 1995), which are (usually di-)substituted by –CH 2-X groups where X is an –OH group or a halogen atom substituent.
