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. Examples include silicone rubber via room ...

Investigation on vulcanization degree and residual stress

Based on the vulcanization kinetics equation and the thermo-mechanical constitutive equation, both the vulcanization degree and the residual stress distribution during the vulcanization process of the fabric rubber composites are analyzed by ABAQUS finite model (FM) with user-defined thermal material behavior (UMATHT) and user-defined mechanical material behavior (UMAT) subroutines.

A continuous kinetic model of rubber vulcanization

The kinetics of sulfur vulcanization of rubber presents two specific aspects: The main crosslinking reaction is preceded by an induction period during which the crosslink density increases very slowly (these two steps are generally described separately by existing kinetic models); and can be followed by reversion due to the thermal degradation of unstable polysulfide crosslinks formed during ...

Vulcanizator DTDM

It is especially suitable to butadiene rubber. It is mainly used to manufacture tyres, inner tube, rubber belt, heat-resistance rubber products, etc. Storage: The product should be sealed and stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is one year.

Green Rubber

The process of vulcanization, invented by Charles Goodyear in 1839, made rubber more stable by cross-linking sulfur bonds. Despite extensive research, vulcanization has historically been a non-reversible process with the result that it has not been possible to re-use vulcanized rubber in the production of new rubber products.

Vulcanized Rubber Flooring vs. Non Vulcanized Rubber

Many rubber products you use today are made from vulcanized rubber, including shoe soles, tires, hoses and conveyor belts. The term comes from Vulcan, the Roman god of fire. Vulcanization uses high-pressure and high temperatures after a curative has been added to the raw rubber material.

A Beginner’s Guide to Autoclave | Rubber & Tyre Machinery

Autoclaves are predominantly cylindrical pressure vessels with lids or doors to process your rubber parts that require exposure to elevated pressure and temperature. They are available in a wide range of sizes and design pressures in horizontal (or sometimes vertical) configuration. You use an Autoclave or Vulcanizer (Vulcanizing autoclave) to convert natural rubber into a…

Charles Goodyear and the Vulcanization of Rubber

By Ann Marie Somma. Charles Goodyear’s discovery of the vulcanization of rubber—a process that allows rubber to withstand heat and cold—revolutionized the rubber industry in the mid-1800s.Automotive tires, pencil erasers, life jackets, balls, gloves, and more are all in commercial use because of Goodyear’s relentless experimentation to unlock the molecular structure of rubber—and to ...
