Sulfur vulcanization
Worker placing tire in a mold before vulcanization. Sulfur vulcanization or sulfur vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials by heating them with sulphur, or other equivalent curatives or accelerators. Sulfur forms cross-links (bridges) between polymer chains.

Vulkacit®. Vulcanization is the conversion of a high-molecular material from the plastic to the elastic state. One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the rubber industry, requires the use of vulcanization accelerators such as Vulkacit.

Vulcanization - an overview | ScienceDirect Topics
Vulcanization is the process to chemically convert a polymer compound (rubber) to an elastic and final end-use product (i.e., in its final shape). The process is dependent on time, temperature and the processing method. Typical equipment used include a press, autoclave, oven, fluid beds, microwave, combinations of techniques.

present in the GTR particles and in the rubber compounds. Vulcanization accelerators are applied as reclaiming/ devulcanization agents, as they have effect on the process of breakdown of cross-links and on secondary vulcanization of resulting reclaimed rubber [1617, ]. Widely promoted in the 90s of last century product from STI-K Polymers American
Send InquiryLecture No. (12) Rubber Vulcanization
The vulcanization reaction can be modified in various desirable ways by using accelerators and activators. Because of when sulfur is used in the rubber vulcanization, the cure rate is slow to form polysulfide links and cross-linking with sulfur alone is quite inefficient and requires curing times of about (3 to 5) hours.

Organic accelerators. In the early years of rubber production, high quality natural rubber was obtained from the tree, Hevea braziliensis, found in the regions bordering the Amazon river. The high quality rubber exhibited desired properties, such as a high tensile strength (greater than 2800 psi) and a two-hour vulcanization time. Vulcanization is the process by which natural rubber is ...

Vulcanization
Accelerated vulcanization is carried out using various compounds that modify the kinetics of crosslinking, this mixture is often referred to as a cure package. The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber) and styrene-butadiene rubber (SBR), which are used for most street-vehicle tires. The cure package is adjusted specifically for the substrate and the application.

Sulfur Vulcanization
Sulfur Vulcanization of Rubbers (polydienes) Vulcanization of rubber by sulfur alone is extremely slow and can take several hours at elevated temperatures (140°C or more). This is problematic because long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties.
