Metal oxide vulcanization – Rubber Manufacture
Metal oxide vulcanization is of great importance to chloroprene rubber, chlorobutyl rubber, chlorosulfonated polyethylene, chlorohydrin and polysulfide rubber, especially chloroprene rubber, which is commonly vulcanized with metal oxides. When chloroprene rubber is vulcanized, the allyl chloride structure produced by 1,2-polymerization is used ...

Effective vulcanization system – Rubber Manufacture
In the vulcanized rubber network obtained by the above two combinations, the content of single bond and double bond accounts for more than 90%, and the network has little main chain modification. The utilization rate of sulfur in the vulcanization system is high, and it is called effective vulcanization system (EV).

Purpose and process of metal skeleton blasting – Rubber
Rust, oxide and other contaminants make the bond between the rubber grommets and the metal stronger. The purpose of sand blasting is as follows: remove rust spots, welding slag, carbon deposits and other contaminants on the surface of the skeleton; Make the surface of the skeleton rougher and increase the bonding area with the rubber grommets.

More than 70% of the vulcanized rubber network obtained by the ordinary sulfur vulcanization system is a polysulfide cross-linking bond, which has a relatively strong main chain modification. Vulcanized rubber has good initial fatigue properties, and has excellent dynamic and static properties at room temperature.

Y. Ikeda, in Chemistry, Manufacture and Applications of Natural Rubber, 2014. 4.1 Introduction: The importance of sulfur cross-linking of rubber. Vulcanization is a cross-linking reaction by sulfur that generates three-dimensional network structures in rubber and is the best-known process of giving rubber products greater stability. Vulcanization was discovered by Goodyear in 1839 before the ...

What is vulcanised rubber?
Vulcanization or vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials via the addition of sulfur or other equivalent curatives or accelerators. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains.
