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 temperature vulcanizing and chloroprene rubber (neoprene) using metal oxides.
vulcanization
the various types of rubber used in the various tire compounds all have different vulcanization characteristics, like speed of cure (cure is the crosslinking reaction) and extent of cure (the number of cross-links). a typical passenger car tire is vulcanized for 10 minutes at 170 degrees c. many accelerators and various mixtures thereof are typically used to ensure the vulcanization of all the component compounds have completed during the 10 minute process.
