Polymer degradation into the bore of the pipe, and fuel leakage and fire may follow. The problem of ozone cracking can be prevented by adding anti-ozonants to the rubber before vulcanization. Ozone cracks were commonly seen in automobile tire sidewalls, but are now seen rarely thanks to these additives. On the other hand, the problem does recur in unprotected products such as rubber tubing and seals. The polymers are susceptible to attack by atmospheric oxygen, especially at elevated temperatures encountered during processing to shape. Many process methods such as extrusion and injection moulding involve pumping molten polymer into tools, and the high
The Sulphur Institute addresses environmental and safety issues surrounding the transportation, production, and storage of sulfur. The Sulphur Institute's program allows regulatory agencies and industry stakeholders to connect, exchange knowledge, and develop practices which improve the safety of the industry. The Sulphur Institute provides members, government and non-government agencies, and industry stakeholders accurate information on sulfur. TSI has served as a source of industry information for many publications including the Wall Street Journal. TSI is often quoted by publications within the industry as well. The information gathered by TSI is made available through a number of publications, webinars, and speaking engagements. The Sulphur
