It is precisely in this second section, where the dangers due to the leakage of sulphuric acid and associated oxides require a special mitigation system, which is intended to avoid toxic cloud formation and its consequent effect on the surrounding civilian population. For example, in October 2008, a leak of concentrated sulphuric acid, at the Indspec Chemical Corporation, caused the evacuation of more than 2 500 people in Pennsylvania, United States (Associated Press, 2008).

HER materials used as chain extenders in this work were prepared based on INDSPEC Chemical Corporation s patented technology and the product details are given in Table 8.1. 

In order to demonstrate that HER compared to butanediol-based elastomer has better physical and mechanical properties at elevated temperatures, cast elastomers with 95% stoichiometry have been made from an MDI terminated polyester prepolymer (Baytec MS-242) extended with butanediol and HER-HP (from INDSPEC Chemical Corporation). Test specimens were cut from a sheet post cured at 110 °C for 16 hours, for the tensile, tear, DSC and DMA determinations. In the preparation of material for the dry heat aging evaluation, tensile, DSC and DMA samples were placed in an air oven with the temperature controlled within 2 °C of the set point and aged for 28 days at 100 °C, 21 days at 120 °C and 14 days at 135 °C. Then, all the samples were stored for at least seven days at room temperature and 50% relative humidity before testing. 

Resorcinol chemistry can aid in developing high barrier polymeric materials, according to Indspec Chemical Corp. Three relevant derivatives are resorcinol dioxyacetic acid (RDOA), bis-(hydroxyethyl)-ether of resorcinol (HER) and resorcinol diglycidyl ether (RDGE). 

Calabrian in Port Neches, XX, is the largest producer of sodium sulfite in the United States. INDSPEC Chemical in Petrolia, PA, and Southern Ionics in Baton Rouge, LA, have about equivalent capacity each. Solvay Chemicals in Green River, WY, and Olympic Chemical in Tacoma, WA, also have some capacity.
