While many people experience traumatic events in their lifetime, not all of them will go on to develop post-traumatic stress disorder.
The 3 Main Formulations of ethylene glycol coolant exist are: 1) Silicate based also known as green coolant, 2) Organic Acid Technology based commonly called OAT's, which include extended life or Dex-cool, and 3) Hybrid coolants, which is a combination of organic acid technology mixed with a low dose of silicates.
The solid component can also be a nonionic surfactant, such as a triblock copolymer of ethylene oxide/propylene oxide/ethylene oxide (EO/PO/EO). Said solid nonionic surfactant typically consists of 80% ethylene oxide and has a molecular weight usually greater than about 10,000.. 88-92% of a liquid EO/PO/EO triblock copolymer having the Formula: ##STR14## wherein x+x'=500; y=1,000; molecular weight=1,500; b. 8-12% of a solid EO/PO/EO triblock copolymer having the Formula: ##STR15## wherein x+x'=7,000; y=3,000; molecular weight=10,000.
