Stress-Induced Cracking of Fluorocarbon Rubber MTL-0002 After Exposure to DS-2
Abstract
Fluorocarbon Rubber 0002 (MTL-0002) (1) was found to be susceptible to stress-induced cracking (SIC) when exposed to the standard decontaminant DS-2 (2). In this report, several tensile tests were conducted upon this rubber and related fluorocarbon elastomers after exposure to DS-2 and its components. It was found that diethylenetriamine, a DS-2 component, was responsible for the formation of cracks under tension. Of the vulcanizates tested, MTL-0002 was the most susceptible to SIC after a one-half hour immersion in DS-2, but 1. B. Moore V7D failed at lower stress levels after 24 hours of immersion in DS-2. It is suggested that changing the proportion of magnesium oxide and calcium hydroxide in the recipe and altering the press curing temperature time may enhance the resistance to SIC of MTL-0002.
