- The long-term (10 years) stress relaxation properties of cellular silicone materials at room temperature are under evaluation. Both equilibrium (random copolymer) and condensation- (block copolymer) type base polymers are included. The equilibrium-type material used urea as the leachable filler, and the condensation-type material used ammonium chloride. Each material was compounded to yield densities of 0.34 and 0.52 g/cm/sup 3/ for thicknesses of 1.17, 1.52, and 2.54 mm. These density-thickness combinations were compressed to nominal compressions of 20 and 40% with nine replicates at each condition. A specially designed fixture was used to maintain a specific compression on the cellular sample, and a universal test machine acquired the load data. Currently, the predicted load retention is between 60 and 68% of the original load.
