Abstract : Changes in the processing methods and techniques greatly improved the physical properties of uncompounded but cured SiB-2 rubber culminating in 750% elongation. Common silicone fillers proved to be inadequate in enhancing the physical properties of SiB elastomers thus requiring a search for more effective filler materials. SiB-2 type rubber, now being prepared in 600 g. lots by bulk polymerization, must be free of even trace amounts of impurities since these adversely affect thermostability in the 800F and 900F range. SiB rubber films with satisfactory properties down to 11 mil thickness were prepared by several methods. Further progress was made regarding the general SiB elastomer development. (Author)
