SG-100 containing stocks are s lig h tly lower than th o se determined f: - e "Carey" 7TS3 counterparts. However, since they contain approxim ate^ j% and 81% of the a sb e sto s formulated in the Carey" counterparts, these small differences again reflect the effective reinforcing value of the SG-100 fiber. * The 3 day w ater expansion data listed in Table II represent average values and ranges determined at two reference points using two specimens of each formulation. Within the precision limits of the test method, all formulations ex cep t p o ssib ly compound f 6_-. show approximately equivalent expansions and are generally within acceptable limits. Although the average e x p an sio n value of compound 7 62A is higher than the other tile formulations tested, its magnitude is considered acceptable and lower than most commer cial tiles tested similarly. Due to its lower delivered cost and reduced required usage level, SG-100 affords a significant raw material savings. For example, compara tive costs provide in Table I result in the following potential savings: Formulation: "Carev" 573 Cost, $/lb. * Savings, $ /lb . v s .

CONCLUSIONS 1. Banbury processing of tile formulations made with SG-100 a s b e s to s has been shown not to degrade this fiber. This is consistent with commercial tile production experience. 2. SG-100 fiber used a t appropriate levels produces tile having hot tensile strengths equivalent to those determined for "Carey" asbestos con taining tile. 3. When properly adjusted for its fiber value, SG-100 formulated tile has binder requirements equivalent to "Carey" 7TS3. -3- . 4 \ he,,uw at! r s e n s itiv ity of tile made with SG-iOO fiber is a -o u t e q u iv alen t to that determined for its "Carey" a s b e s to s co u n tem arr ~Th1c tru. a t the low levels of a s L . o s 'u s TM u 5` Adoption of SG-100 jsb esto s as a replacement for "Carav" f.ber hes been shown to effect subs.an.M l s a v l ^ i ' n L " ua ,ion c o sts $ R.
