I,.,...KMi (Ont 7 July 1, 190 hUiPHAHbUM TOi Mr. A. B. Tatistoheff Coebined Raw Materials Board Rooa 4749 SSB FHuU I. T. Iteloy, Director Cork, Asbestos k Fibrous Glass Division CaFUiUKS Root llvj Teepo S oJbJLCTt Substitution of Othsr Rhodesian Chrysotile Asbestos Fibrss and 0 k G Grades In aeeordanos with your request, following is the situation on the previous history of substituting UVL and VRA fibres for C A 0 fibres. In the first place, the C a G/3 and C at 0/4, es we understand, are not critical) and supplies,of these fibres are aaple for the United Kingdoa and the United States. However, last fall we arranged to have 10 tons each of VRA/3 and VRA/4 sent to the United States for experimental purposes. These fibres were evaluated by Johne-Uanville Corporation, which is the chief user of these grades, outside of Keesbey Jettison. They found that the fibres were talcy and not equivalent to the C a G grades and they would not ust then uader any oirouastanoes. Mr. Uuehleck, President of Xeasbey It Mattison, stated that they would nave no use for the VRA/3 and VRA/4 grades. In the oase of HVL/3 and HVI/3XX, Johus-Manville had previous experience with these fibres and found that they are not suitable for tneir use. Mr. Muehleok agreed that he could take 50 percent HVI73 in place of C a G/jt however, he has no use whatsoever for the HVL/3XX. ' In the oase of the VRA/2 and HVL/k, it would be important at this tine to Investigate their suitability for C&O, if it were not already done. Last spring we arranged for a sample of VRA/2. This rlbrc wes very eerefuVly Winlned ly Rsybestoe-Manhattan, Ino., which is the principal user of the C a U/2 grade. They nade very oareful tests of VRA/i against C * G/j, and it was fowd that the shrinkage as received, after crushing and after opening, was considerably in excess of C k g/2. The card shrinkage, as well as the core roving waste, was 4 almost double. The Uneils strength of the yarn mi about 60>peroent lost. This fibro might bo mod 1b od emergency o o substitute for c * but ito value under any tost, whether laboratory or production, in docidodly less. Loot sumesr we had th Rsybeetoe-ttunhettar, Ino., try to got some 1IVL/2 for tsst* To quota fret a latter from Mr. Rohrbaoh, Vioa Prosidont of Raybsetoe-ttanhstten, lae.i "Ae 2 aantionod to you ohon at tho sooting on Friday, Soptoobor 25, Turner A Bewail say. produce some HVV2 froo tho Havelook Mino, whicti say bo uaod in part aa a aubatitute fbr CAU #2. They wore going to experiment with thia fibre and aaaoaa tho value of the grade, and after the production of HVI/2 beooaea standardised, they will, bo doubt, send ua a aaaple so we can try it in our sill. "Tie reeeived this information froo Mr. Shepherd, of Turner A Bewail, during the latter part of August, and on Saptaaber 21, received a letter froa then stating that supplies of HTiy2 are "likely to continue, for soae considerable tine, to suffer froa surface contamination. We feel sure that you will not wish to receive any naturial whiah is not up to proper standard and. representative of.oenpiadous supplies, le therefore propose to leave the order on our books for completion aa soon as the position'mV our Mines sakes this possible. This being so, the oonsignment will be invoiced at the prlca ruling at data of shipment. "Wa shail, no doubt, reeelva additional information froa Turner A Newell aa tha year progresses, and will keep you advised ae soon aa we find out that this is a usable fibre in our production." Until Turner A Newell sees fit to send these saaples, we cannot have a test performed. If saaples of HVL/2 are submitted, we will nake cei lain vhkt they are thoroughly tasted by the users in this country. It saeas to us that the Eriglish would like to force us to use these particular grades, as they era not equivalent in value to tha C&U i'bJb. that# are fully equivalent to C a Uj but if they are, they are certainly vary weioone to keep these other grades and we will be glsd to take the C A G grades.
