Memorandum Division Headquarters September 9, 1958 Theraobestos j On Septenber 9, Hassra. Hineon, Jobe, Eaton, Dobson, Qaohas, HcCarty, Blair, and MaoAlpina diaoussad the proa and oons of tha Kaylo and Thamobastos methoda of manufacturing llaa ailioa insulation. Tha following summarises briefly, the advantages and disadvantages of tha two prooeaaea as diseussadt A, Advantages of Kaylo 1. Excellent opportunity for oost redaction 2> Combined autoclaving and drying 3* Wot processing of fiber U. High ohrysotile fiber oontant 5* Quick line 6* Uses sand as a raw material 7* Apparent rapid processing of orders 8. Smaller space requirements 9. Sections nest wall PLAINTIFF'S EXHIBIT K-1520 B* Disadvantages of Kaylo Process 1* Higher "K" faotor 2 Cannot pan cast small sisas 3* Ilepaira to pans lw Uses a parting agent 5* Uses a cardboard liner 6a Can make only a limited xumobar of eaoh siaa 7* Apparently must maintain moisture in product before autoolavlng 8* Large number of Individual mold6 required 9* Blow holes in produot 10. High trim loss in finishing 11, Apparently must maintain a high inventory 12* No hard surface skin on the produot 13* Broken corners Uu High labor oost on bloak 15 Quality below ours in general 16 Poor appearance 17 No large sines 18. Dependant on human element 0 Advantages of Theraobestoa Process 1* Lower conductivity 2* Less dependent on human element 3* Hardness lu Cleanliness 5* General appearance 6* Batter blocks DEFENDANT'S' / ; EXHIBIT. 6z2L 9 - Tbarmoboetoe 2 Saptenbar 9# 1958 0* Advantages of Theraobostoa Frown . 7a Largs pipe sines available 0* Disadvantages of Thernobsatoa Process 1* Cooking of jail 2. frequent prooess aheoka 3* Dal1 nation Ua Process oannot make K-20 (debatable) 5* Pro008a cannot naka formula ohangea (dabatabla) E# It vaa tho oontantion of thooa present that tha following should ba donat Aa Make a dimensional survey on Kaylo (assigned to Don Gaches).
