| Y6110 By. {R.W. Bailey - Chief Engineer} From Hs {Lord Ernest Hives - Chair} /Wst. c. to Roy. {Mr H. Royce - Buyer} Hs {Lord Ernest Hives - Chair} /Wst.7/MA.15.3.35. FORMAPEX INSULATING MATERIALS. We have now carried out laboratory tests on the samples of the above material submitted for test under cover of By {R.W. Bailey - Chief Engineer} /RD.7/W.5.2.35. Our tests shewed that the Formapex grade CP was inferior to our present standard Bakerlaque material, but the grade CS material compares favourably and is mechanically stronger. We therefore recommend this Formapex CS material as a suitable alternative to Bakerlaque. Hs {Lord Ernest Hives - Chair} /Wst. | ||
