VALUABLE as an insulating lining V for meat and other vehicles, Fomapac is supplied by the London Capsule Co. (1950), Ltd., Empire Works, Mitcham Road, Croydon, Surrey.
It is a foamed and expanded ureaformaldehyde plastic weighing 12-14 oz. per cubic ft. Non-toxic and noninflammable, the slight formaldehyde content makes it impervious to the. growth of bacteria. The thermal conductivity of 0.2 compares favourably with other insulators. For example, that of bitumen-bonded glass fibres is 0.24. of slag wool 0.30, and of cork board 0.27-0.29.
It is non-hygroscopic, but will slowly absorb condensed moisture, unless protected by waterproof skin, such as bitumen or bitumenized paper. It can also be employed as a packing medium for particularly delicate articles embedded in it. The standard-size block measures approximately 3 ft. 10 ins. by 1 ft. 10 ins. by 41. ins.
