Abstract
A NEW synthetic resin known as ‘Leukon’ was exhibited in granular thermo-plastic moulding form at the British Industries Fair by Imperial Chemical Industries, Ltd. The main physical properties of the material are stated to be as follows: density 1-2 at 20° C., impact strength 4 kgm. cm. (Charpy units), tensile strength up to 10,000 Ib. per sq. in., cross breaking strength 80/85 Ib. cantilever, Young's modulus 227 tons per sq. in. The material flows before breakdown under high pressure. As regards the chemical properties of the material, it is said to be insoluble in water, alcohol and aqueous media, to be unaffected by acids or alkalies up to concentrations of 40 per cent in the case of sulphuric acid and caustic soda at atmospheric temperature, and to be unaffected by many high boiling organic esters. It is soluble in certain of its forms in a number of organic solvents, including acetone, chlorinated hydrocarbons and benzene. The material machines easily, can be die-stamped at 120°-140°, has very good insulating properties and low thermal conductivity. A property which is emphasised is the capacity of the material for colour, in transparent, translucent or opaque forms.
