    摘要: A volume reducing agent for processing expanded polystyrene (EPS), containing 65-97 wt % of a first plasticizer having a solubility parameter less than the solubility parameter of the polystyrene; and 3-35 wt % of a second plasticizer having a solubility parameter higher than the solubility parameter of the polystyrene. The volume reducing agent is in a liquid state, has a Ferdor solubility parameter close to that of the polystyrene to be processed in the mixed state and transfers the resulting materials having reduced volume into gel-type products to be floated and easily separated to yield a high quality output of recycled expanded polystyrene (FPS).

    摘要: This invention relates to an electrical contact material of silver-indium oxide type, which is produced by the internal oxidation of an alloy consisting of 6-15% by weight indium, at least one of 0.2-8% by weight tin and 0.01-1% by weight magnesium and the balance silver. This alloy may contain further 0.01-1% by weight of nickel.
