  • Plastic article having flame retardant properties
    Patent number: 5413828
    Abstract: New plastic articles are disclosed and claimed having flame retardant properties which contain a core of a plastic polymeric material (thermoplastic, thermoset, rigid foam or semi-flexible foam polymeric material) which is coated with a protective, flame retardant layer comprising a mixture of a thermoplastic polymeric material and a flame retardant, char-forming, intumescent system. The new articles are suitable for the manufacture of e.g. rods, beams, pipes, hoses, non-tubular profiles and panels which are useful in various industries such as the building, automotive and mining industries.

  • Rubber compositions with alkoxyalkanoic acid having improved processability vulcanisate properties
    Patent number: 5328953
    Abstract: Alkyloxyalkanoic acids, salts or esters having the formulaR.sup.1 --O--(CR.sup.3 R.sup.4).sub.x CO.sub.2 R.sup.2where R.sup.1 represents an alkyl or alkenyl group, or a hydroxy- or alkoxy- substituted alkyl or alkenyl group, said group containing (apart from the alkoxy carbon atoms in an alkoxy-substituted alkyl or alkenyl group) from 1 to 22 carbon atoms, R.sup.2 represents hydrogen, a metallic or other cationic group, each of R.sup.3 and R.sup.4 represents independently hydrogen or an alkyl group, and x has a value of from 1 to 10, act as agents useful for modifying rubber properties. Compared with conventional processing aids, they improve the processing characteristics of unvulcanised rubber compositions and can have beneficial effect on the physical properties of vulcanisates obtained by the vulcanisation of such compositions.
