<p>A reinforced elastomer article (see Division B7 comprises linear condensation polyester fibres and an elastomer which has a moisture permeability of at least 20 g./m.2/24 hours and which contains a amine-free accelerator not capable of generating amines under vulcanization conditions. The elastomer is suitably cis-1,4-polybutadiene and may be mixed with natural rubber or SBR. Suitable accelerators are benzthiazyl disulphide, mercaptobenzthiazole, and tetra-alkyl thiuram monosulphides.</p> |
