FIELD: chemistry.
SUBSTANCE: invention relates to the technology of making cold shrink articles which are used in splicing and protecting sections of wires or cables, different seals and/or insulation of substrates from adverse effects of the external medium in automobile, aerospace, power generation, telecommunication, chemical and defense industry. The cold shrink composition for moulding a tubular elastomeric article having residual deformation less than approximately 35% contains a fluoroelastomer; a homopolymer of epichlorohydrin or polymers obtained from epichlorohydrin; and a peroxide cross linking agent. A cold shrink article is made from the said composition, having an elastomeric element in stretched state and a core which holds the elastomeric element in stretched state and made with possibility of removal. The method of making the cold shrink article involves mixing said components; moulding the obtained composition into an elastomeric article; stretching at least part of the elastomeric article; and inserting the core which is made with possibility of subsequent removal into the stretched part of the elastomeric article.
EFFECT: obtaining articles which are resistant to tearing at high temperatures.
