RUBBER PRODUCTION

ELASTOMERS

Elastomers are crosslinked (vulcanized) polimerik goods that brittle like glasses at too low temparatures , shows no viscose fluidity even too high temparature , shows good elasticity wide range in between room and breaking down temparature .

TECHNOLOGY OF ELASTOMER

Uses producting of very important and functional parts for human life, eg , fuel and break hoses , wipers , transmition belts , seals , axle bellows , radiator and air hoses ,door and window sealings , shouck absorbers and insulation elements etc.Elastomer supports used at free ways and briges , expanding seals , sealing of dirinking water pipes and producting of conveyor belts.
