INSERT MADE OF ELASTOMERIC MATERIAL WITH HIGH THERMAL-MECHANICAL PROPERTIES SUITABLE TO FILL THE INNER TUBE OF TYRES FOR BICYCLES, MOTORCYCLES AND LIGHT VEHICLES.

摘要

The present invention refers to an insert made of elastomeric material with high thermal-mechanical properties suitable to fill the inner tube of tyres for bicycles, motorcycles and light vehicles. Wherein the elastomeric phase is composed of thermoplastic polymethane and optionally additional elastomers like SBS, SIS, SEBS, SEPS, from the family of stirenic block copolymers. The expanding agents used are thermoplastic microspheres alone or mixed with chemical foarming agents.
