Rubber runway granulator
Thermoplastic elastomer Thermoplastic elastomer, also known as thermoplastic rubber, is a polymer material that has the properties of rubber and thermoplastics. It exhibits high rubber elasticity at room temperature and can be plasticized and molded at high temperatures. . It is also the so-called third generation rubber abbreviation or R after natural rubber and synthetic rubber. The structural characteristics of the thermoplastic elastomer polymer chain are composed of resin segments (hard segments) and rubber segments (soft segments) with different chemical compositions. The inter-segment force of the hard segment is sufficient to form physical cross-linking. The soft segment is a highly elastic segment with greater free rotation ability, and the soft and hard segments are arranged in an appropriate order and connected in an appropriate manner. This physical cross-linking of the hard segments is reversible, that is, it loses its ability to constrain the composition of macromolecules at high temperatures and becomes plastic. When the temperature drops to normal temperature, these cross-links recover and act like vulcanized rubber cross-link points. It is precisely because of the structural characteristics of this polymer chain and the reversibility of the cross-linked state that thermoplastic elastomers, on the one hand, display the elastic strength and deformation characteristics of vulcanized rubber at room temperature and other physical and mechanical properties, and can replace general vulcanized rubber in the manufacture of certain rubber products< br/>
