Thermoplastic elastomers(TPE), sometimes referred to as thermoplastic rubbers, are a unique class of engineering materials combining the look, feel and elasticity of conventional themoset rubber with the processing eficiency of plastics.
Due to TPEs are thermoplastics, their melt-processability make them very suitable for high volume injection molding and extrusion. They can also be recyeled. As elastomers, TPEs exhibit true elasticity.
Thermoplastic elastomers (TPE)are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties.
Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The principal difference between thermoset elastomers and thermoplastic elastomers is the type of crosslinking bond in their structures. In fact, crosslinking is a critical structural factor which contributes to impart high elastic properties. The crosslink in thermoset polymers is covalent bond created during the vulcanization process. On the other hand the crosslink in thermoplastic elastomer polymers is a weaker dipole or hydrogen bond or takes place in one of the phases of the material.
