[0002]A Thermoplastic material is a plastic material that becomes pliable or moldable above a specific temperature and solidifies upon cooling.When reheated the thermoplastic material can be remoulded into a new shape.In contrast a thermoset material is a plastic that is irreversibly cured from a soft solid or viscous liquid prepolymer or resin and once cured/ hardened a thermoset material cannot be remoulded into a new shape upon reheating. [0003]Thermoplastic elastomers(TPEs)are thermoplastic materials which possess both plastic and rubbery properties.Whilst TPEs have elastomeric mechanical properties,unlike conventional thermoset rubbers,they can be re-processed at elevated temperatures.This re-process ability is a major advantage of TPEs over chemically crosslinked rubbers since it allows recycling of fabricated parts and results in a considerable reduction of scrap. [0004]In general,two main types of thermoplastic elastomers are known,block copolymer TPEs and simple blend TPEs(physical blends).[0005]Block copolymer TPEs contain(i)blocks or segments that are called hard or rigid(i.e.having a thermoplasticbehaviour),typically these have a melting point or glass transition temperatureabove ambient temperature;and(ii)blocks or segments that are called soft which are pliable or flexible(i.e.having an elastomeric behaviour)and typically have a low glass transition temperature(Tg)or a melting point considerably below room temperature.[0006]The expression“low glass transition temperature”is understood to mean a glass transition temperature Tg below15°,preferably below0°,advantageously below-15°C.,more advantageously below-30° C.,possibly below-50° C.[0007]In block copolymer thermoplastic elastomers,the hard segments aggregate to form distinct micro phases and act as physical crosslinks for the soft phase,thereby imparting a rubbery character at room temperature.At elevated temperatures,the hard segments melt or soften and allow the copolymer to flow and to be processed.The hard blocks are generally based on polyamides,polyurethanes,polyesters,polystyrene,polyolefin or a mixture of thereof.The soft blocks are generally based on poly ethers,polyester,polyolefin and copolymers or blends thereof.。
