RITEFLEX LX640 Satin Chrome TPZ Riteflex 640 satin chrome is a thermoplastic elasomer with a Shore D hardness of 40 and a metalic color.

热塑性弹性体分子链是由硬链段和软链段灵活组成的，因此它具有许多热固性弹性体的优点，同时具备热塑性塑料的易加工性。Riteflex弹性体产品在-40℃到121℃（-40° F to +250° F）的温度范围内具有良好的韧性、抗撕裂和抗挠曲疲劳

通过与泰科纳其它聚酯产品的化学结合，Riteflex弹性体不仅具有耐温性能，而且同时也具备了聚酯对通用溶剂、油和油脂及弱酸和弱碱的耐化学性

Thermoplastic elastomers represent an ingenious combination of hard and soft segments so as to provide many of the desirable properties of thermoset elastomers with the processing ease of thermoplastics. Riteflex elastomer products combine toughness, tear and flex fatigue resistance with the ability to perform over a wide temperature range of -40° C to +121° C (-40° F to +250° F).

Their chemical relationship to the other members of Ticona’s polyester family not only gives Riteflex elastomers their temperature capability, but also provides them with the excellent chemical resistance of polyesters to common solvents, oils and greases and dilute acids and bases.
