The molecular chain of TPC-ET thermoplastic polyester elastomer is composed of hard chain segment and soft chain segment flexibly, so it has many advantages of thermosetting elastomer, but also has the machinability of thermoplastic. Riteflex® products have excellent toughness, tear resistance, and flexure fatigue resistance in the temperature range -40° C to 121 ° C (-40° F to +250° F). By chemical combination with other Tycona polyester products,Riteflex® TPC-ET not only provides temperature resistance, but also provides polyester chemical resistance to universal solvents, oils and greases, and weak acids and bases. Riteflex® TPC-ET non-reinforced grades are available in a wide range of Sau D hardness. Generally, the higher the hardness, the better the heat and chemical resistance, whereas the softer the material, the better the low temperature mechanical properties.
