Riteflex engineering thermoplastic elastomers

Riteflex elastomeric products combine toughness, tear and flexural fatigue resistance with the ability to perform over a wide temperature range of -40 to 121°C. Their chemical relationship to the other members of Ticona s polyester family [8] not only provides Riteflex elastomers with their thermal properties, but also imparts an excellent chemical resistance to common solvents, oils, greases, and dilute acids and bases. Riteflex polyester elastomers are available as unreinforced polymers in a wide range of Shore D hardnesses.

In general, the harder versions have enhanced heat and chemical resistance, while the softer materials possess good low temperature mechanical properties. Table 8 lists some basic properties of these elastomers. 

The range of properties available from Riteflex elastomers is reflected in the diversity of applications, in which these versatile materials have been used, e.g., hoses, tubing, seals, gaskets, belts, pump diaphragms, wire coatings, hooks, fasteners, films, sheets, non-wovens and monofilaments, to name some of the more outstanding.
