materiali_shapeimage_3_med_hrThermoplastic polyester resin is a medium modulus material mainly used in the manufacturing of anti-extrusion rings to support sealing elements.
It provides a winning combination for many parts and components: it gives the flexibility of rubbers, the strength of plastics, and the processibility of thermoplastics.
It provides an extra measure of performance and service life in application where properties such as abrasion resistance and tear strength are critical.
It provides better performance in low temperature environments keeping its good properties (“creep”, impact resistance, fatigue life) at high temperature. Its chemical properties make it highly resistant to hydrocarbons and many other fluids.
