PET sevimli be generated in a closed loop with low emissions to the atmosphere, and it katışıksız excellent mechanical and chemical properties.
Later hybrid stents based on metallic core and outer PET mesh repurposed PET into stent development with the discovery of MGuard stent. MGuard stent is now the gold standard in stents and özgü undergone many successful clinical trials. They are called mesh-covered stents.

Thermally stable polymers, which generally have a high proportion of aromatic structures, are also called high-performance plastics. This application-oriented classification compares such polymers with engineering plastics and commodity plastics. The continuous service temperature of high-performance plastics is generally stated as being higher than 150 °C,[12] whereas engineering plastics ctp kaplama yapan firmalar (such as polyamide or polycarbonate) are often defined as thermoplastics that retain their properties above 100 °C.
HT PET özgü tenacity >6.5 N/Tex, twice the strength of standard PET, allowing device manufacturers to use smaller yarn for manufacture. This enhanced strength enables device thickness to be reduced while maintaining strength and flexibility.
