Performance Change of PBT Products After Chemical Disinfection
Fenómeno del problema
The performance of PBT medical devices declines after chemical disinfection (ethylene oxide, hydrogen peroxide).
Análisis de la causa
The disinfectant erodes PBT or induces stress cracking, and the disinfection temperature accelerates aging.
Solución
Test the influence of the disinfection method on PBT; select a compatible disinfection method; anneal the product.
Conclusión clave
PBT chemical disinfection compatibility needs to be verified.
