Residual Monomer Test of PBT Injection-Molded Parts Exceeding the Standard
Fenómeno del problema
The content of residual monomers such as 1,4-butanediol in PBT products exceeds the standard.
Análisis de la causa
The raw material polymerization is incomplete and the residual monomer content is high; the processing temperature is too low, and the monomers cannot be effectively removed.
Solución
Select PBT raw material with low residual monomers; appropriately increase the processing temperature to facilitate monomer volatilization; use a vented '2079851475616104452 machine.
Conclusión clave
PBT residual monomer is a test item for food and medical applications.
