PBN surface roughness Problem in Injection Processing

Fenómeno do problema

Polybutylene naphthalate PBN exhibits surface roughness in injection processing at 270-300°C.

Análise das causas

Under high-temperature processing at 270-300°C, oxidation causes the problem.

Solução

Solve by drying to a moisture content of <50ppm.

Conclusão principal

PBN ultra-high-temperature processing requires comprehensive protection.
