CEF injection product transparency low
Fenómeno do problema
The haze of the CEF cellulose acetate injection product is >10%, lower than 2%
Análise das causas
The esterification degree of cellulose acetate is low and the crystalline area scatters; the processing temperature is low and the mixing is insufficient
Solução
1) Select cellulose acetate with high esterification degree >55% to reduce crystallinity; 2) Processing temperature 180-220°C; 3) 0.3wt% nucleating agent to control crystallization
Conclusão principal
The transparency of CEF is affected by the esterification degree and crystallization scattering
