Heat deflection temperature or long-term use temperature below target requirements
Fenómeno del problema
Heat deflection temperature or long-term use temperature below target requirements
Análisis de la causa
Heat-resistant modifier addition amount insufficient
Poor compatibility between heat-resistant agent and cellulose acetate butyrate, poor dispersion
Improper processing temperature, heat-resistant agent degradation
Other components in the formulation reduce heat resistance
Cellulose acetate butyrate base heat resistance is low, needs significant improvement
Solución
Increase heat-resistant modifier addition amount
Select heat-resistant agents with good compatibility
Control processing temperature to avoid heat-resistant agent degradation
Avoid components in the formulation that reduce heat resistance
Select a high heat-resistant cellulose acetate butyrate grade as the base
Conclusión clave
Heat resistance needs to be addressed from modifiers and formulation
