Corner haze of PCTG products
Fenómeno del problema
Haze increases greatly at corners of transparent products, transparency poor.
Análisis de la causa
Fast cooling at corners causes uneven molecular chain orientation and density, causing light scattering.
Solución
Increase mold temperature at corners; enlarge corner fillet radius; annealing treatment.
Conclusión clave
PCTG corner haze is the optical consequence of uneven cooling.
