Corner haze of PCTG products
Problem Phenomenon
Haze increases greatly at corners of transparent products, transparency poor.
Cause Analysis
Fast cooling at corners causes uneven molecular chain orientation and density, causing light scattering.
Solution
Increase mold temperature at corners; enlarge corner fillet radius; annealing treatment.
Key Takeaway
PCTG corner haze is the optical consequence of uneven cooling.
