Which risk increases when injection-molded polymer films experience thermal gradients?

💡 Explanation

Thermal gradients during cooling exacerbate thickness variations, driving increased thin-film interference because optical path differences change with temperature; therefore fringes appear, rather than uniform optical properties, because thicknesses are uneven.
