Very high heat stability
PC processes at high temperatures, so only the most heat-stable high-performance pigments survive without shade shift or degradation.
Applications
Pigments for Polycarbonate
Pigment recommendations for polycarbonate with technical checks and export enquiry support.
Polycarbonate is a high-performance engineering plastic processed at high temperatures for optical, glazing, electrical and automotive parts, frequently required to be transparent. This combination demands the most heat-stable, high-performance organic pigments that tint without hazing and without attacking the polymer, since some additives can hydrolyse or degrade PC. Buyers should confirm very high heat stability matched to PC processing, transparency for tinted glazing and lenses, chemical neutrality so the pigment does not degrade the polymer, and, for exterior glazing, weather fastness to preserve tint under sunlight.

What Pigments for Polycarbonate covers
Transparent tint clarity
Glazing and lenses need transparent pigments that tint without hazing, preserving the optical clarity central to polycarbonate applications.
Polymer-safe chemistry
Confirm pigments and carriers do not hydrolyse or degrade PC, since some additives can attack the polymer and reduce strength.
Weatherfast glazing
Exterior polycarbonate glazing faces UV, so specify weatherfast pigments so tinted sheet and panels do not fade outdoors.

Answers
Pigments for Polycarbonate — frequently asked questions
Why does polycarbonate demand the most heat-stable pigments?
PC processes at high temperatures, among the hottest for common thermoplastics, so ordinary pigments would darken or decompose. Only the most heat-stable high-performance organic pigments hold shade and strength through the PC melt. This makes pigment selection for polycarbonate especially restrictive and demanding of validated, high-temperature grades.
Can tinted polycarbonate stay optically clear?
Yes, with transparent high-heat pigments that colour PC without hazing, which is essential for glazing, lenses and light covers. The pigment must survive the high processing temperature and remain transparent. Grades are chosen specifically for clear tinted polycarbonate, where any clouding would undermine the optical purpose of the part.
Do pigments risk degrading polycarbonate?
They can if the pigment or its carrier introduces moisture or reactive species, since PC is susceptible to hydrolytic degradation that lowers molecular weight and strength. Suitable dry, chemically neutral, heat-stable pigment systems avoid this. Always confirm the pigment does not compromise polycarbonate's mechanical or optical properties before scaling up.
What do exterior polycarbonate glazing colours require?
Outdoor PC glazing and roofing face prolonged UV, so tinting pigments must be weatherfast to avoid fading, on top of the high heat stability PC demands. Faded glazing looks poor and signals degradation, so weather-durable high-performance grades are specified and validated under realistic outdoor exposure for exterior polycarbonate.
