Survives reheat for forming
Thermoformed sheet is reheated after extrusion, so pigments must withstand two heat exposures without shade shift or degradation.
Applications
Pigments for Sheet Extrusion
Pigment recommendations for sheet extrusion with technical checks and export enquiry support.
Sheet extrusion produces thicker gauge sheet for thermoforming, signage, panels and packaging from resins like PS, PET, ABS and PP. Because sheet is often subsequently thermoformed and may be viewed in transmission, organic pigments must be heat stable through both extrusion and reheating for forming, disperse without specks visible in the flat sheet, and, for transparent tints, colour without hazing. Buyers should confirm heat stability covering the forming reheat, even dispersion for uniform flat colour, migration control where sheet is thermoformed into packaging, and transparency or opacity matched to the end product.
At a glance
What Pigments for Sheet Extrusion covers
Flat, even colour
Large flat sheet reveals any streak or speck, so pigments must disperse evenly for uniform colour across the width.
Transparent tint clarity
See-through tinted sheet needs pigments that colour without hazing, keeping the transparency required for display and packaging.
Migration for formed packs
Sheet thermoformed into food or goods packaging needs low-migration pigments so colour does not transfer into contents.

Answers
Pigments for Sheet Extrusion — frequently asked questions
Why must sheet-extrusion pigments survive two heat cycles?
Sheet is heat during extrusion, then reheated during thermoforming into the final part. Pigment must tolerate both without shifting shade or degrading. A grade adequate for single-pass extrusion could still fail on forming reheat, so validate heat stability across the full sheet-plus-forming process.
How is even colour achieved across wide sheet?
Large flat sheet shows any unevenness, so pigment must be well dispersed and uniformly metered across the die width. Quality masterbatch and consistent feeding prevent streaks and colour bands. Poor dispersion or uneven let-down produces visible variation that is obvious in flat, often backlit, sheet products.
Can I make transparent tinted sheet with organic pigments?
Yes, using transparent grades that colour the resin without hazing or clouding it. This suits display packaging, signage and light panels where see-through tint is wanted. Opaque grades are chosen instead where the sheet must hide contents. Match transparency or opacity to the intended visual effect.
Does the resin type change sheet pigment selection?
Yes. PS, PET, ABS and PP have different processing temperatures and characteristics, so heat rating and compatibility must match the specific resin. Styrenics limit heat and migration, PET runs hot, and PP adds warpage concerns. Always select the pigment for the actual sheet resin, not sheet extrusion generically.
