Cast vs calendered vinyl: which film for which job

Monomeric, polymeric, cast — three ways to make a PVC film, three different behaviours on a curve. The difference in plain terms, and where each MAXDECAL series sits.

The short answer

Flat and short-term: monomeric. Fleets, box trucks and mild curves for years: polymeric. Deep recesses and compound curves: cast — or ask the desk whether a flexible polymeric will hold.

How the film is made decides how it behaves

All three are PVC. The difference is how the sheet is formed — and that difference follows the film onto every curve for the rest of its life.

Calendered

A hot PVC compound is squeezed between heated rollers into a sheet, then cooled. The sheet keeps a memory of that stretch: pulled over a curve it wants to go back, which shows up as shrink at the edges and lift on recesses over time. Typical thickness 70–100 µm.

Monomeric vs polymeric — both calendered

The plasticiser, the additive that keeps PVC flexible, is the split. Monomeric plasticisers are small molecules that migrate out over time, so the film stiffens and shrinks sooner; economical and fine for flat, short-to-mid-term work. Polymeric plasticisers are larger molecules that stay in the film: more stable, less shrink, longer outdoor life and enough conformability for mild curves.

Cast

Liquid PVC is poured onto a casting sheet and dried into a film with no stretch memory. It sits flat on compound curves and rivets, is usually thinner (around 50–60 µm) and costs more. It is the film for deep recesses and full colour-change on complex body panels.

  • PPFTPU

    Paint Protection Film

    Not PVC at all — TPU with a self-healing top layer, 170–220 µm. A different material for a different job.

    Series page
Honest note. The range on this site is calendered PVC, plus TPU for PPF. If your job needs a cast film — deep recesses, full colour-change on a complex body — tell the desk the panel and the vehicle. You will get a straight answer on whether a flexible polymeric fits, or not.

Six questions that place the job

  1. 01What is the surface?

    Flat, simple curve, compound curve, rivets. This alone rules out most films.

  2. 02How long must it stay on?

    Weeks, a season, years. Match to the published rating, not the brochure headline.

  3. 03Vertical or horizontal?

    Roofs and bonnets take sun and water; horizontal ratings are shorter for every film.

  4. 04Cut or print?

    Cut colour uses the film’s own colour; print needs a printable face plus an overlaminate to protect the ink.

  5. 05Will it come off later?

    Removable adhesives and polymeric films leave the surface cleaner. Plan the removal when you choose the film.

  6. 06What does the job pay?

    Cast on a short-term promo is money wasted; monomeric on a five-year fleet is a callback. Match cost to life.

Two myths worth dropping

“Calendered means cheap”

It means rolled. A polymeric calendered film like 9600 wraps fleets and box trucks with a published multi-year rating. What matters is the plasticiser and the rating, not the word.

“Thicker is better”

Thicker is stiffer. On a curve a thinner, conformable film beats a thick, rigid one. Pick thickness for the job: thick for wear and print stability on flat panels, thin for conformability.

Questions we get asked

Is polymeric good enough for a box truck?
Yes — that is what 9600 is for. Box trucks are large, mostly flat panels with mild curves; a flexible polymeric holds and removes cleanly. Cast is not required there.
Which MAXDECAL film is cast?
The range on this site is calendered PVC plus TPU paint protection film. For cast-class jobs, send the desk the panel and the vehicle and ask — you will get a plain yes or no, not a substitute sold as an equivalent.
What does “3 years vertical / 2 years horizontal” mean?
The published outdoor life when the film faces sideways (vertical) versus up (horizontal — roofs, bonnets). Horizontal always ages faster.

Tell the desk the panel. Get the film that fits.
