PET vs. PC Graphic Overlays
Review material grade, surface, environment, windows, printing, cleaning, forming, and validation when choosing an approach. Record the decision and confirm it against the drawings and samples.
Compare grades, not labels
PET and PC overlay selection depends on forming, flexing, chemicals, surface, optics, and the actual part geometry
Both material families include many grades and finishes. PET is often evaluated for repeated flexing and surface durability, while PC may suit forming or other mechanical needs, but no family-level statement replaces grade data, printing compatibility, sample construction, and exposure tests.
Start with mechanical use
Describe key flexing, emboss depth, forming, bend, thickness, support, cut features, and installation geometry.
Add surface and environment
Identify texture, gloss, scratch risk, cleaners, chemicals, UV, temperature, humidity, and touch frequency.
Compare finished samples
Evaluate printed colors, adhesion, windows, forming, tactile zones, bonding, appearance, and aging using named grades.
Applying the guide
Identify the question, then record the decision
Screen the options against the equipment and operating conditions, then record materials, dimensions, installation, and validation in the project files.
How should PET vs. PC Graphic Overlays be applied to a current project?
Use “Start with mechanical use” to decide whether the guidance fits the equipment, then carry the selected approach for material grade, surface, environment, windows, printing, cleaning, forming, and validation into the drawing, sample checklist, or installation instruction.
When should a decision based on PET vs. PC Graphic Overlays be reviewed again?
Revisit “Add surface and environment” and “Compare finished samples” whenever the material, construction, installation, environment, or acceptance method changes. Material families are not treated as fixed life or chemical-resistance guarantees.
