Pontos principais
- Expanded PVC sheet, PVC foam sheet and PVC foam board usually refer to the same foamed PVC sheet family.
- For signage, surface flatness, whiteness, ink adhesion and thickness tolerance are more important than the product name.
- Free foam PVC board is common for printing and signs; Celuka PVC board is preferred when a harder skin or screw holding is needed.
- A good RFQ should define application and surface requirement, not only thickness and price.
Checklist RFQ
- Indoor or outdoor signage application
- UV printing, screen printing, mounting or CNC routing
- Required white tone, surface matte/gloss and protective film
- Density and thickness tolerance target
- Packing protection for corners and surface
FAQ
Is expanded PVC sheet the same as PVC foam board?
In many supplier catalogs, yes. Buyers should still confirm density, grade, surface and application fit.
Which PVC board is better for printed signs?
Free foam PVC board is widely used for signage and printing because it balances weight, surface and cost.
