Thickness first
Two prices mean the same thing only after thickness is written in millimetres or inches on both replies.
expanded pvc foam board
Turn expanded pvc foam board into a request several factories can quote on the same basis. PVC Foam Board Sourcing issues one list: thickness in mm or inches, sheet size, density in g/cc, cell structure, quantity, packing and destination. We do not publish a price list and we do not fill missing axes.
What every expanded pvc foam board quotation must state
Size on the same line
A 4x8 parent is 48 x 96 in. A remnant pack is a different good even when the name matches.
Density as a grade field
Ask density in g/cc or g/cm3 and the method. “Light board” is not a number.
Inside the price
Pallet wrap, corner boards and export marking sit inside the price only when the factory writes them there.
Evidence, not a claim
Each supplier attaches the current document for the quoted item, not a general capability paragraph.
How the same-basis request is issued
1
Capture axes
Thickness, size, density, cell structure, color/finish, quantity and destination.
2
Separate extras
CNC routing, digital print and special crates stay visible as extras unless they sit on the priced line.
3
Evidence asks
Lot files replace a company brochure. A plant ISO file is not a sheet certificate.
4
Compare replies
Two offers that answer the same list can be compared. An offer that answers three items is not yet a competitor.
Send the expanded pvc foam board list
If a factory proposes a different density or a different cell structure, treat that as a new request. Re-issue the line with the changed axes visible.
