Most international RFQs say “send office carpet tiles price” but forget the four variables that decide whether the floor lasts 3 years or 10: yarn, dye method, gauge, backing.
Yarn: Solution Dyed Nylon 6/6.6 vs PP BCF
Solution dyed nylon
- Color locked into polymer before extrusion → no bleach fade
- Recovers from compression (chair legs, heel marks)
- Cost ~30–60% above PP
Polypropylene (PP)
- Cheaper, good for low-mid traffic
- Solution dyed PP exists, but abrasion below nylon
- Best for training rooms, back offices, dormitories
For “office carpet tiles wholesale” importers serving corporate clients, lead with SD Nylon 6 + PVC backing as the main line, PP as the value line.
Backing Comparison
| Backing | Pros | Cons | Use case |
|---|---|---|---|
| PVC | Stable, water-resistant, easy glue | Slightly heavier | Offices, humid climates, UAE/Qatar |
| Bitumen | Cheap, rigid, good static load | Softens in >70°C roof-adjacent rooms | Budget EU/UK office refits |
| Cushion PU | Acoustic, soft step | Higher cost | Executive floors, coworking |
| Fiberglass | Dimensional stable | Specialized install | Hospitals, labs |
Dye Method Matters More Than “Color”
“Solution dyed” means UV and chemical fast. “Piece dyed” PP will show bleach spots from office cleaning. Always print Solution Dyed Nylon or Solution Dyed PP on the product title—this is a high-intent filter phrase for European and Australian buyers.

FAQ
Which backing is best for Middle East offices?
PVC. Bitumen can soften near sunny glazed façades; PVC holds shape.
Is polypropylene carpet tile unprofessional?
Not if it’s solution dyed level loop in grey/blue fleck. Used widely in back-office and education.
Can I mix nylon and PP tiles in one project?
Visually risky. Keep nylon in open plan, PP in storage/admin zones if budget-splitting.
