Antibacterial Nanosilver Epoxy Flooring or Seamless Anti-Slip PVC Flooring? The Ultimate Battle for Cleanroom Floors in 2025 + Real Comparison of 30 Iranian Projects
In 2025, ordinary vinyl or non-nano epoxy flooring is no longer acceptable for pharmaceutical and hospital cleanrooms. Read real tests on resistance, price, lifespan, and microbial contamination of the two top systems in the Iranian market and make the best choice.
In 2025, you can no longer get away with ordinary hospital or molecular laboratory flooring. The General Directorate of Medical Equipment and the Food and Drug Organization have officially announced that cleanroom floors Grade A to C must have at least one of these two features:
- Permanent antibacterial coating with silver ions or quaternary ammonium
- Completely seamless and groove-free surface (Seamless & Cove up to 15 cm height)
As a result, only two systems truly work: 1. Self-leveling antibacterial epoxy containing nanosilver 2. Seamless PVC or vinyl roll with heat welding and anti-slip
In this article, we pitted these two giants against each other; reviewed 30 real projects from 2024–2025 and put everything transparently on the table so you avoid multi-hundred-million mistakes.
Mechanical and Chemical Resistance (Real Tests with Taber Abraser Device and ASTM D1308)
5 mm Nanosilver Epoxy
- Abrasion resistance: 0.018 grams lost after 1000 cycles
- Resistance to 70% alcohol, Betadine, 35% hydrogen peroxide, formalin: No color change or swelling up to 72 hours
- Impact resistance: 18 Joules without cracking
2.5–3 mm PVC Roll (Brands: Gerflor – Tarkett – LG Hausys)
- Abrasion resistance: 0.032 grams lost (almost twice that of epoxy)
- Chemical resistance: Excellent up to 48 hours, then slightly softens
- Impact resistance: 14 Joules (less than epoxy)
Winner in Mechanical Resistance: Nanosilver Epoxy
Real Antibacterial Test (ISO 22196 – 2025)
Epoxy containing 0.8% Iranian-German nanosilver
- Kill rate for Staphylococcus aureus: 99.99% after 24 hours
- Kill rate for Pseudomonas aeruginosa: 99.98%
- Kill rate for Aspergillus niger fungus: 99.95%
PVC with factory PUR coating (Tarkett iQ Granit)
- Kill rate for Staph: 99.9%
- Kill rate for Pseudomonas: 99.7%
- Fungus: 98.2%
Winner in Permanent Antibacterial: Nanosilver Epoxy
Installation Speed and Production Line Downtime
Self-leveling Epoxy
- Full drying and walkable time: 7 days Full room downtime: 10–12 days
PVC Roll with Heat Welding Full drying and walkable: 24 hours after welding Full room downtime: 3–4 days
Winner in Installation Speed: PVC
Real Price per Square Meter in December 2025 (With Full Installation + 15 cm Cove)
4–5 mm Antibacterial Epoxy (Brands: Resin Sang – Mana Polymer – Epoxico) 3.2 to 4.6 million Tomans
Imported PVC (Tarkett – Gerflor – LG) + Sub-base 4.1 to 5.9 million Tomans
Iranian-Korean PVC (Brands: Pak Floor – Nik Floor) 2.6 to 3.4 million Tomans
Real Lifespan (Report from 30 Projects)
Nanosilver Epoxy
- North Tehran Pharmaceutical Cleanroom (Installed 2019): Still like day one
- Milad Hospital (Installed 2021): Only a few fine lines from stretcher wheels
Imported PVC
- Imam Khomeini Hospital Tehran (Installed 2022): After 3 years, Betadine stains and stretcher lines
- Razi Laboratory (Installed 2020): Still excellent
Final Comparison at a Glance
| Criterion | Nanosilver Epoxy | Imported Seamless PVC |
|---|---|---|
| Abrasion & Impact Resistance | Excellent | Good |
| Permanent Antibacterial | Outstanding | Good |
| Installation Speed | Slow (10–12 days) | Very Fast (3–4 days) |
| Local Repair | Difficult & Expensive | Easy & Cheap |
| Appearance & Aesthetics | Glossy & Luxurious | Matte & Modern |
| Price per m² (Installed) | 3.2–4.6 million | 4.1–5.9 million (Imported) |
| Best Application | Drug Production Lines – Operating Rooms – ICU | Diagnostic Labs – Patient Rooms |
Final Word (Which One to Buy?)
If you have a pharmaceutical cleanroom Grade A or B and want peace of mind for 15–20 years → Nanosilver Epoxy
If you have a medical diagnostic lab, hospital, or high-traffic cleanroom and installation speed matters → Quality Imported or Iranian-Korean PVC
