Bitumen Backing Carpet Tile – Durable Flooring Solution
Bitumen backing carpet tile is one of the most effective flooring solutions for environments that demand both durability and moisture resistance. Therefore, many manufacturers use rubber-modified bitumen as a reliable backing layer to enhance product performance in commercial and residential areas.
Advantages of Using Bitumen as Carpet Tile Backing
- Improves acoustics and indoor air quality
- Provides comfort and thermal insulation
- Offers excellent resistance to moisture and mold
- Allows for quick installation and easy maintenance
How Manufacturers Produce Bitumen Backing Carpet Tiles
First, manufacturers apply a hot-melt bitumen or a bitumen-modified composition to a secondary backing sheet. This layer includes flexible adhesives such as ethylene vinyl acetate to improve bonding. After that, they allow the coated sheet to cool naturally.
Next, workers laminate the cooled backing sheet to the fibrous surface of the carpet base. As a result, the final product demonstrates excellent lay-flat behavior and dimensional stability. In conclusion, this method ensures each bitumen backing carpet tile can withstand heavy use while maintaining quality.
Recommended Bitumen Grade for Carpet Tiles
The most suitable material for the backing layer is oxidized bitumen 105/15. This grade is widely used due to its balance of flexibility and strength under thermal pressure. Below is the detailed specification of this grade:
| Property | Value | Test Method |
|---|---|---|
| Specific gravity @ 25°C | 1.01 – 1.06 | ASTM D-70 |
| Penetration @ 25°C | 10 – 20 dmm | ASTM D-5 |
| Softening point | 100 – 110°C | ASTM D-36 |
| Loss on heating | Max 0.2% | ASTM D-6 |
| Flash point | Min 250°C | ASTM D-92 |
| Solubility in CS₂ | Min 99.5% | ASTM D-4 |
| Spot test | Negative | A.A.S.H. |
Because of its reliability and strength, oxidized bitumen 105/15 is the go-to choice for carpet tile manufacturers worldwide.
