Physical properties of the overlay of the polyester conveyor belt:
| Overlay performance level | Tensile strength Mpa, ≥ | Elongation at break % ≥ | Wear rate mm 3 ≤ | Tensile strength and elongation at break after 70 o C×168h days of aging |
| Strongly split | 24.0 | 450 | 120 | -25~+25 |
| Strong wear type | 18.0 | 400 | 100 | -25~+25 |
| General type | 15.0 | 350 | 200 | -25~+25 |
Layer bond strength: (the highest peak value of all samples must not exceed 20N / mm)
| project | Cloth floor | Between cover layer and cloth layer | |
| Cover thickness 0.8~1.5mm | Cover thickness >1.5 mm | ||
| Average value of all samples N / mm ≥ | 4.5 | 3.2 | 3.5 |
| Minimum peak value of all samples N / mm ≥ | 3.9 | 2.4 | 2.9 |
The general flame retardant type meets the requirements of GB10822-89 standard covering physical properties:
| Cover tensile strength Mpa is not less than | 10 |

Characteristics
1. High strength, thin body and light weight
2. Use EP dipped canvas as the skeleton material
3. The belt body is soft, the groove is good, and the elasticity is good.
4. Impact resistance, wear resistance, corrosion resistance
5. Adapt to larger load, faster and medium and long distance material transportation
6. Smooth operation, no deviation
Joint calculation
Conveyor belt joint cutting length formula calculation:
L=L+(n-1)S+1/2B (single)
L=M[ L +(n-1)S]+1/2B (multiple)
Inner circumference of inner-annular conveyor belt (m)
B — conveyor belt width (m)
n — the number of layers
s — length of each layer of cloth (m)
M — number of conveyor belts
