YIQI Conveyor has completed a new production batch of 4mm low-temperature PU sidewall conveyor belts, engineered for facilities operating in –25°C to –30°C environments. This upgraded version uses food-grade polyurethane material, delivering the flexibility and crack-resistance required for frozen food processing, cold storage operations, and steep incline conveying.
Why Choose PU for Low-Temperature Environments?
Compared with PVC, PU provides far superior flexibility and durability under sub-zero conditions. The surface remains soft during start-stop cycles, ensuring stable operation even in freezing workshops or refrigerated production lines. These low temperature PU conveyor belts avoid cracking, surface hardening, and stiffness issues common in standard materials.
Key Advantages
- Reliable flexibility at –25°C to –30°C
- Hygienic PU surface suitable for food handling
- High tensile strength for 24/7 operation
- Excellent resistance to cracking in cold rooms
- Lightweight structure reduces power consumption
4mm PU Belt Structure
This model is built with a 4mm single-ply PU construction optimized for small pulley diameters, clean environments, and incline conveying. The smooth PU surface ensures easy daily cleaning while maintaining uniform thickness and strong mechanical properties.
Sidewall Design for Cold-Climate Conveying
Each belt features corrugated PU sidewalls, thermo-bonded with controlled heat parameters to maintain adhesion in freezing temperatures. The strong bonding prevents sidewall detachment and ensures stable conveying on inclines and curves.
Manufacturing & Quality Control
Before packing, each belt undergoes strict inspection, including:
1. Fabric tension calibration
2. PU coating thickness check
3. Sidewall bonding strength test
4. Cooling and shape retention
5. Final dimension verification
Industry Applications
The 4mm PU sidewall conveyor belt is suitable for:
- Frozen food processing lines
- Cold storage facilities
- Seafood and meat packing plants
- Pharmaceutical environments requiring low temperatures
- Refrigerated incline conveying systems
Packaging & Shipment
All belts are rolled neatly, wrapped with moisture-proof kraft paper, and prepared for export. This batch is scheduled for installation in a frozen-goods production facility operating at –30°C.
