Cold Resistant Conveyor Belt

JINFLEX cold resistant conveyor belts are designed for low-temperature environments, widely used in outdoor material transport in cold regions (e.g., Northeast China, Russia, Canada), cold storage warehouses, and frozen food processing plants—suitable for conveying coal, ore, frozen grains, and frozen food at temperatures as low as -45℃.

Our cold resistant conveyor belts comply with China’s industrial standard (HG/T3647) and international standards, including Germany (DIN22131), the United States (RMA), Japan (JIS6369), Australia (AS1333), and South Africa (SABS). The fragility temperature reaches -50℃~-20℃, meeting low-temperature operation requirements.

Product description

Cold Resistant Conveyor Belt

The cold resistant conveyor belt adopts a "low-temperature flexible cover rubber + anti-freezing carcass + cold-stable core rubber" structure, avoiding low-temperature brittleness:

Cold Resistant Cover Rubber: 

Blend of natural rubber and butadiene rubber (NR/BR), with fragility temperature ≤-45℃—maintaining flexibility (Shore A hardness 55-65) without cracking at low temperatures.


Carcass: 

Multi-ply fabric (cotton canvas, nylon canvas, EP canvas) with anti-freezing treatment, no fiber hardening or tensile strength loss at -45℃.


Core Rubber: 

Cold-resistant core rubber with low glass transition temperature (Tg ≤-50℃), ensuring layer adhesion strength ≥6.0N/mm at -45℃.


Edge Protection: 

Flexible edge rubber resists low-temperature cracking, adapting to outdoor wind and snow environments.


Features and Benefits
■ Excellent Low-Temperature Flexibility

Works normally at -45℃, no brittleness or cracking even after 72h cold storage at -50℃; bending test (180° at -45℃) shows no layer separation.


■ High Tensile & Impact Resistance

EP/NN carcass has tensile strength up to 400N/mm, low elongation (≤1.8%) at -45℃; impact resistance ≥40kJ/m², resisting frozen ore impact.


■ Weather Resistance

Cover rubber resists UV radiation and ozone (ozone density 50pphm, 40℃/72h no cracks), suitable for long-term outdoor use in cold regions.


■ Wide Application Adaptability

Suitable for both heavy industrial transport (frozen coal/ore) and light transport (frozen food); food-grade cover rubber option (compliant with FDA) for cold storage.


■ Easy Installation & Maintenance

Flexible belt body is easy to splice (cold vulcanization available); low-temperature wear rate ≤0.15mm/month, reducing maintenance costs.
