Application：
Suitable for middle and long distance conveying of
materials such as coal, ore or other product
under high load, speed, impact and heavy wear.
Characteristics
• Good elasticity, anti-impact;
• High adhesion, good flexing capacity;
• Good troughability;
• Higher strength, smaller thickness and weight compared with CC belts;
• Good resistance to moisture and heat, corrosion resistance
• Good wearability and long service life.
