Multi-ply conveyor belts are suitable for medium、short-distance and medium-load transportation of materials,
which are widely used in various fields,for example mine、coal mine、port、metallurgy、chemical engineering、
architecture、electric power station,etc.
Characteristic:
1.Carcass of CC belt is made from cotton and cotton with only average elongation. The most outstanding
characteristic of CC belt is the heat resistant property which comes from natural cotton fabric. CC belt is the
best choice for heat resistant ply belt (under 125° C), but with low strength and shorter life span comparing with
others.
2.EP belt is the most popular and common one for rubber ply belt. The carcass is made from polyester and
polyamide, which generates the advantages of light in weight, impact resistance, sound elasticity, humidity
resistance, low elongation, long life span, and so many more.
3.Carcass of NN belt is made from nylon and nylon. Comparing with CC and EP belt, NN belt is better with higher
elasticity, better troughability, better abrasion resistance, and also higher chemical resistance characteristic.
Application :
----Protection to ply carcass
----Various compounds choices
----Excellent carry side performance
----Anti impact, anti abrasion, and anti tearing
---- Protection to ply carcass

Endless conveyor belt is the belt that has been made into endless without joint during the process of production.
It saves time and labor costs for jointing for customers. Its endless characteristic also generates flat surface and
even tension all around the belt, which provide smoothness of running and low elongation for applications.
The carcass of cold resistant belt is made from polyester, nylon or cotton, and the cover rubber has cold
resistance, impact resistance. According to the cold resistance, this kind of belt has two grades------C1 and
C2. C1: -45 ~ +50℃ ; C2: -60 ~ +50℃ . According to cover rubber, the cold resistant belt can be divided into
three types: general type (L), laceration resistant type(H), and Anti-abrasive type(D).
