EP Conveyor Belt, also known as polyester conveyor belt (NP conveyor belt in the U.S), is short for Polyester fabric. It includes polyester in the longitudinal (warp) direction and polyamide for latitude (weft). EP fabric plies are sandwiched between rubber skim coats for adhesion and load support, and bottom and top cover compounds are added for maximum protection of the belt carcass.

The EP conveyor belt consists of 2 to 6 EP fabric plies. It has the same merits as Nylon (NN) conveyor belt. Its tensile carcass is made of warp polyester and weft nylon knitted fabric, and its performance is characterized by low elongation in the warp direction and excellent troughing formation in the longitudinal direction. The strength of the EP conveyor belt will not decrease in a humid environment, and no mildew occurs. The initial modulus of the polyester is high, and a lower safety factor can be taken. It is suitable for conveying materials under medium and long-distance, high load, and high-speed conditions.

EP rubber conveyor belts are widely used in the mining and processing industries for transporting bulk or lumpy materials such as quarrying, ore, coke, aggregates, crops, sand, clinker, chemicals, construction materials, etc.

EP fabric has the following advantages:

• Lower longitudinal elongation
• Full resistance to mildew, moisture and rotting
• Good flexibility and trough ability
• Short take-up lengths
• Suitable for middle and long-distance transportation of higher load and speed

EP fabric also has excellent compatibility with other rubbers, so it can be combined with any type of cover grade to make it a perfect match for almost any application. This allows EP conveyor belts to convey basically any type of product in any environment — from fine powders to large lumps, from dry to greasy materials, from extremely cold to very hot conditions.

Due to the above excellent performance of EP conveyor belts and their very economical price, they have become the most widely used type of conveyor belt in the world, taking on light and heavy-duty carrying work in the fields of seaport, steel mill, mining, cement plant, metallurgy, agriculture, electric power, chemical industry, etc.

Key Symbols of EP Conveyor Belt

Representation method of EP conveyor belt: EP1000/5 900*5 (6.5+3.0)=200m

The polyester layer is represented by EP. EP1000 means the total tensile strength of the belt is 1000N/mm. The number 5 represents the number of EP layers, so each EP layer will be 200N/mm (each EP layer type is EP200 correspondingly). The number 900 represents the width of the conveyor belt in millimeters. 6.5 represents the thickness of the upper cover rubber, and 3.0 represents the bottom cover rubber thickness. The 200 represents the length of the conveyor belt in meters.
