General Introduction:

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

The EP is short for Polyester fabric, which includes polyester toward longitudinal(warp) and polyamide for latitude(weft), EP fabric plies are sandwiched between rubber skim coats for adhesion and load support. Bottom and top cover compounds are added for maximum protection of the belt carcass. The EP conveyor belt consisting of  two to six EP fabric plies, EP rubber conveyor belt has the same merit as Nylon conveyor belt, in addition, EP fabric has the advantages of:

A.Lower longitudinal elongation.

B.Full resistance to mildew, moisture and rotting.

C.Good flexibility and trough ability.

D.Short take-up lengths.

E.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 belt 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.
