EP vs NN Conveyor Belt: Construction and Selection

EP uses polyester in the warp and polyamide in the weft; NN uses nylon reinforcement. Choose between them using conveyor tension, elongation requirements and operating conditions.

Understand the reinforcement

The supplied catalogue describes EP as polyester warp with polyamide weft and NN as nylon fabric. Neither designation alone specifies the finished-belt rating, rubber grade or service life.

Review elongation and take-up

Elongation behaviour affects take-up travel and conveyor operation. Compare the actual supplier specification at the required rating and ply construction instead of relying only on the material name.

Keep cover selection separate

Abrasion, heat and oil resistance concern the cover compound and duty. An EP or NN designation does not establish that a belt is heat resistant, food compliant or approved for underground use.

Choose against the actual conveyor

Send tension, length, load, pulley sizes, take-up arrangement and the current belt marking. Request a written comparison for the intended application before substituting constructions.
