Heavy Duty Conveyor Belt (EP)
High and Low Temperature Resistance
Rubber Conveyor Belt Carcass Construction Impacts The Belt Tension Ratings:
The internal reinforcements and fabric plies which provide the mechanical strength to the belt. Made up of fabrics like polyester, nylon, cotton.
Number of Plies
More plies provide higher tensile strength to resist tension forces. Tension rating increases with more plies. 2-ply is around 400 PIW. 6-ply reaches 1200 PIW.
Rubber coating properly bonded to fabric carcass ensures the plies work together. Poor adhesion weakens the belt strength.
Thinner but stronger fabrics allow more plies to be stacked in the same belt thickness. Increases strength without sacrificing flexibility.
Multi-ply belts with cross-oriented 0° and 90° plies provide good lateral and longitudinal stiffness. Helps under load.
Polyester provides the highest tensile rating per ply. Aramid fabrics offer very high strength-to-weight ratio.
Skim rubber coats applied between plies help reduce internal ply friction and shear. Improves belt flexibility.
Rubber coated fabric strips layered between plies to improve impact and flex fatigue resistance in the belt.
Total carcass thickness specified in 1/16 inch increments. More plies increase the gauge and tension rating.
Sewn fabric along belt edges helps reinforce and prevent ply separation and lifting under load.
The carcass construction and design directly influence the belt’s tension strength, capacity, and overall durability in a conveyor system.
Rubber conveyor belt is made of a blend of polyester/nylon fabric consists of polyamide for weft and polyester for warp which makes it strong and flexible. Rubber skim coats ensure adhesion and load support, with top and bottom cover compounds for maximum protection.
Belt conveyors are widely used in material handling systems in manufacturing – cement, aggregate, stone crusher plant, mining, coal and power steel industries for transporting heavy or bulky materials. They are durable, heat-resistant and have excellent tear and abrasion resistance.

Key Ratings And Specifications For Rubber Conveyor Belting Related to Plies:
Number of Plies
Layered fabric reinforcements inside the belt carcass. More plies increase strength and load capacity. Common ply ratings are 2, 3, 4, 5.
Polyester and nylon are common conveyor belt ply fabrics. Polyester provides greater strength while nylon offers flexibility.
Measured in tension strength per ply. Rubber belts typically have 400-500 lbs per ply per inch of belt width.
Overall Belt Strength
Determined by multiplying ply rating by number of plies. A 3-ply belt with 400 lb/ply/in rating has 1,200 lbs per inch belt strength.
Maximum tension force the belting can withstand repeatedly without damage. Depends on number of plies.
More plies spread load stresses over larger area providing better load support and lengthening belt life.
Belts with fewer plies generally trough and flex easier around pulleys. Multi-ply belts tend to be stiffer.
Number of plies impacts splice strength and fastener grip. Thicker belts need heavy duty fasteners.
Ply fabric thickness. Thinner gauge fabrics allow more plies in the same belt thickness.
EP conveyor belt Applications
Features of EP/Nylon Conveyor Belt
High Tensile Strength
The tensile strength of EP conveyor belt is generally between 800-2500 N/mm. The higher the tensile strength, the more resistant the belt is to tearing and
Abrasion & Wear Resistance
They are also resistant to wear, which helps them to last for a long time. EP conveyor belts can handle a wide range of temperatures, from up to 200°C, and can be used in high-temperature environments.
