Multi-Ply Rubber/Fabric Conveyor Belting

Conveyor Belt

Multi-ply conveyor belting consists of polyester/nylon (EP) fabric plies bonded with rubber, topped with a wear-resistant rubber cover on the carrying side and a friction cover on the pulley side. The number of plies and the cover grade determine the belt's tensile strength, abrasion resistance, and suitability for different bulk materials and environments. We supply cut-length belting, endless spliced belts, and chevron/cleated profiles for incline conveying.

Technical Properties

Typical values across stocked grades. Specific grade data sheets available on request.

Number of Plies2–6 ply (EP fabric)
Cover Grade (Carrying Side)3–12 mm (abrasion, oil, heat, or fire-resistant grades)
Cover Grade (Pulley Side)1.5–3 mm
Belt Width300 mm to 2000 mm stocked
Tensile Strength (Belt Designation)EP designation: total belt tensile divided across plies. e.g. EP500/4 = 500 N/mm total belt with 4 plies = 125 N/mm per ply. Per-ply 100–250 N/mm typical; total belt tensile 250–2500 N/mm for fabric carcass
Temperature Range-25 °C to +80 °C (standard); T2 to +125 °C, T3 to +150 °C continuous (170 °C peak), T4 to +200 °C — ratings refer to material temperature, not cover surface
Abrasion Resistance (DIN ISO 4649)Grade M (premium, DIN W/X, ISO H/D) ≤120 mm³; Grade N (general, DIN Y, ISO L) ≤150 mm³
Elongation at Break300–450%

Chemical Resistance

Resistant To

  • Water and mild detergents
  • Mineral ores, aggregates, and dry bulk solids
  • Vegetable oils and animal fats (oil-resistant grade)
  • Mild acids and alkalis at ambient temperature

Limited Resistance

  • Petroleum oils and greases (standard SBR covers swell; use oil-resistant NBR cover grade)
  • Ozone and UV exposure: outdoor installations may require a weather-resistant cover compound

Not Recommended

  • Concentrated solvents (aromatic and chlorinated solvents attack rubber covers)
  • Strong oxidising acids
  • Continuous contact with sharp, hot clinker above 150 °C, which calls for steel cord or ceramic-lined belt

Standards & Certifications

Standards Compliance

AS 1332-2000 (textile-reinforced conveyor belt cover compounds: Grades M, N, X, Y, Z)AS 1333:2024 (conveyor belting of elastomeric and steel cord construction — applies to steel-cord variants)ISO 14890 (textile-carcass conveyor belts — specification)ISO 15236 (steel-cord conveyor belts)DIN 22102 (rubber covers for textile-fabric conveyor belts)DIN 22131 (steel-cord conveyor belts)DIN ISO 4649 (abrasion resistance)AS/NZS 4606:2012 Grade S (FRAS — fire resistant anti-static for underground coal mining; select grades)

Common Applications

  • Mining and quarrying for ore, overburden, and coal transport
  • Aggregate and sand handling
  • Grain and seed handling in agricultural facilities
  • Manufacturing transfer lines
  • Recycling and waste processing plants
  • Ports and bulk terminals (ship loading and unloading)
  • Concrete batching plant feed conveyors

Not Recommended For

  • Standard SBR covers are not oil-resistant. Specify NBR cover for oily or greasy materials
  • Maximum temperature for standard grade is 80 °C; heat-resistant covers required above this
  • Belt tracking and tensioning must be correct to avoid edge wear, mistracking, and premature failure
  • Splicing quality determines belt life: vulcanised splices preferred over mechanical fasteners for high-tension applications
  • Not suited to sharp, heavy lump impact without impact idlers and a thick carrying-side cover

Available Grades

Multi-Ply EP Belt (General Purpose)

SBR rubber covers on EP (polyester/nylon) fabric carcass. The standard workhorse for dry bulk solids — aggregates, sand, grain, and general materials handling. Good abrasion resistance and tensile strength at an economical price point.

Multi-Ply EP Belt (Oil Resistant)

NBR rubber covers providing resistance to vegetable oils, animal fats, and petroleum-based contamination. Required for food processing conveyors, recycling plants handling oily waste, and any application where oil contact would degrade standard SBR covers.

Multi-Ply EP Belt (Heat Resistant — T2/T3/T4 grades)

EPDM or SBR/BR blend covers rated for continuous material temperatures up to 125 °C (T2), 150 °C continuous / 170 °C peak (T3), or 200 °C (T4). Used for transporting hot clinker, dried minerals, foundry sand, and freshly processed materials. Maintains cover integrity and adhesion at elevated temperature.

Multi-Ply EP Belt (FRAS Grade S)

Fire-resistant anti-static belt qualified to AS/NZS 4606:2012 Grade S for use in underground coal mining and other gassy / dust-rated atmospheres. Uses chloroprene (CR) cover compound with anti-static carbon-black loading.

Chevron/Cleated Belt

Multi-ply belt with moulded chevron or cleat profiles on the carrying side, suited to incline conveying up to 35–40°. Prevents material rollback on steep angles. Available in open and closed chevron patterns sized to the bulk material.
