Common
Name
ASTM
Designation
General PropertiesBelt Types
ButylIIRExcellent weathering resistance; low permeability to gases; good resistance to ozone and aging; low tensile strength and resilience.White butyl, High-Heat Resistant 2 Ply 220 and 3 Ply 330
EPDMEPDMExcellent weather, ozone and UV resistance; excellent resistance to ketone solvents; superior heat resistance when peroxide cured.High heat resistant 2 Ply 220 and 3 Ply 330
Natural RubberNRExcellent physical properties; good resistance to cutting, gouging and abrasion; low heat, ozone and oil resistance.Pure Gum Roughtop and Steepgrade
NeopreneCRExcellent ozone, heat and weathering resistance; good oil resistance; excellent flame resistance.Compound not currently used in belting industry.
Nitrile/Buna-NNBRExcellent resistance to vegetable, animal and petroleum oils; poor low-temperature resistance.White nitrile food belts; black nitrile light duty; SOR Hot Asphalt
PVC(None)Excellent resistance against acids and chemicals. Weathers well. Limited high and low temperature capability. Obtains other physicals only in combination with polyester carcass.All white and black PVC conveyor and elevator belts; monofilament thermoplastic
SBRSBRGood physical properties; excellent abrasion resistance; not oil, ozone, or weather resistant.Standard RMA-II H.D. conveyor; all transmission; most incline; skirtboard
TeflonAFMVExcellent chemical resistance. Excellent high and low temperature properties.White polyester teflon
UrethanePUExceptional abrasion, cut and tear resistance; high modulus and hardness.Urethane #900; 3 Ply 1/8" Urethane x FS; Urethane Roughtop, Ure-clad
