GBT 1 is our premium compound designed for improved resistance to cutting, gouging and abrasion.  GBT 1 is the ideal for conveying granite, hard rock ores, quartz,  trap rock and other sharp abrasive materials.  GBT 1 exceeds RMA 1 Specifications DIN Abrasion 90 or less.

HARC is our premium abrasion resistance compound that provides excellent cost savings to most all users.  This compound utilizes rubber characteristics similar to off-road tire tread compound and provides superior wear performance in abrasive applications as well as excellent cut and gouge resistance.  This compound is suited for crushed stone, trap rock, copper ore, taconite, sinter, coke, limestone, cement rock and other abrasive materials.

Oil Resistant Applications

MOR/SC is Medium Oil Resistant and Static Conductive. It is designed to resist the terpenes present in most wood chip applications and the oils present in whole soybeans, whole corn and other moderately oily whole grains where fire resistance is not required.

SOR provides maximum resistance to mineral oils, animal and vegetables fats and oils. This compound provides good abrasion resistance in most applications of oil-treated coal, oily metal and foods containing oil and fats.

OHR provides Oil and Heat Resistance for applications where oil and heat are present.  The primary use is for hot asphalt, oil-coated roofing granules, and hot petroleum coke.  It will withstand temperatures up to 350° (175° C) while retaining moderate abrasion resistance and good flex life.

FR-SBR is designed for use where flame retardance, as well as, good abuse resistance are required.  This compound meets ASTM D-378 and MSHA 2G flame retardance standards.

FR-HA is designed for use where flame-retardance, high abuse and abrasion resistance are required.  This compound meets ASTM D-378 and MSHA 2G flame retardance standards.

FR-OR-SC is designed for use where flame retardance and moderate oil resistance is required.  FR-OR-SC  is recommended for use in grain handling and oil treated coal.  This compound meets ASTM D-378 and MSHA 2G flame retardance standards.

Heat Resistant Applications

HR-250 is a moderately priced compound that offers excellent abrasion resistance and will withstand temperatures up to 300° (150°C) for lumpy materials when maintaining a belt surface temperature no greater than and 250° (95°C).

HR-400 is a premium quality compound that offers excellent abrasion resistance and good heat resistance in conveying lumpy materials up to 400° (205°C) when maintaining a belt surface temperature no greater than 300° (150°C).

HR-750 is a premium EPT compound offering excellent heat resistance and good abrasion resistance in conveying lumpy materials up to 750° (400°C) when maintaining a belt surface temperature no greater than 400° (205°C).
