Conveyor belts have two basic components: the carcass, or strength member, and the rubber, which protects the carcass.
Most belt carcasses are produced from fabrics that use polyester or nylon fibers, or a combination of the two. These fabrics are completely resistant to the deteriorating effects of moisture, and are resistant to most chemicals. The inherent strength of the fabrics give exceptional resistance to cutting and snagging by abrasive or gritty materials, and retain their strength indefinitely.
The rubber used in conveyor belting, whether natural or synthetic, is compounded to protect the carcass from the material being conveyed, and from any external conditions which could shorten the belt’s useful life. The conveyor belt design seeks to ensure comparable service life for both the cover and the carcass, so that they wear out at the same rate, regardless of conditions.
