What types of rubber materials are available for the coating?
Exposing an incorrect rubber coating compound to surface oils, cleaning chemicals, or abrasive stone triggers chemical breakdown, causing the coating to swell, peel, or delaminate from the fabric carcass. Sables provides targeted polymer formulations to ensure long-term compound stability:
| Coating Polymer Type | Technical Polymer Characteristics | Target Industrial Environment |
|---|---|---|
| Natural Rubber / SBR (N) | Provides premium high elasticity, unmatched friction coefficient values, and superior tear and abrasion resistance. | General material handling, paper box packaging lines, manufacturing friction feeders, and non-corrosive environments. |
| Nitrile Rubber (NBR) | Highly resistant to mineral oils, hydraulic fluids, hydrocarbons, and vegetable greases. Prevents swelling and softening. | Metal parts stamping lines, oiled automotive component transport, chemical processing plants, and oily recycling sorting. |
| Food-Grade EPDM | Certified non-toxic, odorless polymer formula with high thermal aging resistance and ozone cracking stability. | Direct food contact conveying, agricultural processing, pharmaceutical sorting, and medical component handling. |
Sables application technicians cross-verify your temperature profiles and chemical exposure matrix prior to manufacturing to guarantee the correct chemical bond between the chosen rubber profile and the core backing belt fabric.
