Materials
Coreline Rollers manufactures and repairs industrial rubber rollers using materials selected to match real operating conditions. Performance depends on more than the material itself. It’s how that material is built, applied, and maintained in your process.
We work across a full range of rubber compounds to address heat, chemical exposure, load, surface interaction, and environmental demands. Whether you’re troubleshooting performance issues or evaluating a replacement, we help determine the right material and next step for your application.

Material Performance Disclaimer
Important Notice: The chemical, thermal, and environmental resistance data provided in this chart is for general reference purposes only. The listed ratings apply strictly to standard, commercial-grade elastomer formulations under controlled laboratory conditions.
Actual material performance will vary significantly based on compound variables, manufacturing processes, and specific environmental factors.
Custom Formulations: Custom compounding, curing agents, fillers, and polymer blends can significantly alter, enhance, or exceed the baseline limits provided in this chart.
Compounding Variables: Factors such as Acrylonitrile (ACN) content in Nitrile, plasticizer variations, or the use of premium grades (e.g., HNBR vs. NBR) can drastically shift temperature thresholds and chemical compatibility.
Environmental Synergy: Simultaneous exposure to multiple stressors—such as combined high heat, dynamic mechanical friction, UV exposure, and aggressive chemical fluids—accelerates degradation beyond individual test benchmarks.
