Engineering Guide: Rolls Tiles

Engineering Insight: rolls tiles

In industrial rubber manufacturing, the term rolls tiles refers to precision-engineered elastomeric components used in calendering, embossing, and surface finishing applications across sectors such as paper, textiles, plastics, and advanced composites. These components are not merely consumables—they are engineered interfaces where material behavior directly influences process stability, surface quality, and product consistency. A critical yet frequently underestimated aspect of rolls tiles performance is material selection. Off-the-shelf rubber solutions, while cost-attractive in the short term, often fail to meet the demanding operational requirements of high-speed, high-pressure industrial environments.

The failure of generic rolls tiles stems from a mismatch between standardized material formulations and application-specific stress conditions. Common failure modes include premature surface cracking, thermal degradation, loss of durometer under load, and inadequate release properties. These issues arise because standard compounds are typically optimized for broad compatibility rather than targeted performance. For example, a nitrile rubber (NBR) tile designed for oil resistance may exhibit poor resilience at elevated temperatures encountered in continuous calendering lines, leading to permanent set and dimensional instability.

At Suzhou Baoshida Trading Co., Ltd., we approach rolls tiles as system-integrated components. Material selection begins with a comprehensive analysis of operating parameters: temperature range, contact pressure, chemical exposure, surface finish requirements, and dynamic loading frequency. Based on this data, we formulate custom elastomeric blends using synthetic rubbers such as EPDM, silicone (VMQ), hydrogenated nitrile (HNBR), and polyurethane (PU), each offering distinct advantages under specific conditions.

Below is a comparative overview of common elastomers used in rolls tiles applications:

Material	Hardness Range (Shore A)	Temp Range (°C)	Key Properties	Typical Use Case
NBR	60–90	-30 to +100	Oil resistance, abrasion resistance	General-purpose embossing
HNBR	65–95	-40 to +150	High thermal stability, tensile strength	High-speed calendering
EPDM	50–85	-50 to +130	Ozone resistance, flexibility at low T	Moisture-intensive processes
PU	70–98	-20 to +80	Exceptional abrasion resistance, load-bearing	High-wear release rolls
VMQ	40–80	-60 to +230	Extreme temp stability, chemical inertness	High-temp release applications

Custom compounding allows for the integration of functional additives—reinforcing fillers, heat stabilizers, and surface-modifying agents—that enhance performance beyond the baseline properties of the base polymer. Furthermore, precise control over cure kinetics ensures uniform cross-link density, minimizing internal stress and improving dimensional fidelity.

In conclusion, the reliability of rolls tiles is not determined by dimensional conformity alone but by material intelligence. Standardized products lack the tailored response required for mission-critical industrial processes. At Baoshida, we prioritize application-driven formulation to deliver rolls tiles that perform predictably under real-world conditions, reducing downtime and extending service life.

Material Specifications

Material Specifications for Precision Rubber Roll Coverings

Suzhou Baoshida Trading Co., Ltd. delivers engineered rubber roll coverings optimized for industrial manufacturing processes requiring exacting performance under dynamic operational stresses. Our formulations prioritize dimensional stability, abrasion resistance, and chemical compatibility to ensure seamless integration into OEM production lines. Below we detail three core elastomer solutions—Viton, Nitrile, and Silicone—selected for their proven reliability in demanding roll applications such as printing, calendaring, and material handling systems. Each material undergoes rigorous QC validation per ASTM D2000 and ISO 37 standards to guarantee consistency across production batches.

Viton fluoroelastomer excels in extreme environments where exposure to oils, acids, and high temperatures exceeds conventional rubber limits. Its molecular structure provides exceptional resistance to jet fuels, hydraulic fluids, and aromatic hydrocarbons, maintaining integrity from -20°C to +230°C. Viton rolls demonstrate minimal compression set after prolonged thermal cycling, critical for precision coating applications requiring micron-level thickness control. However, its higher cost necessitates strategic deployment in sectors like aerospace or semiconductor manufacturing where failure is untenable.

Nitrile rubber (NBR) remains the industry benchmark for cost-effective oil and fuel resistance in moderate-temperature settings. With acrylonitrile content tailored between 34% and 50%, we achieve hardness ranges of 60–90 Shore A while resisting swelling in aliphatic hydrocarbons, lubricants, and water-based fluids. Nitrile rolls perform reliably from -40°C to +120°C, offering superior abrasion resistance for high-speed conveyor systems. Limitations include vulnerability to ozone degradation and ketone solvents, requiring protective additives in outdoor installations.

Silicone elastomers provide unmatched flexibility across extreme thermal gradients, operating continuously from -60°C to +200°C with transient spikes to +230°C. Its inert composition ensures compliance with FDA 21 CFR 177.2600 for food-grade roll coverings, while excellent electrical insulation properties suit semiconductor wafer handling. Though weaker in tensile strength than Nitrile, silicone’s low compression set and resistance to UV/ozone make it ideal for medical device manufacturing and solar panel lamination processes.

Comparative Material Specifications for Roll Coverings

Material	Temperature Range (°C)	Key Chemical Resistances	Hardness Range (Shore A)	Tensile Strength (MPa)	Primary Industrial Applications
Viton	-20 to +230	Oils, acids, fuels, solvents	65–85	12–18	Chemical processing, aerospace sealing
Nitrile	-40 to +120	Aliphatic hydrocarbons, water	60–90	15–25	Printing presses, automotive conveyors
Silicone	-60 to +200	Ozone, UV, water, steam	40–80	6–12	Food processing, medical device handling

Selection of the optimal elastomer requires analysis of fluid exposure, thermal profiles, and mechanical stress parameters. Suzhou Baoshida’s engineering team collaborates with OEMs to customize durometer, filler systems, and surface textures—such as diamond knurling or micro-patterning—to eliminate slippage and enhance product transfer efficiency. All compounds are formulated without regulated phthalates or heavy metals, adhering to REACH and RoHS directives. For mission-critical roll assemblies, we recommend Viton for chemical-intensive operations, Nitrile for general industrial durability, and Silicone for ultra-broad temperature flexibility.
