Engineering Guide: Stall Pads

Engineering Insight: The Critical Role of Material Selection in Stall Pad Performance

In industrial applications, stall pads serve as essential components for load stabilization, vibration damping, and structural isolation. Despite their seemingly simple function, the performance and longevity of these components are heavily dependent on precise material selection. Off-the-shelf stall pads often fail to meet operational demands due to a one-size-fits-all approach that neglects application-specific variables such as dynamic loading, environmental exposure, and chemical compatibility.

Standard rubber compounds used in generic stall pads—typically based on natural rubber (NR) or low-grade styrene-butadiene rubber (SBR)—exhibit limited resistance to ozone, UV radiation, and temperature extremes. When deployed in harsh industrial environments, these materials degrade rapidly, leading to cracking, hardening, or loss of elasticity. Such degradation compromises load-bearing integrity and increases maintenance frequency and downtime. Additionally, many commercial-grade pads lack the reinforcement necessary to resist compression set under sustained loads, resulting in permanent deformation and reduced service life.

At Suzhou Baoshida Trading Co., Ltd., we emphasize engineered material solutions tailored to the operational profile of the application. Our approach begins with a thorough assessment of mechanical stress factors, including static and dynamic load ranges, shear forces, and deflection requirements. Equally critical is the evaluation of environmental conditions—such as exposure to oils, solvents, moisture, or extreme temperatures—each of which dictates the optimal elastomer formulation.

For instance, in high-temperature environments exceeding 100°C, ethylene propylene diene monomer (EPDM) or silicone rubber (VMQ) provide superior thermal stability compared to conventional SBR. In oil-rich settings, nitrile rubber (NBR) or hydrogenated nitrile (HNBR) offer enhanced resistance to swelling and chemical breakdown. Furthermore, incorporating fabric or steel reinforcement layers within the rubber matrix significantly improves tensile strength and dimensional stability under prolonged compression.

The following table outlines key material properties and their suitability across common industrial conditions:

Material	Hardness (Shore A)	Temp Range (°C)	Oil Resistance	Compression Set	Typical Use Case
Natural Rubber (NR)	40–70	-20 to +70	Low	Moderate	Light-duty indoor applications
SBR	50–80	-30 to +90	Low	Moderate	General industrial use
NBR	50–90	-30 to +100	High	Good	Oil-exposed machinery mounts
EPDM	50–85	-50 to +150	Moderate	Excellent	Outdoor, high-temp environments
HNBR	60–90	-40 to +170	Very High	Excellent	High-performance industrial systems

Selecting the correct material is not merely a matter of durability—it directly impacts system safety, efficiency, and total cost of ownership. Generic stall pads may offer short-term cost savings, but their premature failure often leads to unplanned maintenance, equipment damage, and production losses. By contrast, engineered rubber solutions from Baoshida ensure reliable performance under real-world conditions, delivering long-term value through precision formulation and rigorous quality control.

Material Specifications

Material Specifications for Industrial Stall Pads

Selecting the optimal elastomer compound is critical for stall pad performance in demanding industrial environments. Stall pads absorb mechanical shock, dampen vibration, and maintain structural integrity under continuous load and exposure to harsh media. At Suzhou Baoshida Trading Co., Ltd., our engineered rubber solutions leverage advanced polymer science to ensure longevity and reliability. This section details three primary materials—Viton, Nitrile, and Silicone—formulated to meet stringent OEM requirements for stall pad applications across automotive, aerospace, and heavy machinery sectors. Each compound undergoes rigorous testing per ASTM D2000 and ISO 37 standards to validate mechanical properties and environmental resistance.

Viton (FKM) fluorocarbon rubber excels in extreme conditions, particularly where exposure to aggressive chemicals, fuels, and high temperatures occurs. Our proprietary Viton blends achieve continuous service temperatures up to 230°C and short-term peaks at 300°C. These compounds demonstrate exceptional resistance to oxygenated fuels, hydraulic fluids, and aromatic hydrocarbons, making them ideal for engine compartment stall pads in high-performance vehicles. Standard formulations deliver 15–20 MPa tensile strength, 150–250% elongation, and 60–90 Shore A hardness. Viton’s low compression set (<25% at 200°C) ensures consistent sealing force over extended cycles, though material costs are higher than alternatives.

Nitrile (NBR) butadiene-acrylonitrile rubber remains the industry standard for cost-effective oil and fuel resistance. Baoshida’s high-acrylonitrile NBR compounds (45–50% ACN content) withstand prolonged contact with mineral oils, greases, and aliphatic hydrocarbons while operating reliably from -40°C to 120°C. With tensile strengths of 18–25 MPa and elongation exceeding 300%, these formulations balance flexibility and durability for dynamic stall pad applications. Standard hardness ranges from 50–90 Shore A, with low-temperature variants maintaining flexibility down to -50°C. NBR’s abrasion resistance and moderate compression set (20–35% at 100°C) support long service life in hydraulic systems and industrial machinery.

Silicone (VMQ) rubber provides unmatched thermal stability across extreme ranges (-60°C to 200°C continuous) and superior resistance to ozone and weathering. Our platinum-cured silicone formulations offer excellent electrical insulation and biocompatibility, suiting them for specialized stall pads in medical equipment or outdoor installations. While tensile strength (6–10 MPa) and tear resistance are lower than Viton or NBR, silicone’s consistent performance under thermal cycling and minimal outgassing are critical for precision applications. Hardness options span 30–80 Shore A, with compression set values of 15–25% at 200°C.

The following table summarizes key comparative specifications for Baoshida’s stall pad materials:

Material	Temperature Range (°C)	Key Fluid Resistance	Tensile Strength (MPa)	Elongation (%)	Hardness (Shore A)	Typical Applications
Viton (FKM)	-20 to 230	Fuels, oils, acids, hydraulic fluids	15–20	150–250	60–90	Aerospace actuators, chemical processing equipment
Nitrile (NBR)	-40 to 120	Mineral oils, greases, aliphatic hydrocarbons	18–25	300–450	50–90	Automotive transmissions, hydraulic machinery
Silicone (VMQ)	-60 to 200	Water, ozone, weathering, some acids	6–10	300–600	30–80	Medical devices, outdoor electrical enclosures

Material selection must align with operational stressors, including fluid exposure, temperature extremes, and mechanical load profiles.

Customization Process

Customization Process for Industrial Stall Pad Manufacturing

At Suzhou Baoshida Trading Co., Ltd., our stall pad customization workflow integrates precision engineering with rubber science to deliver livestock flooring solutions meeting exact operational demands. This four-phase process ensures optimal performance in high-moisture, high-impact agricultural environments while adhering to OEM quality standards.

Drawing Analysis initiates the workflow. Our engineering team rigorously evaluates client-provided CAD files or sketches against ISO 2768-mK geometric tolerancing standards. Critical parameters assessed include dimensional stability under load (±0.5 mm tolerance), drainage channel geometry, and edge contour specifications. We verify compatibility with concrete substrates and identify potential stress concentration zones requiring reinforcement. Material compatibility with common farm disinfectants (e.g., 5% sodium hypochlorite solutions) is cross-referenced against our chemical resistance database. Any deviations from manufacturable design principles trigger collaborative redesign sessions with the client.

Formulation Development follows, where our rubber chemists translate mechanical requirements into compound architecture. Base polymers are selected from SBR, BR, or EPDM families based on required Shore A hardness (60–85 range), with reinforcing fillers like N330 carbon black adjusted for abrasion resistance. Critical additives include zinc oxide for vulcanization control and proprietary anti-aging packages to withstand UV exposure and ammonia degradation. Each formulation undergoes virtual simulation via Moldex3D to predict flow behavior and cure kinetics before physical batching.

Prototyping employs client-approved molds for 3–5 sample units. These undergo accelerated aging tests per ASTM D573 (70°C for 72 hours) and compression set analysis per ASTM D395 (25% deflection, 22 hrs at 70°C). Traction coefficients are measured on wet steel surfaces using a pendulum tester (minimum 0.45 required). Client validation includes on-farm trials under actual livestock loading, with feedback loops for iterative adjustments to durometer or surface texture.

Mass Production commences only after prototype sign-off. We implement statistical process control with real-time monitoring of cure temperature (±2°C tolerance) and press cycle times. Every 500th unit undergoes destructive testing for tensile strength and elongation consistency. Final inspection includes visual checks for porosity (zero tolerance per ISO 4661-3) and dimensional verification via CMM. All batches ship with full traceability documentation including raw material certificates and test reports.

The table below summarizes critical specification parameters for standard versus custom stall pads:

Parameter	Standard Specification	Customizable Range	Test Standard
Shore A Hardness	70 ± 5	60–85	ASTM D2240
Tensile Strength	≥12 MPa	10–18 MPa	ASTM D412
Elongation at Break	≥300%	250–450%	ASTM D412
Compression Set (22h)	≤25%	≤20% (premium grade)	ASTM D395
Abrasion Loss	≤120 mm³	≤90 mm³	ASTM D5963
Ammonia Resistance	10% weight gain max	5% weight gain max	ISO 1817

This systematic approach ensures stall pads deliver 8+ years of service life under 1,000+ daily hoof impacts while maintaining slip resistance on wet surfaces. Our OEM partnership model guarantees seamless scalability from prototype to 50,000-unit production runs with zero quality deviations.
