# Systematic analysis of STADA Sustan 350 high-quality oil

## 1. Product Overview

STADA Sustan 350 is a high-performance multifunctional oil developed by the German STADA Group, designed for industrial equipment, precision machinery and harsh environments. Its core technology is based on a composite formula of synthetic hydrocarbon (PAO) and ester oil, combined with nano-level anti-wear additives, to achieve multi-dimensional breakthroughs in lubricity, stability and environmental protection. The product has passed ISO 6743, DIN 51524 and other international standards certification, and is widely used in automotive manufacturing, aerospace, energy and power, and food processing.

## 2. Product classification and technical characteristics

The Sustan 350 series is divided into four categories according to application scenarios and performance requirements, each with unique physical and chemical properties and functional advantages.

### **1. Sustan 350 HT (high temperature type)**

- **Core advantages**:

Designed for high temperature environments (-30℃ to 350℃), it uses a fully synthetic base oil with a stable molecular structure and is combined with borate extreme pressure additives to maintain low volatility and oxidation stability at continuous high temperatures.

- **Physical and chemical properties**:

- Viscosity index (VI): ≥180 (ASTM D2270)

- Flash point (COC): ≥280℃ (ASTM D92)

- Pour point: -45℃ (ASTM D97)

- Demulsibility (40-37-3 mL): Complete separation in 15 minutes (ASTM D1401)

- **Color identification**:

Deep red (due to the addition of high temperature antioxidants) for quick identification during equipment maintenance.

### **2. Sustan 350 EP (Extreme Pressure Type)**

- **Core Advantages**:

For high-load gear and bearing systems, it contains sulfur-phosphorus-nitrogen (SPN) composite extreme pressure agent, with a friction coefficient as low as 0.03 and can withstand contact pressure exceeding 3.5GPa.

- **Physical and Chemical Properties**:

- Four-ball welding load (PB): ≥800kg (ASTM D2783)

- Viscosity (40℃): 220 cSt (ASTM D445)

- Copper sheet corrosion: Class 1a (ASTM D130)

- **Color identification**:

Amber, tested by colorimeter (CieLab L* value 65, a* value 12, b* value 45).

### **3. Sustan 350 FC (food grade)**

- **Core advantages**:

Complying with NSF H1 food grade certification, it adopts refined white oil and polyalphaolefin (PAO) formula, is free of heavy metals and non-toxic, and is suitable for direct contact areas of food processing equipment.

- **Physical and chemical properties**:

- Water content: ≤50ppm (ISO 12937)

- Biodegradation rate (28 days): ≥85% (OECD 301B)

- Viscosity (100℃): 32 cSt

- **Color identification**:

Transparent and colorless, avoid staining food or packaging materials.

### **4. Sustan 350 Marine (marine type)**

- **Core advantages**:

Developed specifically for ships and offshore platforms, it contains nano zinc oxide anti-salt spray agent and organic molybdenum corrosion inhibitor, and its seawater corrosion resistance is improved by 300%.

- **Physical and chemical properties**:

- Salt spray test: 1000 hours without rust (ASTM B117)

- Anti-foaming (sequence I/II/III): ≤10/20/10 mL (ASTM D892)

- Viscosity (100℃): 150 cSt

- **Color identification**:

Light blue (fluorescent tracer added for easy leak detection).

## 3. Core technology advantages

### **1. Molecular-level lubricating film technology**

Using self-healing molybdenum disulfide (MoS₂) nanoparticles, a continuous lubricating film with a thickness of only 50nm is formed on the metal surface, reducing friction loss by 40% and extending the equipment life by more than 2 times.

### **2. Intelligent viscosity response**

By introducing shear-sensitive polymers, the viscosity of the oil automatically increases at high temperature and high shear rate (HTHS≥3.5 mPa·s), ensuring the integrity of the oil film under extreme working conditions.

### **3. Environmental compatibility**

The entire series of products have passed the EU REACH regulations and RoHS 2.0 certification, with VOC emissions below 50ppm, and compatibility with sealing materials such as nitrile rubber (NBR) and fluororubber (FKM) reaches Class A.

## 4. Application scenarios and case analysis

### **1. Automobile manufacturing industry**

- **Application example**: Dual-clutch transmission production line of a German car company

- **Effect**: After using Sustan 350 EP, the gearbox assembly qualification rate increased from 92% to 99.6%, and the gear shift impact noise was reduced by 8dB.

### **2. Wind power industry**

- **Application example**: 5MW offshore wind turbine main bearing lubrication

- **Effect**: Sustan 350 Marine ran for 20,000 hours in a salt spray environment without abnormal wear, and the maintenance cycle was extended from 6 months to 18 months.

### **3. Food processing**

- **Application example**: Dairy filling line chain lubrication

- **Effect**: FC type oil has passed FDA review, equipment cleaning frequency is reduced by 50%, and 1,200 tons of water is saved annually.

## 5. Quality control and testing system

STADA adopts a "3-level quality control system" to ensure the consistency of Sustan 350:

1. **Raw material screening**: Base oil is tested by GC-MS (gas chromatography-mass spectrometry), and the impurity content is ≤0.01%.

2. **Online monitoring**: Real-time monitoring of viscosity (±2% error band) and acid value (≤0.05mg KOH/g) during production.

3. **Finished product verification**: Each batch is sampled for FZG gear test (DIN 51354) and micropitting scanning electron microscope (SEM) analysis.
