Petrochemical ｜ Fundamental Raw Materials for Manufacturing and Maintenance Industries
Key Takeaways
• Petrochemicals are fundamental raw materials for manufacturing, cleaning, and machinery maintenance industries
• Alcohols and paraffins are used as solvents and cleaning agents in industrial and maintenance applications
• Waxes provide coating, surface protection, and modification of material physical properties
• Hydraulic oil is the core of power transmission and operational control in industrial machinery systems
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
Petrochemicals are chemical substances derived from the refining process of crude oil and natural gas. They are used as primary raw materials across various industries, ranging from cleaning and surface treatment to lubrication and hydraulic systems. Selecting the appropriate petrochemical for each application directly impacts performance, safety, and the service life of equipment and machinery.
In industrial plants, problems often arise from selecting unsuitable solvents or lubricants, such as residue formation, premature component wear, or machinery damage. These issues lead to higher costs and production downtime. Understanding the properties and limitations of each petrochemical type is therefore essential for efficient and reliable use.
1. Solvent & Hydrocarbon
• IPA (Isopropyl Alcohol) | CAS No. 67-63-0
A fast-evaporating solvent that leaves no residue. It dissolves water and certain oils effectively. Commonly used for cleaning parts, tools, and electronic equipment.
Suitable for: Cleaning applications requiring quick drying and no residue.
• Ethanol | CAS No. 64-17-5
A versatile solvent with good cleaning performance, mild odor, and wide applicability. Used in chemical industries, food processing, and disinfection applications.
Suitable for: General cleaning and as a solvent in chemical formulations.
• Iso-Paraffin
A branched-structure hydrocarbon with low odor, good stability, and slower evaporation compared to alcohols. Often used as a solvent and carrier.
Suitable for: Industrial cleaning agents and surface coatings.
• Normal-Paraffin
A linear-structure hydrocarbon with consistent boiling points and stable properties. Used as a raw material in various chemical industries.
Suitable for: Industrial applications requiring consistent and controllable physical properties.
2. Wax
• PE Wax (Polyethylene Wax) | CAS No. 9002-88-4
Enhances hardness, surface durability, and reduces material friction.
Suitable for: Plastics, paints, and surface coatings.
• PP Wax (Polypropylene Wax) | CAS No. 9003-07-0
Has a high melting point and improves coating strength and durability.
Suitable for: Printing inks, paints, and specialty coatings.
• Paraffin Wax | CAS No. 8002-74-2
A basic petroleum-derived wax that provides moisture resistance and surface coating properties.
Suitable for: Casting, coating, and packaging applications.
3. Hydraulic Oil
• Hydraulic Oil #32 / #46 / #68
Functions as a power transmission fluid in hydraulic systems, with lubrication, cooling, and protection against wear and corrosion. Grade selection depends on viscosity, environmental conditions, and machinery operating requirements.
Suitable for: Industrial machinery, hydraulic systems, and maintenance work.
Alcohols are suitable for cleaning applications requiring fast drying and no residue.
Paraffins provide stability, low odor, and suitability for industrial applications requiring safety and consistency.
Waxes serve to coat, protect surfaces, and modify material physical properties.
Hydraulic oil is the core of power transmission, lubrication, and operational continuity in machinery systems.
Summary
Petrochemicals are essential components supporting industrial operations in multiple areas, from cleaning and surface coating to hydraulic systems. Selecting products appropriate to the application enhances safety, reduces operational costs, and significantly improves production efficiency.

❓ FAQ
Q: What is the difference between Iso-Paraffin and Normal-Paraffin?
A: Iso-Paraffin has a branched structure, providing low odor and good stability, making it suitable for cleaning and high-performance formulations. Normal-Paraffin has a linear structure with consistent physical properties, suitable for industrial applications and as a chemical feedstock.
Q: Which grade of Hydraulic Oil should be selected?
A: Selection depends on temperature, pressure, and operating conditions. Generally, #32 is suitable for light-duty or low-temperature environments, #46 for general industrial applications, and #68 for high-load or high-temperature operations.
