Applications of Heavy Components C16 in Industrial Manufacturing

Heavy Components C16 serves a vital role in multiple process-driven sectors due to its distinctive hydrocarbon composition and physical characteristics. As a direct manufacturer, we observe its proven performance, compatibility with diverse formulations, and compliance with advanced industrial standards that support our customers’ production processes globally.

1. Industrial Lubricant Base Stock

We supply Heavy Components C16 primarily to producers of industrial lubricants that operate in metalworking, power generation, and hydraulic systems. Our C16 fraction, processed from straight-run distillation, delivers high viscosity and oxidation stability required for modern lubricant formulations. Manufacturers blend it directly with additive packages to enhance film strength, reduce volatility loss, and deliver consistent lubrication under heavy mechanical load. Optimal results depend on a precise control of hydrocarbon content and the avoidance of excessive light fractions that can compromise finished oil stability.

• API 1509 Base Oil Categories
• DIN 51517-3 (Industrial Gear Oils)
• ISO 6743 (Lubricants, Industrial Oils)
• REACH Regulation (EC) No. 1907/2006 Registration

Typical usage ratio

• 25%–60% of lubricant blend base oil matrix, adjusted based on viscosity index target, with higher shares in heavy-duty and high-temperature formulations

Downstream process integration

• Added after initial solvent extraction and dewaxing, blended with performance additives in heated mixing tanks, followed by vacuum finishing before bottling

Final product types

• Hydraulic fluids (ISO VG 46–100)
• Industrial gear oils
• Compressor lubricants
• Metalworking lubricants

2. Surfactant Production for Detergents

Downstream surfactant and detergent manufacturers use C16 hydrocarbon fractions as alkyl chain precursors during the synthesis of anionic and non-ionic surfactants. By controlling chain length and purity, they achieve desirable foaming, emulsifying, and cleaning functions while adhering to modern eco-requirements. The material enters into sulfonation or ethoxylation reactions, forming key surfactant intermediates for household, institutional, and industrial cleaning agents. Strict batch control ensures the purity profile supports downstream environmental and toxicological compliance.

Industry compliance standards

• OECD Guidelines on Biodegradability
• US EPA Safer Choice Standard
• ISO 9001:2015 Quality Management for Chemical Manufacturing

Typical usage ratio

• 30%–55% as alkylating agent or starting hydrocarbon by total surfactant synthesis input, adjusted for product-specific chain length distribution

Downstream process integration

• Dosed into alkylation or ethoxylation reactors, then neutralized and purified before final compounding with builders and fragrance in detergent blending lines

Final product types

• Sodium C16 alkylbenzenesulfonates
• C16 ethoxylated alcohols
• Heavy-duty laundering detergents
• Hard surface cleaner concentrates

3. Rubber and Polymer Process Oils

Major tire and technical rubber goods manufacturers incorporate our C16 heavy components as plasticizing and processing oils. These paraffinic and naphthenic-rich fractions increase compound flow, improve filler dispersion, and achieve targeted hardness and elasticity in both natural and synthetic rubber processing. Detailed quality screening ensures low polycyclic aromatic hydrocarbon content to meet strict regulatory limits for rubber in contact with skin or food packaging. The process oil directly impacts the physical and rheological properties of vulcanized goods.

Industry compliance standards

• EU Regulation (EC) No. 1907/2006, Annex XVII (PAH restrictions in extender oils)
• ASTM D445 (Kinematic Viscosity for Rubber Oils)
• ISO 21461 (Rubber, PAH Content by NMR)
• China GB/T 24373-2009 (Process Oils for Rubber)

Typical usage ratio

• 10%–40% by weight of total rubber compound, depending on desired hardness, extrusion speed, and end-use specification

Downstream process integration

• Fed during mastication and mixing of rubber, after polymer and filler charging, before addition of vulcanization chemicals

Final product types

• Passenger and truck tires
• Technical molded rubber goods
• Conveyor belts
• Hose and gasket materials

4. Fuel Additives and Blending Components

Refineries and specialty fuel blenders select our C16-range hydrocarbons to modify volatility, lubricity, and combustion profiles of finished fuels for marine, heavy-duty transport, and stationary engines. By introducing precise percentages of this fraction, they optimize point-of-use properties such as ignition quality, lubricating characteristics, and emission control compatibility. Tight control of sulfur, aromatics, and metal trace content ensures that all finished fuels remain compliant with international marine and land-based fuel standards.

Industry compliance standards

• ISO 8217 (Marine Fuels RMG/RME)
• EN 590 (Automotive Diesel Fuel Quality)
• MARPOL Annex VI (IMO Sulfur Cap)

• Injected at fuel blender stage following primary refining and pre-additive dosing, homogenized with finished base fuel, then tested for density and distillation range

Final product types

• Marine bunker fuels (IFO, MDO)
• Low-sulfur diesel blends
• Stationary power generation fuels
• Heating oils

5. Asphalt Modification and Bitumen Additives

Bitumen plants and asphalt product manufacturers utilize C16 hydrocarbons to regulate viscosity, flow temperature, and durability of finished paving and roofing asphalts. By adjusting component ratios, they impart cold flexibility and resist premature hardening under UV exposure. Strict feed quality and real-time monitoring ensure modified asphalt complies with local and international highway and construction standards, while also maintaining workability during transportation and application at job sites.

Industry compliance standards

• ASTM D947 (Residual Asphalt for Roofing)
• EN 12591 (Bitumen and Bituminous Binders)
• AASHTO M320 (PG Binder Specifications)
