Lubricating Oil for Paper Machines (ISO VG 150)

1. Product Overview

This premium ISO VG 150 lubricating oil is specifically formulated for the extreme demands of paper machine circulating systems, including felt, press, and dryer roll bearings. It delivers superior oxidative stability and rapid water separation to combat the pervasive steam and water contamination inherent to papermaking. By reducing sludge formation and minimizing wear under high thermal load, this product directly increases mean time between maintenance cycles. Strategically, it offers mill operators a low-risk, high-uptime solution that aligns with total cost of ownership (TCO) reduction targets in competitive pulp and paper markets.

2. Key Specifications & Technical Characteristics

• Chemical composition: Highly refined mineral base oil (Group II) with a zinc-free anti-wear additive package, select demulsifiers, anti-oxidants, and rust/corrosion inhibitors

• Purity / grade: ISO VG 150 compliant; free from chlorine, heavy metals, and solvent-refined aromatics

• Physical characteristics:

  • Form: Homogeneous clear liquid

  • Color: Light amber

  • Viscosity at 40°C: 135–165 cSt (nominal 150)

  • Viscosity index: ≥ 95

  • Density at 15°C: ~0.88 – 0.90 g/cm³

  • Demulsibility (ASTM D1401): ≤ 30 minutes at 54°C

• Packaging options: 208L drums, 1,000L IBC totes, bulk tanker (flexible on-site transfer)

• Shelf life: 36 months in sealed original container, stored between 5°C and 35°C away from moisture

3. Core Industrial Applications

• Primary industry: Pulp and paper manufacturing (tissue, kraft linerboard, corrugated medium, and specialty paper)

• Specific operational use cases: Centralized circulating oil systems for press section roll bearings; dryer section roll bearings; felt roll bearings; and auxiliary gearboxes exposed to wet-end contamination

• Why better than alternatives: Conventional hydraulic-grade oils emulsify rapidly in paper machine condensing environments. This formulation achieves water separation in under 30 minutes, preventing bearing corrosion and lubricant film breakdown. The zinc-free anti-wear chemistry avoids filter plugging and deposit formation on high-speed oscillating rolls.

• Commercial advantage: Extends oil drain intervals by up to 40% compared to standard R&O oils, reducing annual lubricant spend and used oil disposal costs while maintaining ASTM D4310 sludge control below 50 mg/100 mL.

4. Competitive Advantages

• Quality consistency: Produced under ISO 9001:2015 with batch-level spectrometric analysis; each shipment includes a certificate of analysis (CoA) conforming to DIN 51517-3 (CLP) equivalent standards.

• Supply reliability: Dual-sourced base stocks and regional blending facilities ensure 98% on-time-in-full (OTIF) delivery performance to major port hubs (Rotterdam, Houston, Shanghai, Jebel Ali).

• Logistics capability: Dedicated milk-run tanker schedules for recurring bulk orders; drum and IBC shipments via temperature-controlled container options.

• Price competitiveness: Tiered pricing for annual consumption contracts above 100,000 liters; price-protected 12-month corporate agreements.

• Sustainability & compliance: Non-bioaccumulative, no SVHC under REACH, and meets EPA VGP 2013 criteria for environmentally acceptable lubricants where required.

• Technical support: Full Mill Lubrication Survey (MLS) documentation, online condition monitoring guidelines, and 24/5 engineering hotline for troubleshooting.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 4 x 208L drums (832 liters) for first-time trial; 20 MT for recurring bulk contracts.
